Repairing touch-pad membrane's

[SJM]

Hi all,

I've got some touchpad membranes I need to clean up, does anyone have any
recommendations on how this is done, do I just seperate the layers and give
them a clean with isopropyl???.

Also, I'm looking into a spray-on/spray-off or dipping (perhaps ultra-sonic
bath) method to remove grease and cockroach droppings from PCB's. Has
anyone got any tips on this.

Thanks, J

found flux cleaner works quite well for grease on pcbs.
just be careful of plastic bits.

don't buy from jaycar or dicksmith, way to
expensive.

Place near homebush(can't remeber the name)
can buy 3 litres for the same price dicks smiths charge for a spray can of it.

Or there is the guy based up in
Gosford who comes around in his van, sells soldering and test equipment and accessories.
Pretty good service.

the best ever electronics cleaner I saw used trichloroethyline (dri-cleaning
fluid) in a converted refigerator. It has a cold ring around the top and a
hot ring around the bottom so that the solvent recondensed at the top and
dropped back down to the hot fluid in which the parts are dunked.
