Q.Hi, I would like to know if there is a faster way to strip silver from a stainless jig than the one I presently use. At the moment I use a mix of 19:1 sulfuric/Nitric @ room Temp. This works (slowly) but now we are finding that we have so much silver work to plate that ...
And plated on a printed circuit board immersion plating solution using ultrasonic waves plating bath and preparing a printed circuit board is provided at the solder mask, The method includes treating an immersion plating solution PCB I comprising the steps. During the plating, it was found to ...
Storage: As exposure to air tarnishes it, storing silver in airtight plastic bags with anti-tarnish strips is a great preventative measure. Just make sure you don’t store multiple jewelry pieces in the same bag: silver is a soft metal, so the individual pieces can scratch each other. Link...
Q.My quality manager has asked for a method or instrument to measure plating thickness. We have CRS parts finished with zinc+yellow chromate. Any suggestions? Doug Moyer - Radford, Virginia 1999 A.I would try the Kocour dropping test first. You drip acid onto the part, counting the drops ...
stand-off screws. This should result in you being able to see the holes of the stand-off screws through the holes on the motherboard. These holes will be shown on a diagram within the motherboard manual. They're also easily identifiable by the small silver dots around the outside of ...

Add your silver pieces to the crucible. Test the silver before using to ensure it is free of contaminants such as plating. Add casting grain according to the instructions. Continue to heat the crucible. Do not put the flame directly on the silver. Instead, move the flame around the silver...
By plating silver onto the outside of copper wire, you enhance its electrical and thermal conductivity, which are both beneficial for motors. However silver plated copper wires are way more expensive than normal copper wires, therefore it’s not very common in budget motors. ...
Silver plating of Tungsten carbide microspheres Q. We have a challenging problem. We need to coat tungsten carbide microspheres (approx. 635 micron diameter) with silver. We have been sputter coating but adhesion is not good. Currently wondering if an initial layer of electroless nickel my act ...
One way to strip silver plating off copper object is to use nitric acid, which when mixed with the right metal alloys, can give off nitrogen dioxide, which can become deadly. Therefore, only experienced chemists should try to remove plating from metal with the use of chemicals. If you must...
