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*

1. To protect the nickel and copper under gold plating from oxidization before soldering. Gold plating can extend the PCB self-life and improve the solderability for 2nd re-flow. 2. Provide a good bonding strength. For Chip on Board process that Gol

Matt: What thickness of hard gold was applied to your customer's boards?

Not reflowing completely. Slower = hotter. Try a slower conveyor speed.
