'Afternoon, All,

Today I need your help to find a good guide on how to select solder
mask/resist materials and how to determine what thickness should be
specified for particular applications. Immediately I need to know
recommendations for 0.063" thick, 10 layer FR4 HASL finished VME
conduction-cooled boards of 15 mil track spacing for military application.
Boards will be Convection Reflow Soldered with Kester 63/37 solder and 331
flux. Anything else you need to know?

I'm from a manufacturing background and have never needed to know this
level of detail before. However, I am now involved with helping a bunch of
design engineers who have even less idea than I do about this sort of thing
than I have. I have had a go at the Web trying various terms and key words,
but get absolutely nothing useful back at all, so I'm hoping our TechNet
Goldmine/Delphi Oracle can succeed where the WWW has failed me.

TIA,

Pete Duncan
