Why SMT Line Speed Matching Matters for High-Volume Electronics Manufacturing<\/h2>\n

Picture this. You’ve got a pick-and-place machine running at 80,000 CPH. Your stencil printer is cranking out boards fast. So you bump up the conveyor speed on your reflow oven to keep things moving. Smart move, right?<\/p>\n

Not exactly.<\/p>\n

What often happens is the bottleneck just shifts. Your faster oven now pushes boards into an AOI station that can only handle so many inspections per minute. Or your inspection queue backs up and creates jams that slow down the whole line. You spent money on speed upgrades, but your boards-per-hour number barely budged.<\/p>\n

This is the core challenge in SMT throughput optimization. It’s not about making individual machines faster. It’s about making them work together at the right pace.<\/p>\n

For manufacturers producing smartphones, automotive electronics, semiconductors, or aerospace components, this matters big time. You need higher yield, lower labor cost, and lead-free compliance all at once. Adding speed without balance can create defects, increase rework, and wipe out any productivity gains you thought you were making.<\/p>\n

Good news. There’s a practical framework for SMT line balancing that protects quality while actually improving throughput. That’s exactly what we’re walking through in this article.<\/p>\n

Whether you’re running a mixed-model line or a dedicated high-volume cell, the approach is the same: understand your true constraint, measure what matters, and tune the system, not just the single station.<\/p>\n

Let’s get one thing straight right away. SMT throughput optimization is not about making one machine run faster. It’s about getting more completed, good boards out the door per hour.<\/p>\n

Sounds simple, but here’s where it gets tricky. Your pick-and-place machine might claim 80,000 CPH on the spec sheet. Your reflow oven might say it can handle 500 boards per hour. But what actually matters is how many boards pass inspection and leave the line without needing rework.<\/p>\n

That’s the real number.<\/p>\n

Here’s why you need to watch more than just machine speeds:<\/p>\n

Rated capacity<\/strong> is what the equipment manufacturer promises under perfect conditions. Think of it like a car’s top speed on a test track.<\/p>\n

Takt time<\/strong> is the pace you need to meet customer demand. If a customer wants 1,000 boards per shift and you run one shift, your takt time is one board every 2.9 minutes.<\/p>\n

Cycle time<\/strong> is how long each station takes to process one board. The slowest cycle time sets your maximum line speed.<\/p>\n

First-pass yield<\/strong> tells you what percentage of boards pass inspection without needing any rework. Low yield means your throughput numbers look way better than they actually are.<\/p>\n

WIP<\/strong> (work in progress) builds up when one station runs faster than the next one. Too much WIP means boards sit waiting, and that creates quality problems.<\/p>\n

So when we talk about throughput optimization in 2026, we’re talking about balancing all of these factors together, not just cranking up speeds.<\/p>\n

Key Terms Glossary<\/h3>\n

| Term | What It Means | Why It Matters for Throughput |
\n|——|—————|——————————-|
\n| Rated Speed | Maximum machine speed under ideal conditions | Usually higher than real-world output |
\n| Takt Time | Required production pace based on customer demand | Sets your actual target speed |
\n| Cycle Time | Time for one station to process one board | The slowest station limits line speed |
\n| First-Pass Yield | Boards passing inspection without rework | Low yield kills effective throughput |
\n| WIP | Work in progress sitting between stations | Too much causes delays and defects |
\n| Bottleneck | The station that actually limits your output | Where you focus improvement efforts |
\n| Line Balance Rate | How evenly work is distributed across stations | Poor balance means idle time and slowdowns |<\/p>\n

One thing I see all the time: teams chase rated speed on one machine without checking if that actually helps the final output number. A reflow oven running at full speed means nothing if boards come out with cold solder joints and need rework.<\/p>\n

That’s why the best approach measures the whole system, not just individual pieces. You want to know your true bottleneck, your real yield, and your actual boards-per-hour output. Those numbers tell you where to focus.<\/p>\n

\n

Expert Tip:<\/strong> Before adjusting any machine speed, measure your current first-pass yield and rework rate. A 5% increase in yield often improves effective throughput more than a 10% speed boost on the fastest machine in the line.<\/p>\n<\/blockquote>\n

The goal is straightforward. You want every station working together at a pace that maximizes good output, not just machine utilization. When one station runs flat out while others wait, you’re not optimizing. You’re just creating problems downstream.## Map the True Constraint Before Adjusting Machine Speeds<\/p>\n

