I have a small PCB, about the size of a quarter and having a Bluetooth chip on it. I have 4 wires soldered to the board. 2 of which are for a 3.7 Volt battery connection and 2 are to connect a small loudspeaker.
All of my components (PCB, battery, loudspeaker) are going to be encased in a cloth band and worn on a persons ankle. I am worried that through repetitive movement, my soldered connections will get disconnected.
Is there a recommendation for further protecting the soldered connections. I feel like wrapping it in electric tape won't be enough. Is there some kind of latex coating I can use to either coat the soldered connections or even the entire board?
I've heard of conformal coating. Is that my solution? If so which type for my case?
