You have provided very little information. Two similar possibilites come to mind: poor pad solderability protection and old boards. POOR SOLDERABILITY PROTECTION: Maybe the nickel plating under the gold is oxidized, contaminated, or otherwise very

In regards to PCB assembly, what defects can be attributed to inadequate board support fixtures or systems?

Hi everyone: Our company is trying out immersion white tin for fine pitch assembly with what I would call mixed results. Reflow solder looks very good, but wave solder looks somewhat grainy (this may not be a problem in actuality). We had dewettin

What is your board finish it sounds like an osp. That type of thing is common with osp finishes.

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

Why use labels? They are expensive, fall off, get mangled, etc. If you directly mark the boards, you'll probably save money, enhance traceability, etc. One major contract manufacturer projects payback at 7 months just eliminating label cost and goin
