Hello,
I have a TI92 calculator which starting missing vertical lines. I tried to use ACF with one of these Tbar with silicon but not much progress.
The ribbon has yellow "paint"/protective layer on top of the conductive layer pads. When pressed with the T-BAR on top of the assembled ACF strip it conducts (tested with aluminium foil and multimeter/ohmmeter in the other end) but after removing heat/pressure it stops conducting. What is the process? First ACF on the rybon or the parts? Do I need to clean the yellow paint? I assume it produces some hight having the paint. I first tried to apply ACF on the parts so not sure if is the right process, or if ACF goes on the rybbon first.
Thanks for any help,
BR,
Jorge
