12Layer HDI PCBs for Burn in boards and semiconductor Test boards / thin board
Burn-in is an accepted practice for detecting early failures in a population of semiconductor devices. It usually requires the electrical testing of a product, using an expected operating electrical cycle (extreme of operating condition), typically over a time period of 48-168 hours. Alternatively, thermal (e.g. 125°C for 168 hours) or environmental stress screening (e.g. 20 cycles from -10 to 70°C ramped at +°C/mm) is used. Burn-in is applied to products as they are made, to detect early failures caused by faults in manufacturing practice.
1 . Descriptions:
What is a BIB ?
A burn-in board is a printed circuit board that is used in the burn-in process. The components added to the board are stressed using extreme heat to highlight any failures. Once the stress tests have been completed engineers will analyse the results to make sure everything is working within the correct parameters.
