High Reliability Soldering
Solder is the glue that holds electronic circuits together. It provides both a physical attachment between components and a conductive bond that permits current flow. Solder consists of an alloy of lead and tin that has low mechanical strength. It’s prone to work hardening from vibration and temperature fluctuations over time, leading to intermittent operation and eventual failure. To achieve maximum service life from a device, it’s necessary to establish consistent soldering habits that produce high reliability joints. The inspection process is primarily visual. In order to detect a bad solder joint, it’s essential to understand what goes into producing a good one first.
