FAILURE ANALYSIS SYSTEM AND METHOD USING THE SAME
First Claim
1. A failure analysis system for a printed circuit board, comprising:
- a testing equipment including;
a base;
a fixing body for fastening a printed circuit board thereon;
a supporting arm being fixed on the base; and
a micrometer being slidingly attached to the supporting arm, the micrometer including a pin at one end thereof, the pin being operative to be moved in a vertical direction for resisting one end of the printed circuit board; and
a monitor being electronically connecting with the printed board for detecting signals sent from the printed circuit board when the printed circuit board has not been bent to fail;
wherein when the pin of the micrometer is operated to resist and force the printed circuit board to bend beyond a predetermined angle and fail, the monitor detects no signals sent from the printed circuit board.

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.

11. A method for analyzing failure of a printed circuit board, comprising steps of:
-
fixing an end of the printed circuit board to a fixing body, leaving other portions of the printed circuit suspended; electronically connecting the printed circuit board to a monitor which supplies power to the printed circuit board thus enabling the printed circuit board to continuously send signals and the signals are detected by the monitor; moving a pin of a micrometer to touch a second end of the printed circuit board and recording a first value of the micrometer once the pin has just touched the printed circuit board; keeping moving the pin of the micrometer to further touch the printed circuit board and bend the printed circuit board until the monitor detects no signals sent from the printed circuit board, simultaneously recording a second value of the micrometer; counting the distance of the pin moved according to the recorded first value and second value of the micrometer thereby determining a critical curve angle of the printed circuit board.
