0.25pitch 8Layer HDI PCBs for Burn in boards and semiconductor Test boards / thin board
Burn-in is the testing of a PCB to detect early failures and establish load capacity. This is often done by running a power supply and firmware through the electronics for 12 to 48 hours. This testing process is intended to outline possible defects by running products at elevated voltage levels, outside standard temperature ranges, and under power cycling conditions.
The burn-in process enables the detection of components that will fail not only because of a specific physical defect but also because of a more general failure that occurred during assembly. The motive is to identify and replace failed components during the initial phase of the burn-in testing.
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.
