Hi All,

I have been forced out from lurking in the shadows and listening to all the great knowledge.  

I have been tasked with providing procurement information for the supplies/materials necessary to test some solder paste attributes at all of our sites.  

Doing fine with stencils and glass microscope slides.  Not finding anything on the copper test coupon for wetting test.

Does anyone know of a source for the coupons ready made?  A plus would be ready made and OSP coated.

If ready made coupons are not available and you are testing solder paste for wetting, what do you use?
