Abstract


With the popularization and development of wireless communication technology , wireless communication chip demand is growing . At the same time , the requirements for the quality and cost of the chip is also rising . Therefore, the for the WLAN chip testing program not only need to ensure a basic level of test coverage , and more need to reduce the cost of testing to reduce the total cost of the chip . This article in Ultraflex platform by WLAN chip DC , AC , mixed-signal and radio frequency (RF) signal is part of a complete test to ensure that the basic test coverage , covering the contact test , the leakage test MBIST / SCAN / JTAG , , DACs / ADC testing and radio frequency (RF) receiver and transmitter testing. The total includes over 900 sub- test project to ensure that the chip can normal wireless communication and maintain a lower level of dynamic and static current . At the same time , the test program parallel test designed multi-position ( eight stations ) test panels to reduce the cost of testing , and by reducing the RF test portion of the test frequency to reduce the test project , thus reducing the testing time . Finally, the last amendment of the test solution through the analysis of the pre- production data and put into the production stage .
