Hello Technet!
Wondering what other people are doing with this dilemma.
We have had several customers design in pre-built RF modules on their boards. I totally get why, it is a pre-built, FCC approved, easy solution - the fastest way to get a good Wi-Fi or bluetooth solution.
Where things go off the rails for me are where this is used in a high humidity application (e.g. a marine setting). We strongly prefer to wash boards, we can build no-clean if needed but I'd prefer not to for an on the water use. But the part a customer has designed in specifically says not to wash it (it has an EMI shield, so they are properly concerned with water entrapment).
So - would you:
- build it no-clean?
- leave the part off, build and wash as usual, install RF module later using no-clean?
- wash it (and maybe bake it to dry it out)?
- ????
