How to Implement Paste-In-Hole (PIH) Process for Through-Hole Devices and Solve Solder Filled Percentage for PTH
The PIH (Paste-In-Hole) process involves directly printing solder paste onto the Plating Through Holes (PTHs) of a PCB (Printed Circuit Board). Subsequently, Through-Hole Devices (THDs) are inserted directly into these holes with pre-applied solder paste. At this point, some of … Continue reading
