Zebra Strip Contact Reliability

Nelson · 2008-10-13T21:42:02+00:00

I have head several devices over the years with LCDs that were connected with Zebra strips and which subsequently developed display problems due to the Zebra strip developing poor contact with the PCB. Not surprising since the contact seems to rely only on pressure. Cleaning the surfaces, eg with alcohol, and reseating the strip helps for a while but the intermittent display always seems to return.Surely there must be some "connective glue" or other technique to repair these things more permanently although I have been unable to find anything with google.Does anyone have any experience or recommendations regarding this?-- Nelson

one guess is that the zebra strip is just fine but the pc contacts are corroding. Shine the pads up with some #0000 steel wool, protect them from corrosion with a dab of silicone grease, and reassemble. Worth a shot.

Why? If it doesnt work I will simply clean off the vaseline.

Good luck, if there is anything of the Zebra strip left to clean.
