potting contacts
(1/4) > >>
Simon:
I am looking at a few things that do not need to be waterproof but it would be a nice option. But my design relies on boards that are plugged together. I think this is a bad idea for potting, am I right? is it the sort of thing that a soft potting will work with?
Gyro:
I agree, it feels like a bad idea. I don't know for sure though.

With soft compound there might be a chance of compound working its way under the contacts if they shuffle due to vibration. With more rigid compound, it might 'set' the contact spring shapes. There's also the possibility that anything (moisture, uncured constituents?) released from the compound might contaminate the contact surfaces without anywhere to escape to.

you could extend some wires from the modules rather then direct fit

I was thinking soft compound would allow spring contacts to keep sringy but hard could be a problem with varying temperatures.

I could have one board slotted and insert the other card into it and solder but with a double sided card that now puts a hole right though the board I can't run traces under the joint, I'd have to take the tracks around the side. Which is a possibility.
