Printed circuit board inspection

Burn-in Boards

Burn-in Boards

Burn-in is a process done to components prior to regular use in which the components are stressed to detect failure and ensure component reliability.

The PCB burn-in process is usually done at 125ºC, with electrical excitation applied to the samples. The process is facilitated by using burn-in boards where the samples are loaded. These boards are then inserted into the burn-in oven which supplies the necessary voltages to the samples while maintaining the oven temperature at 125ºC. The electrical bias applied may either be static or dynamic.
