Abstract:
1. A method of testing a portable computing device comprising: generating one of a time domain reflectometry (TDR) measurement or a swept frequency impedance measurement of a weld joint on a gold unit using a vector network analyzer (VNA); generating one of a TDR measurement or a swept frequency impedance measurement of a weld joint between two components of a device under test using a probe coupled to the vector network analyzer wherein the vector network analyzer sends a signal to the probe that is transmitted through the weld joint; comparing the TDR measurement of the weld joint on the gold unit to the TDR measurement of the weld joint on the device under test or the swept frequency impedance measurement on the gold unit to the swept frequency impedance measurement of the weld joint on the device under test; and based upon the comparison, accepting or rejecting the weld joint on the device under test.
