We use lead HASL because gold plating can hide defects in the nickel plating that can create poor solder joints because solder won't stick to corroded nickel. The gold also can embrittle solder joints which is bad for applications where lots of vibration is a concern.
- swamp40 4y agoI didn't think you could use lead for anything but military stuff? We have RoHS requirements everywhere. The gold is so thin I would think you could see a nickel problem, but IDK. Most of our problems come from lead-free solder, it is very brittle. I didn't know the gold could make it worse.
