The text introduced the test method and application in some special instances about Information technology equipment Protective Bonding Conductor in Type test and Routing test.
The wire bonding failure of devices is mainly shown as the breaking off of wire bonded on the packages after temperature test, and the failure causes are related to wire bonding process and materials.
