Abstract

A handheld communication apparatus includes a metallic insert molding member, a circuit board and a shielding frame. The metallic insert molding member includes a metal plate. An electronic component is mounted on the circuit board. The shielding frame defines opposite first and second openings, wherein the shielding frame is bonded to the metal plate of the metallic insert molding member at the first opening, thereby forming a shielding case. The electronic component on the circuit board is inserted into the second opening of the shielding frame to be shielded by the shielding case.

Claims
