Solder insufficient
WebINSUFFICIENT SOLDER. Insufficient solder is an indicator of improper process control, and may result in reduced reliability. In this example, there is no side or heel fillet. NASA-STD … WebA joint that has an insufficient amount of solder is a solder-starved joint. Such a joint lacks the strength to perform its intended function and can lead to board failure if not addressed. Even though an insufficient solder joint may exhibit good conductivity, the board would still not be safe to use until the issue is resolved by adding more solder to the affected joint.
