Potting for Automotive electronics
« on: September 12, 2021, 01:12:04 am »
Can anyone advise me what type of potting is used for this type of Automotive electronics.

It has a sort of rubbery feel to it.
Even better if it has good thermal conductivity.
Thanks in advance.

The rubbery stuff is typically a silicone based compound. I don't have a specific product for you but I'm sure there are a whole range of them.

Look for Sylgard from Dow.  Don't expect great thermal conductivity, although there are epoxies that are better at that.
A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit 7.5 digit DMM is good enough for most people.

I think it was in a Big Clive's video when he opens some of this potted stuff and found potting is relatively thin and inside is filled with sand-like material
But it was probably a cost measure as those pittings are on an expensive side

Yeah that's definitely not the correct way to do it, potting should be used on its own, but yeah it's relatively expensive so that would be the reason a sketchy company might use sand as a filler.
