When companies choose PCB conveyor systems, matching conveyor features to board size and weight ensures smooth handling and prevents damage. This step supports production efficiency and quality.

Throughput and Speed

Production lines must move quickly to meet output targets. Conveyor speed controls how fast PCBs travel through assembly machines. A higher throughput rate increases the number of boards processed per hour. The following table highlights how conveyor speed affects efficiency:

Factor	Effect on PCB Assembly Efficiency
Throughput Rate	Conveyor speed directly controls how fast PCBs move through SMT machines; faster conveyors increase output, slower ones reduce it.
Component Placement Accuracy	Proper conveyor speed and design ensure PCBs are aligned correctly, preventing defects and improving quality.
PCB Warpage	Well-designed conveyors minimize mechanical stress and temperature-induced warpage, preserving PCB integrity.
Maintenance Requirements	Efficient conveyors require less frequent repairs, reducing downtime and supporting continuous production.

Note: Companies should choose PCB conveyor systems with adjustable speed settings to match the pace of their pick-and-place machines, reflow ovens, and inspection stations.

Selecting the right conveyor speed helps maintain cycle time and prevents bottlenecks. If the conveyor moves too slowly, production falls behind. If it moves too quickly, boards may misalign or suffer damage. Companies must balance speed with accuracy and reliability.

Line Layout and Space

Space planning plays a key role when companies choose PCB conveyor systems. Production lines often have limited room, so conveyors must fit within the available area without crowding other equipment. The minimum and recommended space requirements for SMT lines include:

Requirement Aspect	Minimum / Recommended Space
Transfer side width	Minimum 5.0 mm
Components/solder joints on the transfer side	None allowed on front and back edges
Non-transfer side clearance	Recommended 2.5 mm component-free area
Transmission edge size	Generally 3.5 mm or more, depending on equipment (stencil printer, SMT machine, reflow oven)

Alert: Insufficient space can lead to installation problems, maintenance difficulties, and increased risk of PCB damage.

Companies should map out their production line layout before they choose PCB conveyor systems. They must consider the footprint of each conveyor, the path of PCB travel, and the need for access during maintenance. Overhead conveyors or modular designs can help maximize space and improve workflow.

By carefully assessing PCB size and weight, throughput and speed, and line layout and space, companies can choose PCB conveyor systems that match their production needs. This approach leads to higher efficiency, better product quality, and long-term value.
