Cold Solder Joint: Understanding and Prevention

A cold solder joint is a defect caused by improper melting of solder to bond PCB electronic components. This defect can impact the functionality of a PCB assembly, and so must be carefully avoided. Solder Joints on Circuit Board Introduction Soldering involves bonding two metals together using a solder alloy. Metal in the solder bonds with metal on the printed circuit board (PCB) or component. During this process, the solder melts into fluid molten to adhere properly to the component for an excellent solder joint. When the solder does not melt sufficiently, it creates a series of reactions that results in solder joint failure. This defect is known as Cold […]
