Selective Soldering

Selective soldering is the process of soldering components to circuit boards (PCB) selectively and molded modules that might be damaged by the overheating wave soldering during a traditional Surface-mount technology (SMT) or Through-hole technology assembly processes. With the growing popularity of SMT technology, through-hole technology is taking over less land on a PCB assembly. But through-hole pins are still a necessity for several boards, and they still got to be soldered.

While this process is often cumbersome, many manufacturers have turned to selective soldering as a particular and cost-effective thanks to solder through-hole technology. Hand soldering is not always accurate, also slow, and costly, but selective soldering allows soldering through-hole pins and works around delicate and sensitive SMT packages on specific areas of the board.

This promotes repeatability – and thus, fewer defects, increased throughput, and overall cost reduction. There are alternative ways to execute selective soldering, but it’s best with a programmable machine. This technology has its own set of challenges like other soldering processes. Because it [Selective Soldering] applies heat to only one place on the board. The flux contained within the solder paste won’t activate properly and can cause flux residue to spread to other parts of the board.

Ionic contaminants contained within the flux residue aren’t easily detectable, and this sort of ionic contamination could eventually cause dendritic growth later within the board’s lifecycle. A method to beat this challenge is to preheat the board before the process so that the flux can better activate. Using this method, you’ll mitigate flux migration.
