By S&M SMT Engineering Team
If you manage CapEx for SMT lines, you don’t need another feature brochure—you need the exact questions that de‑risk delivery, acceptance, and service. This FAQ follows the procurement flow (Technical Evaluation → Commercial Negotiation → Acceptance) and anchors answers to standards and verifiable practices.
About this checklist (scope & method): This RFQ checklist is built from recurring failure points we see in global SMT line procurement—handoff/integration gaps, ambiguous acceptance criteria, and under-defined service responsibilities. Each section turns those risks into buyer-side requirements: (1) witnessable FAT/SAT scripts, (2) contract-ready clauses for delivery, SLAs, and spares, and (3) an evidence pack you can retain for audits. It’s written for CapEx-driven line purchases (printer/placement/reflow/wave/conveyors and inline inspection) where interoperability (Hermes/CFX) and serviceability matter. Where hard service numbers aren’t publicly published, targets are presented as negotiation starters and should be validated in your contract.
Why you can trust the perspective: S&M Co.Ltd has been building SMT equipment and line solutions since 2000, with an engineering team drawing on 20+ years of field commissioning and after-sales troubleshooting experience across multi-equipment SMT lines. The team routinely supports FAT/SAT readiness (test scripts, documentation packs, punch-list closure) and line connectivity validation (Hermes board handoff and IPC-CFX/IPC-2591 event flows). Content is anchored to primary standards and publicly verifiable references (IPC, ICC Incoterms), with internal “Learn more” links used only for deeper process context.
Key takeaways
Treat the SMT equipment China RFQ checklist as three phases: define tests in FAT/SAT, lock delivery terms and SLAs in contract, and verify on arrival with evidence.
Specify Hermes and CFX versions and test handshakes during FAT; require SAT proof to your MES/traceability before sign‑off.
Use Incoterms 2020 to nail risk transfer and plan buffers around Lunar New Year and Golden Week.
Write response/dispatch windows as SLA negotiation starters (remote triage and on‑site support) and bind critical spare‑parts ship times.
Acceptance isn’t a demo; it’s a script with pass/fail criteria, logs, and sign‑offs that survive an audit.
How this FAQ is organized

Each question starts with a direct answer, then gives practical verification steps, contract language you can adapt, and one or two canonical sources. When a topic needs deeper process context, you’ll see a short “Learn more” link.
Technical Evaluation — questions to shape your SMT equipment China RFQ checklist
What belongs in FAT vs. SAT for SMT lines?
Quick answer: Prove functionality and connectivity at the vendor (FAT); re‑prove performance, utilities, and integration at your site (SAT) using scripted tests and sign‑offs.
What to verify and how: At FAT, include documentation pack review, safety interlocks, conveyor handshakes, recipe/software checks, and a representative placement/reflow exercise. On site (SAT), re‑check I/O and utilities, re‑profile the reflow oven on your alloy and load, validate AOI/SPI/AXI program transfers, and close the punch list with dates and owners. A concise framework distinguishing FAT and SAT is outlined by the PQE Group’s overview of commissioning and qualification, which many teams adapt from regulated industries in 2023 guidance: see the discussion of scope and documentation in the FAT/SAT breakdown in the PQE article in Commissioning & Qualification. Reference: PQE Group’s summary in “FAT and SAT” (2023) describes sequencing and documentation rigor: PQE Group FAT and SAT overview.
For workmanship and soldering acceptance anchors used during demonstration builds and SAT spot checks, teams often cite IPC standards for visual acceptability and process requirements: ANSI’s 2024 brief on IPC‑A‑610J and IPC’s releases on J‑STD‑001 explain scope and classes: see ANSI’s overview of IPC‑A‑610J (2024) ve IPC’s release on J‑revisions (2024).

