Part of its flexible termination product lines, Kemet’s tin/lead end metallization provides flex performance and improved reliability while minimizing the risk of a catastrophic and potentially costly failure event. Automotive applications for the flexible termination system include circuits with a direct battery or power source connection, critical and safety-relevant circuits without (integrated) current limitation, as well as any application that is subject to high levels of board flexure or temperature cycling. When performance-tested, PCB test boards containing mounted devices were flexed to 10 mm (0.4 in), and crack initiations were detected by a sudden change in capacitance and then verified with destructive physical analysis for the presence of a flex crack. The minimum crack detection for the standard termination system was 4.2 vs. 6.8 mm (0.17 vs. 0.27 in) for the flexible termination system. According to Kemet, all standard termination part types failed within 8 mm (0.31 in) of board flexure, while most flexible termination system capacitors survived 10 mm (0.4 in) of board flex with no cracks or failures.
