Patent number: 9807890Abstract: The present disclosure is related to electronic modules for electronic components and methods for manufacturing the same. In one embodiment, an electronic module is formed using a first substrate having a first component area and a second substrate having a second component area. One or more electronic components may be attached to both the first component area and the second component area. The second substrate is mounted over the first substrate such that the second component area faces the first component area. An overmold covers the first component area and the second component area so as to cover the electronic components on both the first component area and the second component area. In this manner, the number of electronic components within the electronic module that can be mounted on an area of a printed circuit board (PCB) is increased.Type: GrantFiled: May 31, 2013Date of Patent: October 31, 2017Assignee: Qorvo US, Inc.Inventors: Thong Dang, Mohsen Haji-Rahim, Joseph Byron Bullis

Patent number: 7732253Abstract: The present invention provides a unique way of connecting a flip-chip die to a substrate. Initially, metallic posts are formed on the flip-chip die and solder bumps are placed on the substrate where the metallic post will ultimately connect to the substrate. The tip layer of flash gold, tin, or other wettable electroplated material is applied to the tips of the metallic posts to prevent oxidation and enhance wettability. The sides of the metallic posts are allowed to oxidize to reduce wettability. To attach the flip-chip die to the substrate, the flip-chip die is initially positioned over the substrate, such that the metallic posts align with and come into contact with the solder bumps. Once the flip-chip die is in place over the substrate, the substrate and the flip-chip are heated to cause the solder bumps to reflow and bond to the tip layers of the metallic posts.Type: GrantFiled: August 14, 2006Date of Patent: June 8, 2010Assignee: RF Micro Devices, Inc.Inventors: T.
