LSI (semiconductor) Test System BOST Series


What is BOST(Build Out Self Test)?

It is the test method for supporting measurement of DUT with a performance board of LSI tester.

Advantage of YDK's BOST

With External power supply and control PC, the unit can be used as ultra-small LSI tester. So it has concept that the unit can cope with producing small number with many kind of devices. For the purpose of being able to maintain easily by worker in production line when fault is occurred, each area for function is located on subordinate board. So there is consideration for the worker to be able to change only the parts when fault is occurred in the unit.
