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

5 Key PCB Layout Considerations for Efficient Circuit Board Assembly and Soldering Production Processes

When designing a PCB layout, various questions inevitably arise. Is this PCB best suited for a single-layer, double-layer, or multi-layer configuration? How should you protect against ESD/EMI? Will the printed circuit board assembly (PCBA) use a single-sided or double-sided process? … Continue reading
