What a nightmare I've had these past couple of days.
To start with I tried to install ICS/wingate, windows didn't want none of that, so it dicided to first get rid of my network (though it detected the card and all the protocols where set up), next it got rid of my internet connection (dial but IE looks elsewhere), and then finally decided it didn't like explorer so crashed that. Well now I've got no network card and the modem back, so I'll leave it at that.
Today I made a coldplate. No problem there, jigsawed and smooth as any thing.
However I took the heatsink off and noticed a little bit of green on the copper h/s, and it was in one corner of the peltier. Ripped that off, and there was a pool of it that had dissolve into the rubber. **** I said. Well the pins on the top hadn't tarnished so maybe it's not that bad. Just to make sure I ripped the whole insulation off. Heres what I found.
On the back of the slotket where the pins stick out, green gunk everywhere. Front is okay except one corner of CPU-green. Take the CPU out. green on the top of the pins. And the sticky label has clearly been wet. ****.
The rubber I used clearly was 100% impermeable. The insulation under the CPU wasn't closed foam (though it was sealed in it contained water vapour in it). Seal wasn't 100% around peltier.
Well the slockets going in the bin, the CPU still works though. Going to coat a new one with a) nail varnish b)enamel clear cote. Gona fill the gaps with epoxy resin. Bond the peltier coldplate to the foam insulation. Cover the whole lot with elaphant tape and coat that with epoxy/varnish/clearcote. I'm gonna try to seal the cpu to the slocket as well.
Anyway the morale of this is don't think that by coating everythink with 2mm of rubber it stops water vapour. And don't right long posts.
By the way cold, I'll get the photos developed tommorow, theres enough room for a thin cold plate in there as well as a peltier.
