Here is an opinion p.1/p.2 is %@##& stupid. Keeping files in different folders with the same name can lead to a mess if one person one time makes a one mistake. Could I call this company and order a p1? (rhetorical) Russ

You should see a coarse silverish / grayish coat on the termination that indicates that it soldered. We have to opinion [don't know] about the strength of solder connection versus the strength of component terminations.

OK. Point taken, lets keep this simple then, how about just the issue of under cured solder resist? Any body else encountered such issues. Just feedback, 'cause its something that just seems to have been highlighted to me. Thanks.

Hi Sam, I am going to guess that a problem is being caused by processing to effect the inside of the LED package. Send some failed LEDs back to the manufacturer to do a failure analysis. Also ask the manufacturer for info on their SMT processing q

Sam: If your gold overcoat was pourous, the nickel undercoat would corrode prior to your attempting to solder and you would not be able to solder without an aggressive flux. Since you see solder flow and wetting, it indicates the gold did an adequat
