We've just completed an experiment for one of our customers using lead-free HASL.

From a manufacturing standpoint, everything seemed to have run fine. Solder profiling seemed to be unaffected, pick and place was unaffected, and the end result looked quite acceptable.

There were no fine pitch devices on this board, and nothing smaller than an 0805. I had no need for the coplanarity advantages of immersion gold or silver.

cheers ..rob