How do we verify Hermes and CFX connectivity before we commit?
Quick answer: Ask suppliers to declare Hermes version/options and CFX message sets, then witness handshake and event flows during FAT; require SAT proof to your MES.
What to request and observe: For horizontal hand‑off, insist on the declared Hermes version (e.g., v1.6) and optional features like barcode handling and lane IDs; during FAT, watch the state model transitions and payloads. For vertical connectivity, require IPC‑CFX (IPC‑2591) message groups relevant to placement, inspection, and ovens and request evidence such as an IPC‑CFX Self‑Validation report or a live demo to a test broker. Primary sources: the official IPC‑HERMES‑9852 v1.6 specification and the IPC CFX program pages describing message frameworks and self‑validation.

How is remote access for diagnostics secured?
Quick answer: Use VPN‑based remote support with customer‑controlled enable/disable, role‑based access, session logging, and clear data‑ownership terms.
What to insist on: Specify encryption protocol, identity management, audit‑log retention, and a right‑to‑disconnect. One vendor with a public description of secure remote maintenance is Rehm, whose ViCON documentation shows VPN tunneling with customer‑side control and function restrictions; use this model as a benchmark when asking others for equivalent detail: see Rehm ViCON Software (VPN concept, PDF). If a supplier offers remote support but can’t document security controls, treat it as a risk and constrain permitted actions until evidence improves.
Commercial Negotiation — Delivery & Service answers you can put in the RFQ
Which Incoterms make sense for capital equipment and how do they change risk?
Quick answer: FCA, CIP/CPT, or DAP/DPU are common for containerized SMT equipment; use Incoterms 2020 to fix handoff, costs, and risk transfer in writing.
How to lock this down: State the exact rule and named place (e.g., “FCA Shanghai Terminal”) and clarify who books freight and insurance. Incoterms 2020 formalizes responsibilities and the point of risk transfer; use the International Chamber of Commerce’s materials as your canonical reference: start with ICC’s Incoterms 2020 portal. For teams preferring seller handoff to your forwarder under FCA with on‑board BL support, freight forwarders like Flexport explain practicalities; see their rationale for FCA in their knowledge base: Why ship under FCA (Flexport guide).
What are realistic service/SLA targets to include?
Quick answer: Treat numbers as negotiation starters unless a supplier publishes SLAs. Typical targets: remote triage within 2 business hours; critical on‑site within 48 hours from a regional hub; critical spares dispatched within 48 hours.
How to structure it: Define incident severities, remote response and on‑site windows, and escalation paths to management. Separate spare‑parts SLAs: list critical items with dispatch commitments from named hubs and define evidence (tracking numbers). Large vendors publicly describe tiered service and remote diagnostics but rarely publish hard numbers; that’s why you’ll propose targets and bind them contractually. For context on vendor service models and remote support capabilities (without numeric guarantees), see program pages from major manufacturers, e.g., ASMPT’s contract overview and software‑enabled remote support suites: ASMPT service contracts and software.
Which spare parts should be on site versus in a regional hub?
Quick answer: Stock Tier‑1 criticals on site (items that stop the line); keep Tier‑2 consumables in steady supply; accept Tier‑3 strategic modules from a regional hub with ship‑time commitments.
How to define tiers in your RFQ: Put belts, key sensors, feeder and nozzle spares, oven SSRs/thermocouples, and common PLC/PC I/O modules in Tier‑1. Place squeegee blades, filter sets, lubricants, and light sources in Tier‑2. Reserve heater zones/blowers, cameras, certain servo drives, and spare feeders for Tier‑3 with guaranteed dispatch windows. Tie stocking to obsolescence policies; request end‑of‑life notice periods (e.g., ≥12 months) similar to public statements by vision/inspection vendors—see an example of an EOL support commitment here: Koh Young end‑of‑life support notice.

