Photo was taken some minutes after pin 4 broke directly on chip. Please shoot me ...

If it was pin 5 you could use the pin 1 for +Vcc.... You are not a lucky guy

BTW, at least have you listen for "some minutes" ?

Not yet.
You can still salvage it by using the tab.

If it's any consolation, that's a very slick P2P job. One of the nicest looking I've seen, in fact.

I broke the pin1 V+. Then I got a sharp knife and cut through the (hard as a rock) epoxy to got a bit of the pin exposed. Cleaned it and soldered to a piece of wire. Not yet tested though.

Hi SmellOfPoo,

i broke some pins on smaller chips (opamps) and i drilled with these small high-speed machines and a small diamond cutterwheel. With this machines you can cut everythink - just to have take care not to cut too much ...

Years ago i reduced chipdimensions with this method to get electronic devices fitting into a pen (logic analyzer)...

Yesss ! After I found it´s impossible to solder something on the pad without frying the chip I took my Dremel and did it the same way. It´s very easy to do with a grinder and under the iron hard epoxy are at least 2 mm of pins.
