| Abstract Scope |
Modern computer-controlled flight systems depend on the integrity of soldered joints over long times under repeated vibrational loading and yet, very little mechanically loaded high-cycle fatigue data on high-reliability SnPb solder joints exists in the open literature. This talk describes our efforts to fill this gap with 12 Hz fully-reversed strain-controlled high-cycle fatigue experiments on OHFC copper butt joints with eutectic SnPb and SAC 396 solders. Joint failures occurred across a range of 100-1,000,000 cycles to failure. Efforts were made to correlate fatigue initiation sites with micro- & macro-defects.
