flexible pcb repair

Hi, I am in a bit of a fiddle as I have a projector worth over $2500 and the flexible pcb connecting one of the lcd panels to the main board has broken (the gold fingers have been cut off - of course this is due to me opening the thing up in the first place so it's my stupidity) - The flexible PCB is still long enough to reach the connector but it needs gold fingers on it .. I know that technically it is possible to repair this but really specialised equipment is necessary. Is there a service anywhere in Perth where I can pay someone to fix this PCB!? .. I have no alternative as apparently the lcd panels cannot be replaced individually and to fix the unit will cost in excess of $2700 - not worth it! I hate to see a perfectly good 6month old projector goto waste because of one cable breakage..



Thanks for any advice,



Sean

Sun Industries in Osborne Park make flexible PCBs, maybe they could suggest a fix or repair it for you.

The covering on the tracks can be removed if they are in the right place to fit in the connector. It's a separate laminated layer that you may be able to remove with care and a scalpel.

Alternatively contact the service agent for the brand and get a new board fitted.

Here's another method using 3M Scotch 9703 conductive tape:

"Tape 9703 is an isotropic, electrically conductive, pressure sensitive adhesive (PSA) transfer tape. It is a permanently tacky system consisting of a PSA matrix with aligned conductive particles. These particles allow electrical conduction through the adhesive thickness ("Z-axis"), but not in the plane of the tape."
