Wire bonding machines have been transitioning from gold to copper wire, so you should be able to find some useful bits for your machine from there. I don't think you want to solder, I'd probably be inclined towards the wedge bond or "second bond", which is how a typical wire-bond is attached on the lead-frame side. Basically, the fine wire is simply crushed against the leadframe, welding it into place. -- Charles Steinkuehler char...@steinkuehler.net
