Abstract

The flexible circuit board has several joints and several test pads corresponding to and electrically insulated from the joints separately. After the joints of the flexible circuit board are connected to the pins of display, the test pads are connected electrically to the joints via the pins in the display, so that the measurement via the test pads can judge the connection quality between the flexible circuit board and the display.

Description

technical field [0001] The present invention relates to a method for testing the joint pass rate of a flexible circuit board and the structure of the flexible circuit board, in particular to a method for testing the joint pass rate between a flexible circuit board and a display and a flexible circuit with a test pad plate. Background technique [0002] Usually, after the flat panel display is fabricated, the flat panel display is connected to an external system to supply power or drive the display of the flat panel display. The general method for connecting the flat panel display to the external system is to press the flexible circuit board on the edge of the flat display panel so that the circuits of the flat panel display and the flexible circuit board are connected to each other. Since the other end of the flexible circuit board is connected to the external system, the flat panel display can be connected to the external system through the connection of the flexible circu...