How do we plan around Lunar New Year and Golden Week so SAT dates hold?
Quick answer: Add 1–2 weeks of buffer around Lunar New Year and Golden Week, pre‑book freight and on‑site crews, and align your SAT window with customs clearance reality.
What markets observed recently: Freight rate spikes and port/air capacity constraints recur in these windows. Freight platforms provide timely planning guidance; for example, Freightos publishes shipping timelines and weekly updates that advise locking space early and budgeting extra lead time ahead of the 2026 holiday. A current overview: Freightos Lunar New Year 2026 shipping timeline. Use those signals to sequence FAT early, split critical spares to air if needed, and write SAT dates as ranges with buffers.
Acceptance — pass on SAT without surprises
Your SAT should read like a test plan, not a marketing demo. Define pass/fail on scripted steps with evidence: signed profiles, calibration records, barcode traceability logs, and punch‑list closure targets. Workmanship acceptance can reference IPC‑A‑610J for visual criteria, while soldering process controls align with J‑STD‑001 expectations for your class of assembly.
Two compact artifacts accelerate negotiation. First, include an acceptance checklist addendum (e.g., “oven profile within target ±Δ°C on soak/peak; placement accuracy sample meets tolerance; AOI/SPI GR&R spot checks documented”). Second, embed a few RFQ/SLA clauses so legal and procurement have language ready.
Area | Example RFQ/SLA clause (adapt as needed) | Evidence or source anchor |
|---|---|---|
Remote diagnostics | Vendor provides VPN‑based remote support with customer‑controlled enable/disable; role‑based access; session logs retained 12 months; no data exfiltration without written consent; buyer retains data ownership. | Modeled on secure remote concepts in Rehm ViCON Software PDF |
Response times | Production‑stopping incident: remote triage ≤ 2 business hours; critical on‑site ≤ 48 hours from regional hub; written escalation matrix with named contacts. | Negotiation starter; validate in contract |
Critical spares | Supplier ships Tier‑1 criticals ex‑regional hub ≤ 48 hours; maintains published hub stock list; provides ≥12‑month obsolescence notice. | Best practice; EOL notice example: Koh Young EOL |
Hermes/CFX | Supplier declares Hermes vX.Y features and CFX message groups; demonstrates handshake and event messages during FAT; repeats to buyer’s MES on SAT. | IPC‑HERMES‑9852 v1.6; IPC CFX |
Incoterms | Delivery under FCA [Named Terminal]; risk transfers at carrier handover; on‑board BL services per Incoterms 2020; customs roles defined. | ICC Incoterms 2020 portal |

Two anonymized delivery and service cases
Case A — High‑mix EMS crossing the Lunar New Year window
Context: A North American EMS placed a December PO for a printer–placement–reflow cell, with risk concentrated around Lunar New Year congestion. The buyer prioritized schedule attainment over mode cost.
Actions: The team front‑loaded an early FAT with remote witness, declared FCA Shanghai Terminal to keep forwarder control, pre‑booked ocean for tools and air‑freighted a Tier‑1 spares kit, and wrote SLA targets (remote triage ≤ 2 hours; on‑site ≤ 48 hours). The SAT crew calendar was blocked in advance, contingent on customs release.
Outcomes: Shipment cleared within the buffered window. SAT completed in a single workweek using pre‑approved scripts; punch‑list items (minor conveyor sensor alignment and a software license key) closed within two weeks. The buyer’s MES captured traceability events during SAT as evidence for internal audit readiness.
Case B — Regulated medical OEM with strict traceability and training scope
Context: A European medical device OEM required Class 3 workmanship and end‑to‑end traceability for placement, AOI/SPI, and reflow, plus multilingual training deliverables.
Actions: The FAT script enumerated Hermes handshake tests and CFX event validation to a sandbox broker. Remote diagnostics terms specified VPN controls and session logs. Critical spares (sensors, SSRs, nozzles) were stocked on site; heater modules and vision modules were assigned to the regional hub with dispatch commitments. Training covered operator, programming, and maintenance tracks and included maintenance checklists.
Outcomes: SAT sign‑off packaged reflow profiles, calibration records, and GR&R spot checks. The OEM’s quality team accepted the SAT dossier without rework, and the preventive maintenance cadence was embedded into the service schedule from Day 1.
Practical example — where an S&M line can support acceptance
In one SAT workflow, a nitrogen reflow oven’s oxygen sensor readouts and zone‑control stability were verified alongside in‑situ profiles and barcode events to MES. A vendor like S&M Co.Ltd can be used to demonstrate these steps neutrally: witness oxygen ppm stability while running your alloy profile, export the profile/report, and confirm Hermes board handovers and CFX events pass through to your repository.