Here’s a fact that trips up a lot of teams. The machine with the slowest rated speed is not always your real bottleneck. Changeover time, inspection queues, board transfer delays, and reflow dwell time often control your actual throughput more than any machine’s top speed.<\/p>\n

Let me show you what I mean.<\/p>\n

Break Your Line Into Process Stations<\/h3>\n

Every SMT line has distinct stations. You need to map all of them, not just the obvious ones:<\/p>\n

    \n
  • Loader<\/li>\n
  • Stencil printer<\/li>\n
  • Solder paste inspection (SPI)<\/li>\n
  • Pick-and-place<\/li>\n
  • Reflow oven<\/li>\n
  • AOI or AXI inspection<\/li>\n
  • Conveyor buffers<\/li>\n
  • Unloading<\/li>\n
  • Any manual handling steps<\/li>\n<\/ul>\n

    Most teams only watch the printer, placer, and oven. They miss the time eaten up by SPI review queues, inspection rework, and feeder replenishment between runs.<\/p>\n

    Measure Cycle Time at Each Station<\/h3>\n

    This is where most lines fall short. They use rated speeds from spec sheets instead of actual measured times. Here’s what to do:<\/p>\n

    Time your stencil printer. Then time your pick-and-place. Then your reflow oven. Then your AOI. And yes, time your unloading station too.<\/p>\n

    The slowest measured time is your constraint. Not the spec sheet number.<\/p>\n

    Here’s a quick example from a real line I worked with:<\/p>\n

    | Station | Rated Speed | Measured Cycle Time | Gap |
    \n|———|————-|———————|—–|
    \n| Printer | 60 sec\/cycle | 58 sec | Close |
    \n| Placer | 75,000 CPH | 52 sec | Real speed lower |
    \n| Reflow | 500 boards\/hr | 48 sec | Slower than placer |
    \n| AOI | 15 sec\/board | 68 sec | Hidden bottleneck |<\/p>\n

    That AOI station looked fine on paper. In reality, it was the constraint that held back the whole line.<\/p>\n

    Why Queues and Changeovers Create Hidden Bottlenecks<\/h3>\n

    Boards don’t process instantly between stations. They wait. That waiting time adds up fast.<\/p>\n

    Feeder replenishment on a pick-and-place can eat 3-5 minutes per setup. Changeover time on an SPI program might add another 2 minutes. Manual inspection review for complex boards could take 10 minutes per batch.<\/p>\n

    These delays hide in plain sight because nobody times them separately.<\/p>\n

    \n

    Expert Tip:<\/strong> Before adjusting any machine speed, measure your actual cycle time at every station over a full production shift. The station with the longest real cycle time is your constraint, and that’s where speed improvements actually matter. Everything else is secondary until you solve that bottleneck.<\/p>\n<\/blockquote>\n

    Once you know your true constraint, you can make smart decisions about where to focus improvement effort. And that’s the foundation for everything that follows.## Calculate Line Speed From Board Complexity, Not Machine Nameplate Capacity<\/p>\n

    Here’s something that trips up plenty of purchasing decisions. That 80,000 CPH on your pick-and-place spec sheet? It’s measured under perfect lab conditions, not on your actual production floor.<\/p>\n

    Real SMT throughput depends heavily on what you’re actually building.<\/p>\n

    \"Close<\/figure>\n<\/p>\n

    What Actually Slows Down Placement<\/h3>\n

    Component count matters big time. A board with 500 parts takes way longer than one with 150 parts, even on the same machine. Placement density adds another layer. When components are packed tight, your machine needs more nozzle changes, more vision checks, and more careful feeder positioning.<\/p>\n

    Feeder layout creates delays too. If your board uses 40 different component types, your machine spends time switching between them instead of placing. Fine-pitch components like 0201s or 01005s need slower placement speeds for accuracy. BGA and QFN parts add their own challenges with alignment and handling.<\/p>\n

    PCB panelization changes the math as well. Larger panels mean more handling time and sometimes reduced placement speed because the machine has to reach further.<\/p>\n

    Most manufacturers rate their machines using simpler benchmarks. IPC9850 tests use standard board configurations that don’t match real mixed assemblies. That’s why many teams de-rate by 20-30% to get realistic numbers. Practical output often lands in the 35,000-75,000 CPH range instead of the headline figure.<\/p>\n

