Abstract: A fixture for connecting a printed wiring assembly (PWA) to an acceleration table for subjecting the PWA to highly accelerated stress screen (HASS) testing. The fixture comprises a member and multiple spacers. First openings extend through the member for receiving fasteners to connect the member to the acceleration table such that the member is spaced from the acceleration table. Second openings extend into the member for receiving fasteners to connect the PWA to the member. A third opening extends through the member to expose a substantial portion of a surface of the PWA. Also disclosed is a method comprising selecting a PWA for HASS testing, determining which one of a plurality of predetermined PWA categories includes the selected PWA, and conducting the HASS test on the selected PWA utilizing HASS testing parameters associated with the determined PWA category.
