How are LCDs fastened to PCBs? They seem to be "glued" somehow to the circuit boards with some kind of conductive adhesive on the almost transparent edge connectors. Can anyone tell me how I can re-mount a display back onto a circuit board after it has come unstuck? And what kind of adhesive is used and where can it be obtained? Thanks, Harry - K5HML San Antonio, Texas

They often use something called 'zebra strip' - a sort of rubber with conductive stripes. The display is then clamped to the PCB. Leon

I recently, finally, found someone who makes and sells the stuff - http://www.zaxisconnector.com/ Never bought from them, no recommendation, just a link. Steve

Ok, but what about the displays where a thin plastic foil cable is somehow attached to the glass? So far i do not know any way to re-attach them once you ripped off a section by stupid accident. ST

Yes, but precise application would be required, to avoid shorts. It would be good to know what they actually use to put it together the first time. ST

At a guess it'll be some heat-sensitive slightly conductive (or with conductive particles?) glue. You could try a coolis (200oC?) soldering iron run along the back, as a last resort, but I fear you may be out of luck. Does it work ifyou press it in place? Hmm. http://snipurl.com/3m_lcd_tape That sort of stuff? Steve

I'd like to start a folder in Links for elastomer connectors and the directionally conductive tape. Suggestions on what to name the folder? Steve Greenfield

Another tradename for the elastomeric connectors is "Zebra Strip".

But they are for more than that, since I'm not limiting this to just the elastomer/zebra strip connectors. For now, I've called the folder "Connectors - flexible". Add links there. Steve Greenfield
