I have read that it is possible to use JB-weld and packing tape to reinforce the FFC's and have a few questions. Since I have yet to strip my monitor, I have "borrowed" a pic of an FFC from another post .

1) Am I correct in assuming that it is the blue area where the JB-weld needs to be applied?

2) Does the JB-Weld go on the LCD end of the FFC as well?

3) Does the packing tape go on before or after the JB-Weld?

Thanks for any clarification.

Sonic? since JBWeld is basically pulverized steel and epoxy resins, is there any chance of it being electrically conductive?

Anyone?....Bueller....Bueller...?

Im thinking I would rather go the hotglue route....

Well better to be wrong and find out....

SonicWonder2000:
I got curious about it since epoxy resins should not cunduct electricity and went to the jb weld site. This is what they had to say:

When cured Adhesiveweld is completely resistant to water, oil, petrol,diesel and most aggressive chemicals such as battery acid. It is also non corrosive and non conductive. This means you can use it as a circuit-breakeror where corrosive chemicals are present or in a hard climatic environment.

I love this stuff....

Yeah, I guess the steel particles never create a continuous medium within the resin so they don't conduct! It is very inductive from what I understand, though. So, is the blue area where you are supposed to apply it??

I say we dip the entire thing! No I guess you should look and see when they move where the greatest tension from the flex shows. Thats probably the spot you want to hit. I think I read that post to, but I was thinking that you could stiffen the flat ribbons with the bendy plastic from a coffee can lid. Nice and flexible and secure the FCC to it...

I actually considered painting the entire cable with JB-Weld. That would be the ultimate reinforcement methinks ...

JB weld doesn't conduct electricity although it is highly inductive. I prefer silicone in the small tubes with a pinhole at the tip. As far as placement, I'd put it on each side of the mylar at both connections shown by the yellow spots. Be careful how much heat you apply as the Anisotropic Conductive Film could lose it's bond.

Thank you for the clarification . Stripped the LCD last night - JB-welded seams. Powers up good - thank GOD!! One worry out of the way ...

Kind of. :angry: I seem to have a small scratch on the LCD surface. At first I thought it might be lint (it still might be) but blowing on the surface didn't move it. Hoping it won't show on the projction . The only thing I can think of is that the diffuser sheet that I used to "protect" the LCD had some debris on it and this caused the scratch. Man these things are brittle - Brain surgery might be marginally easier
