Summary
This technical report details the Pin-in-Paste (PiP) assembly process for soldering through-hole components in printed circuit boards (PCBs). It outlines the decline of through-hole components in modern electronics, while emphasizing their performance advantages and the cost-effectiveness of the PiP method. The report describes various considerations for implementing PiP, including component verification, lead-to-hole ratios, and solder paste volume requirements. It also discusses stencil design for solder paste application and the importance of solder paste selection, focusing on properties such as hot slump performance and wetting characteristics. Additionally, the report addresses reflow considerations and quality assessment criteria, specifically referencing IPC-610 standards. The conclusion highlights the ongoing relevance of through-hole components and the benefits of adopting PiP in PCB assembly, including reduced operational costs and simplified production processes.
