A most excellent response, Richard!!! 3 to 30x spot for this gold wire!! As I recall, it takes drilled diamonds to do the required extruding as well.
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...
Teach me something here, Richard...
1) When the wire thread broke or got tangled when the machine burped or power sagged or the thermal bonding fuser burned out, what were you all instructed to do with the scraps?
2) How tough was it to thread one of those things with a new dia wire when job specs changed?
3) Were there ever any applications where, due to cost, that platinum or palladium fused wire was substitued? That would have required a higher temperature for the thermal fusing process, yes? No?
4) If yes, when and for what applications?
5) How many "miles" were on one of those spools of gold wire thread?
6) How heavily guarded were the employees in that application "room"/cubby?
Fascinating stuff, Richard.
Thanks again!
