A SIM card connector includes a rectangular housing defining a number of contact passageways on opposite edges thereof, and a number of contacts retained in corresponding contact passageways of the housing. The rectangular housing comprises two opposite longitudinal sides and two opposite lateral sides and defines a recessed portion in a bottom face thereof through the longitudinal sides and the lateral sides. The recessed portion can accommodate a variety of electronic components and hot air can flow into the recessed portion from the longitudinal sides and the lateral sides of the housing to melt slug solders thereby securely connecting the electronic components to a PCB when the connector is mounted to the PCB.
