Abstract:
1. A twin-substrate wireless electronic module comprising: a main substrate having a first surface, a second surface opposite to said first surface, a plurality of first solder pad units formed on said first and second surfaces, and a conductor unit formed on said second surface and connected electrically to said first solder pad units, said main substrate being formed with a notch that extends from said first surface through said second surface; a plurality of integrated circuit chips surface-mounted on said first and second surfaces of said main substrate at said first solder pad units, one of said integrated circuit chips that is disposed on said first surface of said main substrate being a transceiver integrated circuit chip; a frame substrate having a first frame surface, a second frame surface opposite to said first frame surface, a surrounding frame surface interconnecting said first and second frame surfaces, and a second solder pad unit provided on said first frame surface, said first frame surface being surface-mounted on said second surface of said main substrate such that said conductor unit is connected electrically to said second solder pad unit, and such that said surrounding frame surface cooperates with said second surface of said main substrate to form a receiving space that receives said integrated circuit chips on said second surface of said main substrate therein, said first frame surface further having a filter-mounting area aligned with said notch in said main substrate and provided with a filter pad unit that is connected electrically to said second solder pad unit; a filter surface-mounted on said filter-mounting area of said first frame surface at said filter pad unit and accommodated in said notch of said main substrate; and a shield member mounted on said first surface of said main substrate for shielding said transceiver integrated circuit chip and said filter.
