Abstract:
1. A method for testing a flexible printed circuit (FPC) bonding yield, comprising: providing a flexible printed circuit having a plurality of bonding pads thereon; disposing a plurality of testing pads on the flexible printed circuit, wherein each of the testing pads is disposed corresponding to each of the bonding pads, and the testing pads are electrically isolated from the bonding pads; providing a liquid crystal display having a plurality of pins thereon; performing a bonding process, so that each of the bonding pads and the corresponding testing pad of the flexible printed circuit are electrically connected to the same pin of the liquid crystal display; inputting a testing signal into the flexible printed circuit; and measuring an output signal from the testing pads, so as to determine the bonding yield between the flexible printed circuit and the liquid crystal display.
