Doug: While your points are well taken, we've never heard of "bright tin" immersion plating. Electroplating is our bet.

....how does the part perform in a wetting test. Is it solderable on a bench or dip-plating in a pot? If you add flux and heat can you fix your problem assemblies? If yes, plating finish or substrate is not your problem. What flux are you using?

Matt: Yes, if the gold was really thick, it could appear like your pictures. In measuring gold plating thickness, we'd want to use xray fluorescence [XRF]. For alternatives, look here: http://www.pfonline.com/articles/pfd0027.html

Very interesting tread, many thanks to all. Matt please, now what does it mean for you? Will your custmer accept dull solder joints or will the plating be changed ? (ie. HASL, ENIG, etc) Tnks and regards GS*

Agree with Dan - we have had non-plated IC's that are a bit corroded come in and seen similar problems. Could it be that the tinning/plating process missed a corner somehow???

Try home-plated the stencil apertures, and make "V" shape home-plated outside edges of two pads instead of between two pads.

Nomorely the V-shape home-plated apertures look like two opening mouth facing each other. But this time just opposite way. And make 30% home-plated. Hope you can understand.

Hi Does anyone know where I can find information with regards to what is allowable when it comes to scratches and the depth of scratches on gold plated items Thanks Adam.

Hello all! Our test adapter have not a plate, which close test probes. We want to do a plate with through holes for test probes and holes for guiding and centring pins. We want to order a making this one. Adapter is MTS180. Thanks.

BeCu is not solderable without plating Cu, Sn, Ag, Ni etc. The solder joint will only be as strong as the bond strength of the solderable plating to the BeCu Pat
