Qdeathstar:
Hi,I have a esp8266 that i want to partially pot into a milled out aluminum bar, mainly to hold it in place. I could just use some silicon caulk, but, i want it to be more sturdy than that... so is there something i can buy locally that will work as a potting compound w.o damaging the board?
I know i can get potting compound, but i'm trying to wrap this project up this weekend. Will just two part epoxy work ok for electronics? I won't be potting the antenna portion.
Unless you REALLY NEED your module to be potted (for example, to survive in harsh weather conditions and/or lots of vibration), I heartily suggest NOT potting it.
You can get one of those nice plastic cases with a groove and gasket built in and seal your circuit inside while still being able to remove it for repair or reprogramming.
If you DO intend to pot the circuit, don't just use any old caulk or epoxy. You need material specifically made for potting (i.e. electrically insulating, does not release conductive ions while curing, not corrosive to a PC board, flexible enough to allow thermal expansion, etc...). Also, some materials release a lot of heat while curing (many epoxies do this) and the heat could kill your board.
I suggest researching circuit potting compounds (GE makes many different kinds of silicone products... soft, firm, clear, opaque, etc...)
Good luck.
