Abstract:
This invention discloses a method for manufacturing an inductor by first press punching a first and a second layer of conductive plates into a first and second coil layers with a first and second inductor lead layers as single integrated layers. The manufacturing process further includes a step of overlapping and connecting the first and second coil layers to form an inductor. In a preferred embodiment, process of manufacturing further includes a step of mixing epoxy to bond with a highly magnetic material and pressure molding the bonding magnetic material around the coil layers to form an inductor.
Abstract:
A structural configuration and manufacture method is applied to manufacture electronic circuits on a ceramic substrate including capacitor and inductors for filters. The electronic circuits have strong bonding to securely adhere to the SOG-coated substrate when the SOG is cured at an elevated temperature supplemented with high nitrogen flow during the curing process. The SOG coated ceramic substrate shows excellent layer compatibilities during temperature variations because reduced differences of thermal coefficients between different layers.
Abstract:
The present invention discloses a resistor supported on a metal plate composed of a low temperature coefficient of resistance (TCR) metallic material. The resistor includes at least two electrode columns composed of the low TCR metallic material disposed on the metal plate. The resistor further includes at least an electrode layer disposed on each of the electrode columns to form an electrode for each of the electrode columns. In a preferred embodiment, the low TCR metallic material composed of the metal plate further comprises a nickel-copper alloy. In another preferred embodiment, the electrode layer disposed on each of the electrode columns further comprises a copper layer and a tin-lead alloy layer on each of the electrode columns. In another preferred embodiment, the electrode columns disposed on the metal plate having a precisely defined position for providing precisely defined resistance for the resistor ranging between one milli-ohm to one ohm.
Abstract:
The present invention discloses a substrate structure for supporting a thin film with specific temperature coefficient of resistance (TCR) thereon. The substrate structure includes a substrate composed of a borosilicate glass. The substrate further includes an interface layer of LaSiONx covering a top surface of the substrate. The substrate supports the thin film includes a platinum thin film thereon. The substrate structure further includes an adhesion anchoring seam disposed as a bonding seam interfacing the thin film to the substrate for securely attaching the thin film to the substrate therein. The bonding seam is disposed on a boundary edge of the thin film and includes a nickel-chromium alloy anchor seam disposed on the boding seam. In a preferred embodiment, the substrate structure includes a protective layer covering and protecting the substrate structure thereunder. In another preferred embodiment, the substrate structure further includes electrodes for electrically connecting to the thin film with the specific TCR for providing an electrical voltage thereto.
