Board to board connectors are used to connect PCB, electronic
components that contain a conductive pattern printed on the surface of the
insulating base in an accurate and repeatable manner. Each terminal on a board to board connector is connected to a PCB. A BTB includes housing and a specific
number of terminals. The terminal is made from a conductive material and plated to improve conductivity and antirust. Terminals transmit
the current/signal between PCBs connected by Board to board connectors; the housing is made of
insulating material (mostly plastic).
