Here's one picture:

Look at the left pad and the tarnish that you see there, does that look
like tarnished nickel?
This is after the board was washed. I have places all over the board
that looks like this.
I'll post a picture of what it looks like after I printed a solder
sample with paste and sent it through the reflow over

Hi all,
It's funny that the HASL topic has come up today, because we just ran a
board today that supposedly was lead-free HASL finished, and man it
looks like crap!
Question; does a PCB get nickel before it gets Lead-free HASL'ed?
