I have a embedded computer design which uses a low profile micro sd card socket as an extra option in addition to an on board solid state disk as storage/booting mediums. In manufacture the board is coated with conformal coating but i'm in a bit of a pickle regarding the SD card socket and the coating.
The SD card socket should be masked i assume before coating is applied, otherwise it may seep into the connector i suspect, but then i am creating a bit of a weakness against moisture. It seems this particular weakness is inherent to the SD card socket.
Has anyone found a good solution for this on a professional level, or are these two things simply incompatible (card sockets and coatings/materials). Have you operated exposed sd card sockets in moist environments with a long durability ?.
What i'm mostly afraid of is that if i have the pin connections protruding from the chassis coated, the coating will seep into the socket. Expecting workers to be careful while hand coating stuff like this is probably too much and asking for trouble later.
