Abstract :
The solderability of SnAgCu (SAC305) and SnCuNi (SCN) alloys for DIP components on thick PCB (2.3 mm) with OSP and LF-HASL surface finishes were studied. Force rework was also applied after DIP process by using SCN and SAC305 solder alloys. In addition, the SCN solder properties, including copper dissolution, mixed alloys, solder joint corrosion, and corrosion property to soldering tank were tested.
