What factors affect the peak welding quality of PCBA?
The quality of wave soldering PCBA board is not always judged from the surface phenomenon of PCB board during soldering High quality PCB boards should be analyzed and judged from the design source to the overall packaging and delivery, and then find out the causes to avoid undesirable phenomena Next, based on the rich experience of kingford, what factors affect the peak welding quality of PCBA?
Polychlorinated biphenyls
The factors that affect the peak welding quality of PCBA during PCB processing are as follows:
PCB board is composed of several electronic components arranged and assembled on PCB board by PCB factory designers according to predetermined scientific and technological requirements through wiring and installation design. In the arrangement and assembly, the designer must abide by the technical constraints of PCBA peak welding and shall not act on his own. Hundreds of electronic components are arranged and combined, and then different metals are connected together by brazing. A large number of welded joints need to be welded simultaneously in a few seconds. At this time, the body metal must be solderable and fast solderable. The designer of the PCB manufacturer must select solderable data when designing PCB boards.

PCBA processing plants apply solder PCB on the welding surface, which helps to improve the wettability of solder on the welding metal PCB Effective practice has proved that the strength and reliability of the welded joint PCBA processing operation in SMT chip factory of PCB circuit board completely depends on the good wettability of solder to the welding metal. Therefore, the selection of solder and solder with excellent performance in surface mount technology is one of the factors that can not be ignored that directly affect the wettability effect
Temperature, time and pressure conditions are also key factors in the metallurgical process of PCBA solder joints in PCBA plant. In this case, the SMT process workshop equipment of PCB manufacturers can maintain good peak welding equipment and reasonable process parameter selection and control, which is the basis for ensuring temperature, time and pressure conditions. Only when the above requirements are fully considered, the peak welding process quality of PCBA can achieve good results.
