What approach was used for board-level testing and what tests were run?
• A variety of surface mount packages were selected to cover small and large body sizes, gull-wing and J-bend lead geometries as well as land area contacts. • Lead-free parts were attached to the PCB using both SnPb and Sn3.5Ag0.7Cu pastes. • PCBs with both NiAu and Cu/OSP finishes were evaluated. • Board-level temperature cycle was run at –40/125° C for 1050 cycles. • Drop and vibration tests were run for the LLP package only.
