Repairing a vintage rubber dome keyboard from HP
« on: Thu, 01 August 2013, 17:32:47 »
Hi,

this is maybe not the best place to ask for it but I know no RD forum ;-)

I have an old keyboard from a HP Vectra PC wich has some problems with keys not responding. The keyboard is not like modern rubber dome keyboards build with 2 films with contacts. It has only one and the rubber matt has some electrical material for bridging the contacts. The problem is that some contacts on the film have been rubbed off over time. Is there a way to restore them?

I thought about some silver conductive paint but I don't know if this would work and just trying could damage the keyboard beyond repair if its not working...

I just like that old kyboard and another one is extremely hard to get. (If someone has one that is working, I'm interested)

What do you have to lose?

I have never tried this, but that is the only solution that comes to mind.

What I have to lose? A second try with some more promising material ;-)

Thats why I'm asking here before doing it. Maybe someone has already done something similar.

Maybe one of those circuit writers/trace repair pens might work ? I've seen those around for $8-$10.

Hey, that looks good. Didn't know such pens exist. Should be similar to the conductive paint but easier to apply (which was one of my main concerns)
