Abstract:
An example stretchable device is described that includes electrical contacts and an interconnect coupling the electrical contacts. The interconnect has a meander-shaped configuration that includes at least one nested serpentine-shaped feature. The interconnect can be conductive or non-conductive. The meander-shaped configuration can be a serpentine structure, providing a serpentine-in-serpentine configuration.
Abstract:
A metal interconnect structure ( 100 ) comprising a bond pad ( 101 ), which has copper with at least 70 volume percent composed of crystal grains expanding more than 1 mum in their main direction, and 30 or less volume percent composed of crystal grains, which expand less than 1 mum in their main crystal direction. A body ( 102 ) of tin alloy is in contact with the bond pad.
Abstract:
The inventions relates to a method of manufacturing a circuit incorporating a solid state light emitting component (50), the method comprising providing an insulating layer (8), producing at least one through hole (20) in the insulating layer (8), providing a conductive layer (10), bonding a main surface (24) of the conductive layer (10) to the insulating layer (8), and positioning at least one solid state light emitting component (50,100) in the hole (20) of the insulating layer (8) and connecting this component to the conductive layer (10).
Abstract:
A manufacturing method of a multilayer substrate (101) is provided, comprising: laminating single-sided conductor patterned films (21, 21 a, 21 b), each of which has a resin film (23), a conductor pattern (22, 22a) formed only on a single side of the resin film, and a via hole (24, 24a, 24b) formed at a predetermined location and filled with an interlayer connection material (50); and adhering the single-sided conductor patterned films to each other to form a multilayer substrate; wherein an arbitrary two of single-sided conductor patterned films (21 a, 21 b) are laminated so that surfaces thereof on which the conductor patterns (22) are not formed face with each other, while remaining single-sided conductor patterned films (21) are laminated in such a manner that a surface on which the conductor pattern (22) is formed and a surface on which the conductor pattern (22) is not formed face with each other, whereby electrodes (32, 37) are formed by the conductive patterns (22) at both sides of the multilayer substrate (101).
Abstract:
The invention provides methods to mass laminate and interconnect high density interconnect circuit layers fabricated through parallel processing. Invention methods employ an inside-out interconnection strategy that eliminates plating of vias and provides defect-free outer circuit layers. Conductive paste and via layers are also key features of the invention.
Abstract:
A manufacture method for a surface mounted power LED support comprises steps: providing a wiring board (1) having both sided metal layers (11, 12); forming a hole (13); setting a metal layer (131) in the surface of the hole; thickening the metal layer (11, 12) of the wiring board; etching the metal layer of the wiring board; cutting the wiring board to form single support unit. A surface mounted power LED support comprises a both sided wiring board (10, 11, 12), a hole (13) formed in the wiring board and wiring layers (16, 17) set on the surface of the wiring board. The invention can increase the heat dissipation effect of the chip.
