What are the quality control points in the PCBA SMT?
How does the PCBA processing factory control the quality during the production process? What quality control points are there? Note the following points:
1. During the production of the smt technology workshop, the SMT process is carried out on the PCB. The printing of solder paste and the systematic quality control details of the reflow soldering temperature control in the SMT process are important points in the PCBA manufacturing process. Facing the printing of special and complex high-tech and high-precision PCB, it is based on the laser steel mesh used in the specific SMT chip processing and production to meet the quality standards of PCB.
In addition, the technicians in the smt technical workshop must strictly follow the standard to perform the AOI test, which can effectively reduce the occurrence of defective products caused by human factors in the PCBA processing and production process of the patch processing plant.
2. The post-welding link of DIP plug-in for pcba board, this link is a very important link in the pcba processing stage of PCB, and it is the last process of patching the PCBA in the smt technology workshop to complete the patch processing ;During the post-soldering process of the DIP plug-in, the requirements and standards for the wave soldering and furnace fixtures of the pcba board are also very critical. Soldering defects such as tin and tin deficiency occur.
3. The staff of the patch processing factory conducts testing and program firing on the finished PCBA. The manufacturability report is after the patch processing factory receives the customer's production contract, before the PCBA circuit board patch processing An evaluation step will be carried out before the entire production. In the previous DFM report, the relevant person in charge of the patch processing factory will also communicate with the customer before PCBA patch processing and provide some effective suggestions. . When conditions permit, you can communicate with the customer to provide the back-end program, and then burn the program of the PCBA circuit board into the IC of the core main control through the burner; The board is tested to facilitate the integrity test and inspection of the entire processed PCBA.
BQC is a PCBA processing factory with labor and materials. We are familiar with the complete PCBA processing process and strictly control the SMT, DIP and PCBA burning test links to ensure that every production link is guaranteed in quality and quantity, giving customers the best product.
