Patent attributes
An expansible interface for expanding different kinds of data from a primary printed circuit board (PCB) (1) to a subsidiary PCB (2), the primary PCB is fixed with board-to-board connectors (13, 14) and flexible printed circuit (FPC) connectors (11, 12), and the subsidiary PCB is fixed with the corresponding board-to-board connectors (23, 24) and the corresponding FPC connectors (21, 22). The board-to-board connectors are directly electrically connected with each other for transmitting a data that is not a Peripheral Component Interconnect (PCI) data from the primary PCB to the subsidiary PCB; the FPC connectors are electrically connected with each other via cables (31, 32) for transmitting the PCI data from the primary PCB to the subsidiary PCB.
