1. Is it realistic to expect this to work?

2. Will the sockets on the Child PCB fit properly onto the Main board SMD headers?




I know the sockets will be perfectly flat; they're 90deg and sitting on the PCB surface. I'm worried that the headers might be slightly out of alignment and cause mating problems.

I prefer to use separate headers for each function of the child board (if at all possible). Also, excessively long sockets are not easily accessible.
