DVD/CD Signal Processor missing legs
DVD/CD Signal Processor missing legs –
Due to a rather extreme accident I managed to damage 5 of the legs on the chip to the point where they had to be removed.
Is there anyway to replace these things?
u have a pic from it ,would be helpful
Can't get a picture of it. Legs have been pulled clean off. Nothing left but the contacts on the board and chip.
you need to cut away at the chip with a dremmel to expose the proken ends of the legs and attach those to the traces with wire.
The wires came off clean, the contacts on the chip and board can be seen and look fine.
The problem is that these legs are so thin. I tried seeing if normal copper wires could connect them, but 30 gauge wire is too thick and I don't have anything precise enough to work with it once its cut and sanded to size.
use enamel wire (from a primary coil of a small transformer) to connect what is left from the chip to the board.
Did the board's pads remain intact after the accident??
From what I can see the board's pads are fine. The thing is, once I get a wire sized correctly to connect them, I have no way of actually positioning and attaching it. Its just too small.
in case u r using enamel wire, solder a large >5cm piece on the pad and then estimate the spot that it will touch the IC's leg, then aply solder on that spot to burn the vernish and then touch it on the IC's leg and solder it. Finally cut the excessive lenght of the wire!
This is the signal processor on a V7. Each leg/contact is under a millimeter in size and I don't even want to estimate the almost nonexistent space between each one. The drive won't read unless it not only has all of them connected, but also none of them bridged.
I have to use a microscope of some sort to even see the spaces inbetween each set of contacts.
