Abstract
Aspects of this disclosure relate to methods of selectively shielded radio frequency modules. A radio frequency module can be provided with a radio frequency component and an antenna. A shielding layer can be formed over a portion of the radio frequency module such that the radio frequency component is shielded by the shielding layer and the antenna is unshielded by the shielding layer.
Claims22
A method of selectively shielding a radio frequency module, the method comprising:
- providing a radio frequency module including a radio frequency component, an antenna, and wire bonds disposed between the radio frequency component and the antenna;
- masking a first portion of the radio frequency module over the antenna with a masking material such that a second portion of the radio frequency module over the radio frequency component is not covered by the masking material;
- and
- after said masking, forming a shielding layer over the radio frequency module such that (i) the radio frequency component is shielded by the shielding layer and the antenna is unshielded by the shielding layer and (ii) the shielding layer is in contact with the wire bonds to provide shielding between the radio frequency component and the antenna.
A method of selectively shielding a radio frequency module, the method comprising:
- providing a radio frequency module including a radio frequency component and an antenna;
- masking a portion of the radio frequency module over the antenna with a masking material over a molding material such that an other portion of the radio frequency module over the radio frequency component is not covered by the masking material;
- forming a conductive layer over the portion of the radio frequency module and the other portion of the radio frequency module;
- and
- removing the masking material such that a shielding layer is over the radio frequency component and the antenna is unshielded by the shielding layer, the shielding layer including conductive material of the conductive layer.
