Abstract:
1. A method for repairing and assembling contact image sensor (CIS) module, comprising following steps: (1) preparing a sensor housing having a first surface, a second surface, at least a securing post, and a plurality of receiving grooves being adapted to receive a plurality of optical elements; (2) preparing a PCB having photosensor elements, electronic elements and circuits thereon and being adapted to receive the light signals produced by the said optical elements and convert said light signals into the electrical signals, said PCB further having at least a securing hole on a predetermined position thereof; (3) assembling the PCB into the sensor housing, the securing post of the sensor housing passing through the securing hole and extending through the PCB; (4) melting the tip of the securing post and forming a fastening means for fixing the PCB to the sensor housing; (5) testing the assembled CIS module, if the module can't pass the test, then doing the following steps: (6) cutting off the fastening means and taking away the PCB for repairing or replacing; (7) cutting off the securing post located on the sensor housing; (8) preparing a adapted post having a predetermined length of securing post and fixing said adapted post to a corresponding position of the sensor housing on which the original securing post located; (9) assembling the repaired or replaced PCB into the sensor housing, and make the tip of the adapted post passing through the securing hole and extending outwardly from the PCB; (10) melting the tip of the adapted post and forming a fastening means for fixing the repaired or replaced PCB to the sensor housing; (11) testing the repaired CIS module, if need, repeat the steps from step (6) to step (11) until the CIS passes the test.
