Hello all!
in Hokes book, he says to prep by acid bath like nitric or HCl. I was wondering if anyone ever has done Sulferic Acid. Ive seen a video of a lot of copper removed using a sulferic bath with sodium nitrate.
Discovery:
1. Ive been collecting a lot of my gold and have discovered that ive been using too much SMB causing my yield to be a brownish grey color. Is this true? Can this turn your yield grey?
2. So ive discovered the powers of gold pins using vinegar 75%, a little salt, and h2o2 12%. I got ALL gold foils removed after 30 minutes. Its incredible (picture attached).
3.ive been doing like 80-100 grams of stuff but my yields really REALLY small. Im thinking around right now aftsr processing: a total of 400-500g of material (gold pins, i attempted transistors but their copper plates are hard for me).
Do IC chips have good yield?
