What is an SMT Reflow Carrier? Why is it sometimes necessary in SMT production? And when do we need an SMT Full Process Carrier? Are there situations where neither is required?
The so-called “SMT reflow carriers or reflow templates” are essentially trays or carriers used to hold PCB (Printed Circuit Board) during the reflow soldering process. These carriers often feature positioning pillars to secure the PCB, preventing misalignment or deformation. Some advanced carriers even come with a lid, typically designed for Flexible Printed Circuit (FPC) use to avoid it from floating or lifting, equipped with magnets on both the upper and lower carriers acting as suction cups to firmly hold the board. This ensures the prevention of board deformation. In the case of rigid PCBs, a cover plate may also be used to secure specific components during the reflow process, preventing sliding.
