If it was pin 5 you could use the pin 1 for +Vcc.... You are not a lucky guy :p
BTW, at least have you listen for "some minutes" ? |

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

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

Thats it !!! Are there any drawbacks in doing that ? |

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 itīs impossible to solder something on the pad without frying the chip I took my Dremel and did it the same way. Itīs very easy to do with a grinder and under the iron hard epoxy are at least 2 mm of pins. |

I'm, a fan of P2P but believe that you should support components connected to the pins of the chip to prevent undue strain on those pins!
Hot melt glue is easy to use, does the job, and allows components to be changed later without too much hassle. It's better than dealing with broken pins! :att'n: |
