Abstract: According to the characteristics of anisotropic conductive film(ACF), a nondestructive testing fixture for RF BGA shell is designed, which can be used to test the electrical performance of RF BGA shell and devices at the same time. Through the comparative analysis of the actual test, the test results of the fixture are in good agreement with those of the conventional welding method, and have the characteristics of accurate test performance and non-destructive, which provides convenience for the electrical performance test of the shell.
