Patent number: 8359739Abstract: In one embodiment, a meta-module having circuitry for two or more modules is formed on a substrate, which is preferably a laminated substrate. The circuitry for the different modules is initially formed on the single meta-module. Each module will have one or more component areas in which the circuitry is formed. A metallic structure is formed on or in the substrate for each component area to be shielded. A single body, such as an overmold body, is then formed over all of the modules on the meta-module. At least a portion of the metallic structure for each component area to be shielded is then exposed through the body by a cutting, drilling, or like operation. Next, an electromagnetic shield material is applied to the exterior surface of the body of each of the component areas to be shielded and in contact with the exposed portion of the metallic structures.Type: GrantFiled: December 7, 2007Date of Patent: January 29, 2013Assignee: RF Micro Devices, Inc.Inventors: Dan Carey, Jeffrey Scott Walker, Gary D.

Patent number: 6825560Abstract: The present invention relates to electrically attaching a surface mount device to mounting structure via their respective contact pads using an attach material, such as solder or conductive epoxy, which includes a filler material. In general, the filler material is relatively solid and granular shaped, wherein the diameter of the filler material controls a mounting distance between the surface mount device and the mounting structure. The filler allows a desired distance to be maintained during initial placement of the surface mount device and any subsequent reheating.Type: GrantFiled: May 22, 2003Date of Patent: November 30, 2004Assignee: RF Micro Devices, Inc.Inventors: Jeffrey Scott Walker, Joseph Byron Bullis
