A method for fabricating a conductive trace structure includes the steps: forming a first metal layer on a non-conductive substrate; removing a part of the first metal layer to expose the non-conductive substrate so as to form the first metal layer into a plating region and a non-plating region, the plating region being divided into at least two trace-forming portions and at least one bridge portion; forming a second metal layer on the plating region by electroplating the plating region using one of the trace-forming portions and the bridge portion as an electrode; and removing the bridge portion and the second metal layer formed on the bridge portion.

A printed circuit board includes a base insulating layer formed of a porous film. Conductor traces are formed on the base insulating layer formed of the porous film. A cover insulating layer is formed on the base insulating layer to cover the conductor traces. The porous film used as the base insulating layer has a reflectivity of not less than 50% for light of at least a part of wavelengths in a wavelength region from 400 nm to 800 nm.
Abstract:
A method for forming thin film conductors is disclosed. A thin film precursor material is initially deposited onto a porous substrate. The thin film precursor material is then irradiated with a light pulse in order to transform the thin film precursor material to a thin film such that the thin film is more electrically conductive than the thin film precursor material. Finally, compressive stress is applied to the thin film and the porous substrate to further increase the thin film's electrical conductivity.
Abstract:
This invention relates to the thermal management, extraction of light, and cost effectiveness of Light Emitting Diode, or LED, electrical circuits. An integrated circuit LED submount is described, for the packaging of high power LEDs. The LED submount provides high thermal conductivity while preserving electrical insulation. In particular, a process is described for anodizing a high thermal conductivity aluminum alloy sheet to form a porous aluminum oxide layer and a non-porous aluminum oxide layer. This anodized aluminum alloy sheet acts as a superior electrical insulator, and also provides surface morphology and mechanical properties that are useful for the fabrication of high-density and high-power multilevel electrical circuits.