    Practical Boards Per Hour Formula<\/h3>\n
    Boards per Hour = (3600 \/ Actual Board Cycle Time in seconds) \u00d7 First Pass Yield\n<\/code><\/pre>\n
    This gives you actual good output, not just boards that need rework.<\/p>\n
    | Variable | Theoretical Value | Practical Value | Why the Gap |
    \n|———-|——————-|—————–|————-|
    \n| Machine CPH | 80,000 | 50,000-65,000 | Vision cycles, feeder delays |
    \n| Board complexity | Simple benchmark | Mixed packages | More nozzle changes |
    \n| Changeover time | Minimal | 3-5 minutes | Feeder replenishment |
    \n| Inspection queue | None | Up to 68 sec\/board | AOI bottleneck |<\/p>\n
    Measure your actual board cycle time first. Then multiply by your validated first-pass yield. That’s your real throughput number.## Balance Reflow Throughput With Thermal Profile Stability<\/p>\n
    Here’s something that catches a lot of teams off guard. Your reflow oven is often the station that actually limits how fast your whole line can run, even when it doesn’t have the slowest spec sheet number.<\/p>\n
    Why? Because lead-free soldering profile requirements mean your conveyor speed can’t just be cranked up. You’ve got to stay within thermal limits.<\/p>\n
    The IPC\/JEDEC J-STD-020 standard sets the boundaries. We’re talking about preheat zones around 150-200\u00b0C, a ramp rate that stays at or below 3\u00b0C per second, time above the 217\u00b0C liquidus point somewhere between 60-150 seconds, peak temperatures typically landing around 235-245\u00b0C, and cooling rates kept to 6\u00b0C per second or less.<\/p>\n
    Push the conveyor too fast and those numbers shift. Boards don’t soak long enough. Flux doesn’t activate properly. You get cold solder joints, tombstoning, and insufficient wetting. For BGA and QFN components, the stakes are even higher. Uneven thermal profiles create voiding issues and head-in-pillow defects that can pass AOI but fail in the field.<\/p>\n
    I worked with a team last year that learned this the hard way. They pushed their conveyor speed up by 15% to hit a throughput target. Within two shifts, their void rates climbed from under 8% to over 20% on BGA packages. Some boards failed field testing. They spent three weeks slowing back down, re-profiling each zone, and testing until they found a stable operating window.<\/p>\n
    Now they run about 480 boards per hour, and their profiles stay consistent shift to shift.<\/p>\n
    \"Engineer<\/figure>\n<\/p>\n
    Your Optimization Levers<\/h3>\n
    Zone temperature tuning is usually the first place to look. Adjusting heater outputs in the preheat and soak zones lets you compensate for speed changes without sacrificing thermal balance.<\/p>\n
    Board spacing control matters too. Running boards too close together means they share heat in the reflow zone, which throws off your profile. Most manufacturers recommend a minimum gap based on panel size and oven length. Check your equipment documentation and test it with actual product.<\/p>\n
    Nitrogen environments help when you’re running lead-free alloys, because they reduce oxidation and improve wetting at lower peak temperatures. This gives you more room to optimize speed without overheating components.<\/p>\n
    Profile verification has to become part of your routine. Run thermocouple boards regularly, especially when you change product families or adjust speeds. A thermal profile that worked for one board might not work for another with different mass or component density.<\/p>\n
    \n
    Pro Insight:<\/strong> Before changing conveyor speed on your reflow oven, run a thermocouple profile on a representative board and check your time-above-liquidus and peak temperature against the component limits. A 10% speed increase can shift your TAL by 15-20 seconds, which is enough to cause defects on sensitive packages like BGAs and QFNs. Measure first, then adjust.<\/p>\n<\/blockquote>\n
    The goal isn’t to run the oven as fast as possible. It’s to find the speed that maximizes throughput while keeping your profile within limits and your defects at acceptable levels. That sweet spot usually takes a few iterations to find, but once you do, your quality numbers stay stable even as you optimize the rest of the line around it.## Prevent Inspection and Quality Control From Becoming the Bottleneck<\/p>\n
    Here’s something nobody talks about enough. You speed up your line to hit higher throughput numbers, but then your inspection station chokes. Boards pile up waiting for SPI review. AOI queues grow. Manual defect disposition takes forever. Suddenly your “faster” line is bottlenecked by quality control.<\/p>\n
    This happens more than you’d think.<\/p>\n
