Profiling for Pb-free HASL | 9 May, 2019

I'm curious about what you guys do for Pb-free HASL profiling.

We seldom see this finish (only on consigned boards or if they specify it directly, which is very rare) so we don't have a lot of experience.

Certainly we get better results with higher peak temps but I don't like to increase my ramp temps very much for fear I'll be out of flux by the time I need it.

Does anyone use a different paste just for this finish?
