Abstract

The present invention provides a package device for reducing the electromagnetic/radio frequency interference, which includes a first substrate with a shielding structure on the under surface of the first substrate, and an insulating layer on the shielding structure. The first substrate includes a through hole that is filled with the conductor therein. A plurality of lead-frames located on the bottom surface of the first substrate. A second substrate located above between the two lead-frames. Then, the molding compound encapsulated to cover the above structures to form a package device. Therefore, the shielding path of the package device is constructed of the plurality of lead-frames, the conductor within the first substrate, the shielding structure, and the grounded to discharge the electromagnetic/radio frequency out of the package device, thus, the electromagnetic/radio frequency interference for the package device can be reduced.
