Hi Sam
On one of the projects I worked on, we had a lockup problem ( CMOS issue ). It
would blow either the VCC or GND lead. We had a wire bonder in the lab. I'd
remove the cap from ceramic chips and bond on a new wire. It would work fine
until we sequence the power wrong and it would blow wire

Does this mean that, like me scratching a bit at the package to expose
enough nub of broken-off pin to get a blob of solder on to hold a new

of the package to expose the IC and then tack soldering the severed
wire back onto it?