    SPI usually runs fast, but when it flags a board, someone has to review it. That review queue can eat 2-5 minutes per batch depending on your process. AOI takes 10-20 seconds per board in real production. AXI for hidden joints like BGAs and QFNs? Often 30-60 seconds per board because X-ray imaging is slow.<\/p>\n
    \"Engineer<\/figure>\n<\/p>\n
    False calls make this worse. Siemens data shows AOI false-call rates can hit 5-70% of passing throughput, and up to 95% of those alarms turn out to be nothing. That means your operators spend most of their time clearing boards that were never bad in the first place.<\/p>\n
    The rework loop is the killer too. When a board fails inspection and waits for disposition, it sits in queue. That WIP builds up fast on high-speed lines, and now you’ve got boards cooling down or getting handled while they wait. Quality suffers. Throughput drops.<\/p>\n
    So here’s what actually works. Tune your AOI programming to your board types. Newer AI-assisted systems cut false calls by 50-90% compared to older rule-based programming. Size your inspection capacity to match your real line speed, not the spec sheet number. And make sure your defect disposition process has clear ownership so boards don’t sit waiting for decisions.<\/p>\n
    \n
    Pro Insight:<\/strong> Run a false-call audit before you speed anything up. If your AOI is flagging 30% of boards unnecessarily, faster upstream speeds will just create a bigger inspection pileup. Fix the programming first, then optimize line speed.<\/p>\n<\/blockquote>\n
    The goal is simple. Your inspection station should keep pace with production without creating WIP, and your defect data should drive process improvements, not just catch bad boards.## Use Buffers, Conveyors, and Automation Without Hiding Process Problems<\/p>\n
    Buffers feel like a quick fix. They’re not always the answer though.<\/p>\n
    Short cycle-time gaps between stations? Buffers help there. They absorb variation so faster machines don’t constantly stop waiting for slower ones. But when a station is genuinely slower than its neighbors, buffers just hide the problem. WIP builds up. Boards sit and maybe cool down too much. Quality drifts. And nobody notices until defect rates climb.<\/p>\n
    Here’s how to tell which situation you’re dealing with:<\/p>\n
    | Situation | Buffer Appropriate? | Fix Root Cause? |
    \n|———–|———————|—————–|
    \n| Minor speed variation (under 30 sec) | Yes | No |
    \n| Station consistently slower than neighbors | No | Yes |
    \n| Inspection queue building daily | No | Yes |
    \n| Occasional feeder replenishment delay | Yes | No |<\/p>\n
    When buffers make sense, make sure your conveyors match your board size. SMEMA and Hermes protocols handle the handshake between machines. Boards need consistent spacing, and handling stability matters, especially for panelized assemblies. Dropped boards create scrap fast.<\/p>\n
    \n
    From Our Experience:<\/strong> After equipment upgrades or new product introduction, measure baseline performance for at least two weeks before adding buffers or changing speeds. Most teams skip this step and end up chasing problems they created themselves.<\/p>\n<\/blockquote>\n
    Automation helps too. Auto-loaders and unloaders cut labor cost on high-volume runs. Magazine handlers reduce feeder changeover time. Material tracking systems catch shortages before they stop the line. These investments pay back fastest when your line is already balanced, not when you’re using them to compensate for a hidden bottleneck.<\/p>\n
    The decision comes down to this: buffers smooth flow; they don’t fix flow. If your bottleneck station needs help, address that station directly rather than papering over it with accumulation.## Optimize for Defect-Free Throughput, Especially With BGA and QFN Assemblies<\/p>\n
    Here’s a hard truth that hits every high-volume SMT operation eventually. Your line can churn out 500 boards per hour and still lose money if half of them need rework. Raw throughput means nothing if your defect rate eats up the gains.<\/p>\n
    Effective throughput is what actually matters. That’s boards that pass final test, get routed to the customer, and don’t come back.<\/p>\n
    Speed changes affect solder quality more than most teams realize. Push your conveyor faster and your thermal profile shifts. Components see different soak times. Flux doesn’t activate properly. The result is a list of defects that range from annoying to catastrophic.<\/p>\n
    | Defect Type | Why Speed Often Causes It | What To Do |
    \n|————-|—————————|————|
    \n| Bridging | Too much paste or too fast ramp spreads solder | Check paste volume with SPI, slow ramp rate |
    \n| Insufficient solder | TAL too short, paste didn’t melt fully | Increase conveyor dwell time, lower peak temp slightly |
