Abstract
High-density probing is a main trend of the test technology. The warping issues of probe card are caused by the high-density test. The metal backer and patches are applied to solve this problem and the optimized sizes of backer and patches are decided by the proposed flow. Using the probe card with optimized backer and patches, the stability of test can be ensured and the test yields are increased. 26.56% test-yield improvement can be obtained.
