The printed circuit board assembly is formed by a designer who arranges and combines multiple electronic components on the PCB through wiring and installation design according to predetermined technical requirements. When arranging and combining, the designer must abide by the constraints of the wave soldering process and cannot act on his own. For hundreds of electronic components arranged and combined, different metals can be connected with solder. A large number of welding points need to be welded at the same time within a few seconds, which requires the body metal to have the ability to be welded easily and quickly. Therefore, materials with good weldability must be selected in the design.
Heating and melting the solder is an essential part of the soldering operation. Flux is usually used on the soldering surface to promote the wetting of the solder metal by the solder. Practice has proved that the strength and reliability of solder joints depend entirely on the good wettability of the solder to the weld metal. Therefore, the selection of excellent solder and flux is a non-negligible factor that directly affects the wetting effect.
In the metallurgical process of solder joints, temperature, time and pressure conditions are the key. Therefore, the reasonable selection and control of good wave soldering equipment and process parameters are the basis for ensuring temperature, time, pressure and other conditions. Only by fully considering the above requirements, the PCB assembly wave soldering process can achieve good results.
The above are the factors that affect the quality of PCB assembly wave soldering. I hope this article can help you!
