| I have used conductive adhesives for some time now on thickfilm. Does anyone know of a really good conductive adhesive to attach flip chips to flex circuits? I would like to stencil print the adhesive to the substrate and then place the flips chi

I was wondering if anyone has done a study on thermo couple attachment with light cure adhesive.I have read all the papers and articles about aluminum tape, Kapton, and high temp solder.I have yet to hear anything regarding the accuracy of light cure

Hi Joshua, No, the adhesive lasts 2 or 3 runs. The adhesive is put on manually as is the kapton. It's a big panel for a flex - nearly 300 x 210, so the operator loading the boards onto the pallet and fixing them (then into a buffer) stays well ahe

Hi John, We use Spray mount adhesive on durastone pallets, then kapton tape on the egdes. We have produced upto 25K flexi PCB's a day with this method. The trick is to get just the right amount on the pallet, to maintain tackiness. Cheers, Rob.

Hi Rob, So do you have to constantly remove the old adhesive and spray on new ones? Is that an automated process? Also for the kapton tape removal and application, is that automated as well?

second the kapton tape. Another tape we use alot of is powder coat tape (a tan color) because it has excellent heat resistance and a good adhesive that does not leave residue.

My guess would be that the adhesive used on the dots contains silicone. We use 1B73 which is also acrylic and it hates silicone. We use silicone RTV to permanently mask around some connectors and unless its fully cured before coating it will cause l
