Many people work with their familiar spirits through meditation, trance work, journeying, astral work, some people form a connection to the extent that they can sense the energy of their familiar spirit and work with them this way.
I personally haven't heard of anyone using a Ouiji board, but I am sure that some people possibly do depending on the nature of the familiar.
Please be careful if you choose to use a oujii board. Many people don't believe in them or don't believe the damage they can do. If you do use one, remember it may not be who you're looking for that comes thru. Anything could pretend to be who you are looking for. Also, from what I've been taught, make sure you close the conversation or board when you're done. I've used a board once and never again. The way I communicate with spirits is just talk. Ask them questions and try to get them to leave a sign that they heard you or are there. Sometimes I smell perfume for my grandmother. My grandfather's scent is cigar smoke smell. Sometimes I smell flowers, sometimes I find pennies or small rocks. Sometimes I just get chills or get hot. I even feel them sit on the couch or even rub my arm or leg when I lie down. I'm protected,I think, from anything negative but it can still spook me. Good luck and God bless
