Abstract:
An electronic assembly (100) includes a first substrate (102) and a second substrate (122). The first substrate (102) includes a first surface having a first plurality of conductive traces (106) formed on an electrically non-conductive layer (104). The second substrate (122) includes a first surface having a second plurality of conductive traces (126) formed thereon and a second surface having a third plurality of conductive traces (124) formed thereon. A first electronic component (132) is electrically coupled to one or more of the plurality of conductive traces (126) on the first surface of the second substrate (122). At least one of a plurality of conductive interconnects (108) is incorporated within each solder joint that electrically couples one or more of the conductive traces (124) formed on the second surface of the second substrate (122) to one or more of the conductive traces (106) formed on the first substrate (102).
Abstract:
The present invention provides a method for producing an electronic assembly and an electronic assembly (10, 100, 200, 300, 600) with an integrated cooling system for dissipating heat. The electronic assembly comprises a base (18, 218, 318, 618); and at least one electrical component (30, 230, 330, 630) attached to the base (18, 218, 318, 618). The base (18, 218, 318, 618) defines an integrated cooling system having a fluid channel (11, 211, 311, 611) spanning within the base (18, 218, 318, 618) and at least one heat exchanger (12, 13) in heat communication with the fluid channel (11, 211, 311, 611). The integrated cooling system may further include a pump (14) attached to the base (18, 218, 318, 618) for directing the flow of the fluid within the fluid channel (11, 211, 311, 611), and a port (16) in fluid communication with the fluid channel (11, 211, 311, 611) for receiving fluid from an external source.

Abstract:
A circuit board assembly (30) that makes use of a low-temperature co-fired ceramic (LTCC) substrate (10), and a process for producing the assembly (30). The substrate (10) contains at least first and second regions (32,34) formed by a plurality of first ceramic layers (36) and at least one second ceramic layer (38), respectively, that are superimposed and bonded to each other. Conductor lines (22) are present on at least some of the first ceramic layers (36) so as to be between adjacent pairs of the layers (36). Electrically-conductive vias (16) electrically interconnect the conductor lines (22) on different first ceramic layers (36), and a surface-mount IC device (12) is mounted to the substrate (10). The first ceramic layers (36) are formed of electrically-nonconductive materials, while the one or more second ceramic layers (38) contain thermally-conductive particles dispersed in a matrix of electrically-nonconductive materials, such that the one or more second ceramic layers (38) are more thermally conductive than the first ceramic layers (36).
