PCBA is PCB Assembly, Laser packing PCBA refers to the method of forming PCBA welding joint after filling in the specific PCBA welding materials in advance in the weld with laser melting or in laser. Compared with non wire filling PCBA welding, laser welding PCBA has the following advantages:
1. Avoid the strict requirement about workpiece processing and assembly.
2. It can be achieved Printed Circuit Board Assembly welding thicker and larger wokpiece with a smaller power.
3. It can control the welding tissue property by changing the filament composition.
