| Anisotropic Conductive Film to repair a TI92 ribbon cable? |
| (1/1) |
| jorgemef:
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 |

--- Quote ---but after removing heat/pressure it stops conducting --- End quote --- That sounds like either you're not getting it hot enough or the time spent under pressure is not long enough. What ACF are you using? |
