Hi, I was wondering if there is a preferred source of the .635mm ceramic substrate specified in the J STD 002 Test S and if there is what is the typical size folks are using (3" x 3"?). Thanks, Rich

Most ceramic you'll see comes from Coors or Kyocera. Size of your substrate will vary according to the stencil / component that you're using. 3" by 3" should be sufficient for most applications. If you get them too small, you could have handling is

Use a standard that everyone will recognize. If you say, "The solderability test was performed in accordance with ANSI/J-STD-002 'Solderabiility Tests for Component Leads, Terminations, Lugs, Terminals and Wires'” [ipc.org/TOC/J-STD-002C.pdf ], every

Sorry, scale division on that would be 0.05mm not 0.02mm. Magnification x24 or thereabouts. Also great for measuring all sort of things on pcbs, stencils etc to see if they come within spec.

I saw a post from last year that quoted Hadco. For a .062" thick PWB, the remaining material was .012" +/- .002". This is close to what we have been using, but some PwB vendors are now asking for .020" +/-.005". This seems too thick for smooth bre
