Hi guys,

I'm examining our current site policy on degolding of SM components prior to
placement, e.g. fine pitch QFP's etc. I'm pretty well versed on all the
metallurgical aspects of gold in solder joints however I'd be interested in
what is being done in the rest of the industry. Are you guys degolding ? If
not, have you any specific problems which a gold finish has caused, e.g.
wetting, joint failure. My application is high reliability military
electronics.

Thanks in advance

Bryan Kerr
