what do you use to encapsulate electronic projects?

I'm not sure what potting compound means? Are you speaking of a box, or enclosure?

You can buy boxes and enclosures to put your circuits in. You can buy these from Radio Shack, Digikey, Circuit Specialists etc.

Or you can make a little wood box, or bend tin or 16 gauge steel to make a box.

The possibilities are litterally endless. You can use old card boxes, etc.
 
encapsulation

:D hi,

are you referring to try to hide the circuit? if so i use epoxy provided that the circuit does not have to dissipate heat. :D
 
if you are talking about boxes heres a cheap alternative.
and it fitts "AA"'s perfectly.

Thanks for the replys, but i am refeering to an epoxy encapsulant. I want to hide, and protect my project from heat and cold.
 
Need More info on the use!

Can you give us a few more details on the circuit you are trying to protect? Does it need to dissipate any heat from transformers on transistors or capacitors or any other parts?

Also are there any I/O lines (wires) going in or out of the circuit board. And most importantly, how big is the board?

There are reasonably cheap 'off-the-shelf' type kits you can buy from local electronics shops, but they tend to be low quality type potting compounds. If you are trying to protect this circuit from heat and cold, you may have problems with expansion and shrinkage with potting compound surrounding the board, especially if it is a large board.

Most companies only use potting compounds to protect the circuit from tampering (High secrurity risk circuits) or from the cold, to protect from heat the cooling of the board tends to be done with airflow.

You will also need to be certain the components you are using will be able to cope with the low (& High) temperatures that you want this to operate in.

If you give me some more info on what it is youwant to do eactly, I can point you in a better direction!

Hope this helps,

Paul
 
my circuit isn't using too much power, and I haven't noticed any heat from the voltage regulator at all on my breadboard. using a 7805 to take 12v from a car battery and dropping it to 5v.

yes on the I/O lines. i am thinking that it might be about 2"x1.5"x1" maybe a little bit bigger. a lid will not be used either, as i will have the i/o lines come right out of the compound. I wan't to protect the circuit visually, and from heat and cold, since it will be mounted under the hood of a car.

thanks for any help.
