Study Of Wave Soldering Using Thermal-Fluid Structure Interaction Technique On Pin Through Hole In Printed Circuit Board

Wave soldering is one of the most familiar and well-established processes in the electronics assembly industry, which is used to assemble the pin-through hole (PTH) component onto the printed circuit board (PCB). The solder joint defects such as cracks, void formation, and incomplete filling of the...
