Abstract
A failure analysis system (900) for printed circuit board (600) includes testing equipment (100) and a monitor (200). The testing equipment includes a base (120), a fixing body (180), a supporting arm (140) and a micrometer (160). The fixing body and the supporting arm are both firmly fixed on the base. The printed circuit board is fastened to the fixing body. The micrometer is slidingly attached to the supporting arm. The micrometer has a pin (1612) at one end thereof for resisting one end of the printed circuit board. The monitor electronically connects with the printed board for receiving signals from the printed circuit board. When the pin of the micrometer reaches a certain position, the signal transmitted to the monitor is broken.
