Coating a Motherboard In Thermal Resin? 272
Bat Country writes "I've had an idea in the back of my head for some time (and I'm surely not the only one) that it would be a worthwhile project to coat a motherboard in thermally conductive electrically insulating resin — complete with all of its various components — for the purpose of immersion, shock resistance, whatever. I'm curious to find out if anyone's undertaken a similar project or if it's known to be a shockingly bad idea (due to shrinkage during the curing process) already. Thoughts?" If you've done anything similar (even an experiment that failed), how did you go about it?

You: Hello Doctor! 5 gallons of your finest horse laxative please!
Vet: Oh, got a sick horse then? Are you it needs a laxative?
You: No, it's for me, eh I mean, it's for my computer!
Vet: Ah, the computer! I see. Say no more. *wink wink*
Try Mineral Oil (Score:5, Funny)
People have been running PC electronics submerged in mineral oil for decades.
Advantages:
1. Not too hard to do
2. If push comes to shove, you can can probably burn the PC in your fireplace or other suitable container to keep warm. Or just because you are pissed at it.
Problems:
1. It's messy.
2. The oil tends to creep up any wires to the outside world (capillary action?) and eventually show up at the other end.
3. I'm not sure if non-gas tight connectors are used in modern PCs, but if they are, they may be a problem.
4. It's messy.
Did I mention that it is messy?

Really. It almost sounds like something out of the show.

Vet related too (I do the IT for a group of clinics) but not that relevant:
Customer: "Are gherkin (pickle) slices bad for dogs?"
Receptionist: "I'm not sure - I'll ask the vet...well, the vet says in small quantities they should not be harmful...has your dog swallowed one?"
Customer: "Oh, no, we just wondered whether we should remove it when we buy our dog a burger at the drive-thru"

Just try it. (Score:3, Funny)
It's a few hundred dollars, at most, to test this theory. Go try it. I promise the results will be more useful and interesting than anything you'll get back from Slashdot (e.g. theories on mineral oil suspension, stories on potting mainframes in the 70s, etc.).

Sticks and Glue. . . (Score:3, Funny)
Hm. I remember doing that exercise as well. --I think the scoring formula needed to be adjusted, because my solid bundle of sticks soaked in glue creating basically a polymer enhanced log could take all the weight the testing apparatus was able to provide, plus that of the teacher and two students standing in a rope looped over my 'bridge'. It never broke, thus my ham-fisted design won the contest despite the ridiculous number of pieces used to make it.
It was also generally agreed that I was an ass and that the real winner was the team which had came up with one of those conventional erector-set type designs.
The point which led me to this idea was that I'd noticed in the scoring formula there was no limit on the amount of glue we were allowed to use. I'd considered making a solid log of glue with a single strut buried inside it, but the drying times wouldn't have allowed me to finish the project before testing day. I think one of my purposes in going through the school system was to spend as much energy as possible challenging the silliness of conventional thinking, though at the time I was giggling too much to take notice.
