Manufacturability and reliability assessments were performed with a PWB Test Vehicle (RTV) utilizing a variety of surface mount components, as listed in Table 42. The test vehicle is shown in Figure 30. An imidazole-finished copper surface was used on the PWB and the component leads were hot-solder-dipped in the same alloy as the paste used for assembly. Thermal cycling was performed from —55 to 160°C with a ramp rate of 10°C/min and temperature dwell of 10 min at each end of the cycle, for a total cycle duration of 1 hr. For each alloy, approximately 27 boards each containing 28 components were tested. [Pg.718]
