Sure, just as the "mark-up" over spot for jewelry includes the jewelers labor, the high labor, precision, and technology costs are included in the cost of the finely extruded tiny gold wire. Purity & precision of dia & or alloy are the key factor in the bonding wire while it is fashion in the jewelers trade. Remember a couple of years ago when I posted the news story about gold bonding wire being stolen from INTC? If I remember correctly & "the rules" still hold true, the cost of the bonding wire can run anywhere from 3-30X spot depending on point time within semi-conductor cycle, lead time, order size, and other factors... . Here's a link which speaks a bit more about(and sells) 99.999 pure bonding wire:tising.es Here's a better one that offers options of alloy & speaks to dia.kns.com click "Fusing Current vs.Wire Diameter" & "Electrical Resistance vs. Wire Diameter" for interesting pop-up windows You'll notice even the "least pure" gold alloy is still greater than 99% gold: kns.com while the "most pure" far surpass the "least pure" with non-gold elements running at <100 ppm.kns.com See the (magnified)pretty pictures of the bonds of the gold wire at above. Also interesting are the data sheets on all their products (in PDF)kns.com also seekns.com Ball bonding is a greatly fun job when everything is running just right & you are using(quality) gold wire & the other components that the wire runs between are also good quality. It is a thing of beauty. Sorry, should also mention that the best bonding wire when I chased (& or "used") bonding wire were *and I suspect still are) Swiss made and if the Swiss Fr. is strong against your currency the day you make the deal or take delivery - you might be screwed.