    \n| Voiding | Uneven heating creates gas pockets | Balance zone temps, ensure proper preheat |
    \n| Opens | Cold joint from insufficient liquidus time | Verify TAL against paste datasheet |
    \n| Tombstoning | Uneven wetting forces component to stand up | Check component placement accuracy and paste print |
    \n| Component shift | Reflow movement before paste fully solidifies | Adjust cooling rate, verify board support |
    \n| BGA head-in-pillow | Thermal inconsistency during reflow | Profile entire board for mass variation |<\/p>\n
    I remember a specific situation with a BGA package on an automotive control module. The line was running smoothly until someone bumped the conveyor speed up 12% to clear a backlog. Within a few hours, field returns started coming in. X-ray inspection showed head-in-pillow defects that AOI couldn’t catch. The joints looked fine on the surface. They failed under thermal cycling in the customer’s car.<\/p>\n
    That repair effort cost more than two weeks of the productivity gain they thought they were making.<\/p>\n
    For automotive, aerospace, and military electronics, these defects aren’t just expensive. They can be dangerous. That’s why industries with strict reliability requirements need process controls that protect against speed-induced defects, not just speed that chases a throughput number on a screen.<\/p>\n
    The best SMT operations in 2026 run thermal profiles as a standard part of every shift, not just when something goes wrong. They match their line speed to their process window, not the other way around. And they measure success in defect-free boards per hour, not just boards per hour.<\/p>\n
    \n
    From Our Experience:<\/strong> After any equipment upgrade or new product introduction, run at least 200 boards through full inspection before trusting your defect rate numbers. Initial runs always have higher escape rates, and speed optimization on unproven processes creates problems you’ll discover in the field, not in your factory.<\/p>\n<\/blockquote>\n
    When you’re working with BGA and QFN packages, that goes double. Those components hide their defects well and reveal them at the worst possible time.## Build a Repeatable Line-Speed Optimization Workflow<\/p>\n
    Here’s the thing. You can measure your bottleneck once and make a change. But without a repeatable process, that improvement fades. Equipment wears in. Products change. Someone adjusts a setting and nobody tracks it. Before you know it, you’re back to chasing throughput numbers that don’t match reality.<\/p>\n
    A structured workflow fixes that. Here’s the sequence that actually works.<\/p>\n
    The Seven-Step Optimization Cycle<\/h3>\n
    | Step | Action | What You’re Looking For |
    \n|——|——–|————————|
    \n| 1 | Baseline current output | Real boards per hour, not spec sheet numbers |
    \n| 2 | Identify the true constraint | Measure cycle time at every station over a full shift |
    \n| 3 | Model target takt time | Divide available time by customer demand |
    \n| 4 | Adjust one variable at a time | Change speed on the constraint station only |
    \n| 5 | Validate thermal and inspection quality | Run thermocouple profiles and check defect rates |
    \n| 6 | Monitor over several shifts | Watch for drift, not just day-one results |
    \n| 7 | Lock in and document settings | Update recipes, SOPs, and training materials |<\/p>\n
    KPIs You Need to Track<\/h3>\n
    Don’t just watch one number. These work together:<\/p>\n
      \n
    • Boards per hour<\/strong> – your real output rate<\/li>\n
    • First-pass yield<\/strong> – boards passing inspection without rework<\/li>\n
    • Line utilization<\/strong> – how much time each station is actually working<\/li>\n
    • Downtime<\/strong> – unplanned stops, changeovers, material handling<\/li>\n
    • WIP levels<\/strong> – boards sitting between stations<\/li>\n
    • Rework rate<\/strong> – defective boards being reworked<\/li>\n
    • OEE<\/strong> – overall equipment effectiveness (availability times performance times quality)<\/li>\n<\/ul>\n
      Most SMT lines in 2026 run OEE between 50-75%. If you’re below 60%, there’s usually low-hanging fruit in availability or quality losses. Tracking these metrics together tells you whether speed gains are real or just shifting problems around.<\/p>\n
      When To Re-Run the Workflow<\/h3>\n
      This isn’t a one-time thing. Reset your baseline and repeat the cycle when:<\/p>\n
        \n
      • New product introduction hits the line<\/li>\n
      • Equipment upgrades or replacements happen<\/li>\n
      • Lead-free profile requirements change<\/li>\n
      • You see defect rates climbing for any reason<\/li>\n
