Short description

This specification defines test methods and performance criteria for ultrasonically welded wire-to-terminal bonds as shown in Figure 1. This specification subjects parts to environmental exposures to simulate a lifetime of field exposure for a road vehicle. Exposures referenced in this specification include thermal shock, temperature humidity cycling, and mechanical stress. This specification is intended to evaluate the strength and performance of the interface between wires and the electrical terminal pad. The graphics used are specific to the linear weld type of process equipment. Validation of the terminal is a separate task (refer to a component validation test such as SAE/USCAR-2).
