Hello Dears,
Once again, I need your kind help:
I was trying to process around 0.25k of gold plated pins but with tin solder tips.
So, I started by soaking these pins in HCL and left it over 2 nights. While checking the patch i noticed that the tin solder tips were gone but also a black/grey coat is covering so many pins.
I think this black/grey coat is tin plated out the gold pins.
My question now, is how to remove this tin black/grey coat out out pins so they will be ready for processing ?
