Has anyone used this product to bond a flex cable to PCB? I need to bond a flex cable on an LCD TV that has come loose. The pitch may be too fine for this product, but the other 3M products require precise heat and pressure (3M 5460R). It looks like it's worth a try since the TV is useless otherwise. Also, is there anywhere to get it in small quantities?
What is so special about it eg
3M 9705 Electrically Conductive Adhesive Transfer Tape, 12 in x 36 yd Price: $1054.32 Per RollI downloaded 3M pdf and skimmed through and its not "zebra strip" , what is the difference to glue backed aluminium foil ? I've never peered inside a non-CRT TV I might add.

Returning to that pdf I was reading about the shielding properties, not the anisotropy, so it is a sort of zebra strip.
If what is there is ok , just unstuck , can you not use a variant of this bodge that I use. Or is dirt on the tape a problem, presumably no great currents involved.
Bodge repair for failed conductive epoxy joints or where LCD zebra strips have lost contact because pcb has warped slightly or whatever. Push the section back with folded up strip of kitchen pan scourer, held in place against the casing / bracing and cable ties to pcb or something. The coarse open random mesh of plastic fibres is insulating and quite consistently compression springy.

Thank you for your suggestion, but I'm not sure what you mean. There are 96 traces on a cable that is 28mm wide, a very fine pitch. I think it is going to require a specialized product.

Me neither, I don't know what holds these LCD TV interconnects together , they sound like a horrendous bodge to me, as manufactured. Perhaps when mass-produced OLED comes in I could see the point of moving away from CRT.

Worse than your own horrendous bodges?
