Dave,
We see this on fairly frequent basis. Usually needed if a MIL-type
requirement of ".0003" as deposited" is specified. Also, if other
selective metalization, such as soft gold, is required in other areas
of part, HASL becomes a hassle (sorry, I had to), with masking and
such.

Subject: [TN] FAB: Selective Solder Stripping

I was approached today by a request as to whether we could supply selective
solder strip boards. These boards were reflowed selective solder with hard
gold plated fingers. I hadn't heard of this for a number of years since the
advent of HASL and I was wondering whether there is still widespread use of
this process. Can any users or manufacturers of selective strip confirm its
use in their operations?
Just curious....
