摘要:
An electric device comprises a substrate (SU) as a carrier and at least two chip components mounted thereto. In the top surface of the substrate a recess (RC) is formed. One or more chip component (BC) is mounted to the bottom surface of the recess referred to as buried chip component. One or more top chip component (TC) is mounted to the top surface of the substrate to cover at least to some extend the recess and the buried chip component. Device pads (PD) are arranged on the bottom surface of the substrate. Each of them is electrically interconnected with one or both of the chip components.

A method for manufacturing a microwave or radio frequency (RF) device (300) including stacked printed circuit boards (PCBs) (102, 152) mounted on a flexible PCB (206) having at least one ground plane and signal terminals is disclosed. Each of the stacked PCBs includes through-holes (120) the sidewalls of which are coated with a conductive material. The first PCB and the second PCB are bonded to the flexible PCB, the first PCB spaced apart from the second PCB exposing a bend portion of the flexible PCB. Microwave components (110, 112, 154, 156) are mounted on the flexible PCB within the through-holes, such that signal terminals of the components bond to respective signal terminals of the flexible PCB. A conductive cover (132, 228) is mounted on the PCBs such that the cover is in electrical contact with the ground plane of the flexible PCB through the conductive material, forming shielding cavities around the components. The flexible PCB is folded such that the cover (132) of one PCB (102) faces the cover (228) of the second PCB (152). The flexible PCB includes striplines or microstrips that carry RF or microwave signals to the signal terminals.

In one embodiment, the package-on-package stacked microelectronic structure may comprise a first and a second microelectronic package, each comprising a substrate having at least one package connection bond pad formed on a first surface of each microelectronic package substrate, and each having at least one microelectronic device electrically connected to the each microelectronic package substrate first surface, wherein the first and the second microelectronic package are connected to one another with at least one package-to-package interconnection structure extending between the first microelectronic package connection bond pad and the second microelectronic package connection bond pad.
摘要:
Devices and methods for processing singulated radio-frequency (RF) units. In some embodiments, a device for processing singulated RF packages can include a plate having a plurality of apertures. Each aperture can be dimensioned to receive and position a singulated RF package to thereby facilitate processing of the singulated RF packages positioned in their respective apertures. In some embodiments, such a device can be utilized to batch process high volume of RF packages as if the RF packages are still in a panel format.
