Guard structure for electronic component, has information-storing chip electrically connected with security guard chip that is connected with electric circuit in circuit board, where chip and security guard chip incorporate chip module

摘要

The structure has a circuit board (10) i.e. multilayer board, provided with an electric circuit and a cavity (11). A set of electrode contacts (12) is arranged with the electric circuit in the circuit board and electrically connected at a periphery of the cavity. A chip module is arranged on same side of another circuit board (20). An information-storing chip and a security guard chip incorporate the chip module. The information-storing chip is electrically connected with the security guard chip that is connected with the electric circuit in the latter circuit board.
