SMT/Multilayer board/Dip/Oem pcba/FR-4/Kerongda/Smt Control Board
SMT patch processing
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.
After all the above processes are completed, QA will conduct a comprehensive test to ensure product quality.
SMT basic process elements include: screen printing (or dispensing), mounting (curing), reflow soldering, cleaning, testing, repair
1. Screen printing: Its function is to leak solder paste or patch glue onto the PCB pad to prepare for the welding of components. The equipment used is screen printing machine (screen printing machine), located at the front end of the SMT line.
2, dispensing: it is to drop the glue to the fixed position of the PCB board, its main role is to fix the components to the PCB board. The equipment used is the dispensing machine, which is located at the front end of the SMT production line or behind the testing equipment.
DIP
1,The process of DIP processing is: putting in the hole →AOI→ wave soldering → cutting pin →AOI→ correction → washing → quality inspection.
2,After wave soldering, The products will be will scanned by AOI equipment to ensure that no error occurs.
