Hi, thank you for the idea. I may try solder iron, but it much more slower since I have to solder spacers one by one. a stimpson press is used to press the spacer on the board and the edges of the spacers are rolled. Then we solder the edges to

Hi George, bad luck! That�s why we professionals get so much money for it. Those "thingies" are mainly capacitors or resistors. If a capacitor is missing you might with luck not even notice it. A resistor, that�s different, you will notice it, what

Hypothesis #1: We agree with Steve. You are probably seeing the nickel underplate. The gold was absorbed into the solder in portions of a second, so that you don't see it is not surprising. We're guessing that the gold was porous and allowed the n

It is possible that there is nickel contamination in the gold. Depending on your plating board vendors put nickel down first. The plating also could be to thin. Dave had a good suggestion in trying to solder the pad with a Iron that will tell a lot.
