If the HASL is so thin that you only have an intermetallic layer left.   How efficient will the solder joint connection be.

Sure it wasn't immersion tin? You can't tell the difference by color, but immersion tin is extremely flat. HASL usually is not.

I have seen high quality horizontal hot air level which was so flat (by eye) I didn't realize it was HASL until told.
I've never seen vertical HASL that flat.
