Amiga 500 Keyboard membrane fix
Hi all,
I had an a500 keyboard that wasnt working, the Return, delete and a couple others weren't working so i took a look and i found that some of the traces had disintegrated for whatever reason by the "Return" key. so after thinking on how to fix it i tried some thin wire and a nickel liquid pen. I scraped the carbon pads a little to roughen them up, laid some wire, taped it in position and then applied the nickel. Let is sit for a few hours and am happy to say it is ALIVE!! http://www.kipper2k.com/a500/a500kbfix.jpg here is what i used... https://www.digikey.com/products/en?keywords=841AR-p |

Good information. I also have some keyboards to repair.

I had an Acorn A3000 keyboard membrane which battery leakage had damaged the traces on the flexi at the connector. The connector was completely ruined.
After reading the OP I tried a repair with a nickle pen (I have the MG chemicals brand). First I cleaned off all the flaking traces from the flexi with IPA & cotton buds. I then repaired the tracks which push into the connector with the nickle pen. I did it under a microscope which made it easier to clean/paint. Leave it a few hours to cure and it worked perfectly. The nickle flakes off a bit if you remove the flexi from the connector but that can be touched up. Seems like a good way to repair rare keyboards. So it is possible to repair flexi-edge connections with a nickle pen! Thanks for the inspiration kipper2k. |
