Difference Between Wave Soldering and Manual Soldering in PCBA Processing (Part 2)

2. the high quality of wave soldering

• When wave soldering is performed, the welding parameters of each solder joint can be “tailored”, and there is enough process adjustment space to adjust the welding conditions of each solder joint, such as the amount of flux sprayed, soldering time, and soldering wave. The height and wave height are adjusted to the best, the defect rate can be greatly reduced, and it is even possible to achieve zero defect soldering of through-hole components. Compared with manual soldering, through-hole reflow soldering and traditional wave soldering, the defect rate of selective wave soldering ( DPM) is the lowest. 

• Wave soldering uses a programmable and movable small tin cylinder and a variety of flexible soldering nozzles, so it can be programmed to avoid certain fixing screws and stiffeners on the B side of the PCB during soldering. In order to avoid damage caused by contact with high temperature solder, there is no need to use custom soldering trays and other methods.

• From the comparison of wave soldering and manual soldering, we can see that wave soldering has many advantages such as good soldering quality, high efficiency, strong flexibility, low defect rate, less pollution and variety of soldering components.
