The consequences of cracked solder joints may include increased electrical resistance, intermittent functionality, and potential open circuits. But, when you want to see the cracks, a visual inspection is often used to identify them. Cold solder joints refer to soldering that is not fully melted due to insufficient temperature or too short a time, resulting in a rough, dull solder joint surface and unreliable connection. This lack of proper bonding can lead to various issues. Disturbed joints arise when there is movement of any kind during the cooling/solidifying of the solder. This movement can be an unstable work surface or human error which will cause the solder to become distressed before it has completely solidified.
