Broken leg on webcam CCD
« on: 12:27:55, 27 July, 2008 »
Whilst trying to fix another problem with my modified webcam, I've managed to snap one of the legs off my icx414 ccd :'(

There's a teeny bit of metal visible, but have had no luck soldering to. I'm sure someone must have had a similar situation (or at least with a microchip or similar) and was wondering what the best method of recovery is, trying to solder on somehow, or digging into the chip? (or something else..)

Any help is very much appreciated.

Dave,

I did a similar thing to my Vesta 675 only I had no metal visible.
What I did was scrape away some of the body of the chip so just a little of the leg within the chip was visible.  I then hot glued the wire of top of the body of the chip.  Next I soldered a tack of solder on the wire to the part of the leg I had scraped away.   The camera worked for years.

Thanks Clive, I thought that'd be my best bet.

The CCD casing was so hard I wasn't getting anywhere scraping away, so I used a small drill with a 0.5mm bit - and about half an hour later had a small amount of metal exposed. After a few attempts I got a small wire to solder onto it, and will now cover everything in glue :happy:

I've just tested it and all is dandy :D I've been having so many problems making this camera :hurt: but looks like it'll be finished soon. I just need to seat and secure the CCD now (when the glue is thoroughly set!).
Will post more info and pics in the project board if it's ever finished.

The wire came off again when I glued the CCD in place  >:( but after drilling through the epoxy, I soldered it on and glued it on place for the last time. Everything's firmly secured now.

I've stuck a few pics here:
