SMT
SMT patch processing will purchase components according to BOM, BOM provided by customers and confirm the PMC plan of production. After the preparatory work is completed, we will start SMT programming, manufacture laser steel mesh and solder paste printing according to the SMT process.
The components will be mounted on the circuit board through SMT mounter, and online AOI automatic optical detection will be carried out if necessary. After testing, the perfect reflow furnace temperature curve is set to let the circuit board flow through reflow welding.
After the necessary IPQC inspection, the DIP material can then be passed through the circuit board using the DIP process and then through wave soldering. Then it is time to carry out the necessary post-furnace process.
