Ok...so I'm working on a project....that I would like to keep my code under wraps.....(sorry this is not the correct place...but you guys are so helpful)....
What consideration(s) should I take into account for potting my project after it is finished?
I know that any high amperage voltage regulators need some cooling...what else?
Also what is the best potting for such a project?
Thanks,
James L

I thought there were more important factors for potting electronics, like thermal transfer and such.
Although I have never potted a board before.

Sid,
To ask a stupid question, what exactly is the difference between "military" and "industrial"? I gather that the military stuff can handle temperature better, but other than that...???

Military grade components usually come with a certificate, certifying they have been through a burn in and test process and stating exactly which military standard tests they have been subjected to. You can also tell by the price! It is hard to get to Mars to fix an IC on rover!

Yea.....sorry you didn't see....I could omit the regs(from the potting)....if possible to isolate....I did comment earlier in the tread that a daughter board may be in order.
There are other reasons for the potting....other than code. I must ensure people do not modify the circuit and also from vibration. I know this won't help the internals of the chips, but will help with the components themselves.
But Paul...thanks for the suggestions.
Tracy.....thanks for the name of a system specifically for potting....that was what I was looking for. Although I could have searched the web, I find personal experience with a product goes a long way.

My question is, can anyone recommend an inexpensive generic rhyonite or plastic
box manufacturer for small quantities ? My microC-gizmo goes inside this box, the box gets
filled/covered with compound.
Size of the box LxWxH in inches is about 4x2x1.
There has to be a place that would sell one for some like 1-2 $ even in small quantities.
I can not believe how expensive a small piece of plastic can be, based on what I found so far.
Thanks
(sorry about the off-topic)
