Steve, Doesn't look like much of a coat of solder. HASL strips off a lot but that just looks plated to me. Chuck Charles W.

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 Steve -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Steve Gregory Sent: Tuesday, October 1, 2013 4:16 PM To: [log in to unmask] Subject: Re: [TN] HASL question Ahhhh....it's what I figured.

Question; does a PCB get nickel before it gets Lead-free HASL'ed? Steve -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Vladimir Igoshev.
