Interesting......... they got a patent on insulating solid core conductor wire????????? Someone should go patent the butt to make sure they never sit down again at the patents office.

But, Joyce, who is at ECTC right now, may be able to shed some light on this from her time at Microbonds, where their main patent deals with putting a coating on gold bond wires that allows them to touch without shorting out. On a shiny surface like that you MIGHT be able to determine presence/absence by FTIR, but maybe not because of the thin nature of the film. Certainly we have not been able to confirm the presence of material in water spots on gold surfaces. Two techniques that come to mine to try and Auger and/or XPS, but I am not even a novice in either technique. Both are very expensive.

Polishes have at least two purposes. Grind the metal to get a certain level of brightness (we polish to Ra 30 nanometers). And leave a thin coating that protects the metal. Now, in our case, what is left is so thin, that you can't observe the 'coating'. Presumably because it's an organic compound of some sort, and also because it's transparent for our eye's wavelength. Now comes the question: has anyone out there ever investigated such a 'wax' and determined the thickness, and if so, what kind of equipment was used? That's why I more or less directed the q to Bev...