      • Customer demand shifts significantly<\/li>\n<\/ul>\n
        The workflow itself doesn’t change. What changes is where your constraint sits and what your takt time needs to be.<\/p>\n
        \n
        From Our Experience:<\/strong> After equipment upgrades or new product introduction, measure baseline performance for at least two weeks before adding buffers or changing speeds. Most teams skip this step and end up chasing problems they created themselves.<\/p>\n<\/blockquote>\n
        That two-week minimum gives you enough data to separate normal variation from real problems. Rush it and you’ll optimize to the wrong numbers.## When Equipment Upgrades Are the Right Throughput Decision<\/p>\n
        Sometimes tuning just isn’t enough anymore. Your line hits a wall where process tweaks stop moving the needle. That’s when you need to think about equipment upgrades.<\/p>\n
        Signs You Need an Upgrade<\/strong><\/p>\n
        How do you know when it’s time to spend capital instead of time on optimization? Watch for these signals: chronic bottlenecks that shift from station to station without staying fixed, lead-free profile constraints that force you to choose between speed and compliance, defect rates climbing despite better programming, outdated protocols that don’t talk to newer machines, and operators spending hours on tasks that should be automated.<\/p>\n
        Upgrade Paths Worth Considering<\/strong><\/p>\n
        Higher-capacity reflow ovens give you more thermal headroom for speed. Complete SMT production lines sync everything from the start. Wave soldering machines handle through-hole work without slowing your surface-mount flow. Automation-compatible conveyors reduce manual handling and WIP.<\/p>\n
        Buying Smart in 2026<\/strong><\/p>\n
        Don’t chase speed ratings. Buy for total good output, reliability, compatibility with existing protocols like Hermes, and lifecycle support from your vendor.<\/p>\n
        | Consideration | Tuning | Partial Upgrade | Full Line |
        \n|—————|——–|—————-|———–|
        \n| Cost | Low | Medium | High |
        \n| Throughput gain | 5-15% | 15-40% | 40-100%+ |
        \n| Integration risk | None | Low | Medium-High |
        \n| Best for | Stable products | One bottleneck | Major expansion |<\/p>\n
        The goal is straightforward. Match your investment to your actual constraint, not the spec sheet promise.## Expert Takeaway: Increase Throughput Only When the Whole SMT Line Can Sustain It<\/p>\n
        Here’s the bottom line after walking through all of this. SMT throughput optimization isn’t about pushing any single machine to its rated speed. It’s about understanding your true constraint, measuring your real output, and making sure every station works together without creating defects.<\/p>\n
        Reflow stability matters as much as placement speed. Inspection capacity has to keep pace with production or you’ll build up WIP that kills quality. And defect reduction, especially for BGA and QFN packages, has to stay front and center, because rework costs can wipe out any productivity gains you make.<\/p>\n
        Your Action Checklist Before Changing Any Speeds:<\/strong><\/p>\n
          \n
        • Time actual cycle time at every station, not just the spec sheet numbers<\/li>\n
        • Verify your thermal profile still meets IPC\/JEDEC limits after any speed change<\/li>\n
        • Check your inspection queue for false calls and bottlenecks<\/li>\n

          Faster machines don’t always mean faster lines. In SMT manufacturing, speeding up one station often just shifts the bottleneck downstream, creating quality problems and hidden rework costs. This article reveals a practical framework for identifying your true constraint, balancing thermal profiles, and optimizing the whole production line for defect-free output instead of just chasing headline speed ratings.<\/p>","protected":false},"author":1,"featured_media":5233,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"categories":[1],"tags":[],"class_list":["post-5256","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-company-news"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/posts\/5256","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/comments?post=5256"}],"version-history":[{"count":0,"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/posts\/5256\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/media\/5233"}],"wp:attachment":[{"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/media?parent=5256"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/categories?post=5256"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.chuxin-smt.com\/sr\/wp-json\/wp\/v2\/tags?post=5256"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
