Vijay, Sounds like you're not spending enough time at liquidous plus 20*C. And you need to stay there for 5 to 10 seconds. I know, I know. We have used bucketsful of WS609 over the years. See, as you say, the melting point of your solder alloy

Back in the 50's, 60's and 70's gold plated boards were all the rage for high reliability. test equipment, milspec etc. Nowadays only edge connectors are gold plated. Immersion plated gold is also used but it doesn't last the distance like gold plate

What is the use of gold plated boards?

Has anyone had any experience with using this alternative plating process? Some board houses are pushing toward this plating. Is there any long term data on this process? Any problems experienced with smt and thru-hole? I've heard tin whiskers to be

When discussing this with the customer he said that his vendor recommended a hard gold plating finish on the board due to the BGA. I said "hard gold"??? And he said yes, hard gold. Turns out the boards were plated with hard gold, not ENIG. Thank

Points to consider are: * Gold plating too thick [SB LT 8 uinches]. [Obviously, we're talking about actual plating thickness, not the specification.] * Reflow recipe improper [SB 220*C 5-10 sec]. A recipe that works fine for HASL needs to be hotter

> What is the use of gold plated boards? <BR> <BR> With the increasing integration of IC, the more IC the more dense. The vertical tin spray process is difficult to flatten the pads, which brings difficulty to the SMT mounting, and

What does a section of the through hole look like? Is you fab using a dull drill and plating over the fibers? Good luck

I have a component manufacturer that is using Sn/Ag/Cu plating on chip caps and resistors. Does anyone have any information on compatability with Sn/Pb paste. Are any changes in profile required? Is the reliability of the solder joint at risk? Tony
