ABSTRACT:
A SIM contact position tester (100) for verifying the position of SIM card contacts (c1-c8). A printed wiring board (102) is provided with traces (A-D) which correspond to the contacts (c1-c8) of the SIM card reader connector (101) and are configured to mate with the contacts of the SIM card reader connector (101) mounted within the radio telephone. A plurality of light emitting diodes (LED) (106) are coupled to the traces (A-D). The light emitting diodes (106) are configured to provide an indication of the position of the contacts (c1-c8) when the PWB (102) is positioned within the radio telephone. In one embodiment, the LEDs (106) sequentially light up as the printed wiring board (106) is moved into position over the contacts (c1-c8) of the SIM card reader connector (101).
