    摘要: A pinning process including the steps of gold-plating through-holes in a laminate carrier and crimping a gold or gold-plated pin located in the through-holes to form a pin head on the top and a pin bulge on the bottom of the laminate carrier to produce a plastic pin grid array. A variety of mechanical forming processes may be employed to form the pin heads and pin bulges and cause the pin to at least partially, and preferably substantially, fill and contact the gold-plated through-hole including swage pinning, impact pinning, and double-die pinning operations. By combining the steps of gold-plating through-holes of a laminate carrier and using a mechanical pinning process to crimp a gold or gold-plated pin in the through-holes, a reliable mechanical and electrical connection may be established between the pin and the metal lines both inside and on the surface of the laminate carrier without the need for lead-containing solders and pastes.

    摘要: A printed circuit board is provided comprising a substrate, a conductor on the surface of the substrate, and an electronic component mounted on the conductor. The printed circuit board includes a first thermally conductive layer within the substrate and a second thermally conductive layer on a portion of the surface of the substrate and spaced from the electronic component. The electronic component is thermally coupled to the second thermally conductive layer by a thermally conductive aperture positioned within the substrate and connected to the conductor and the first thermally conductive layer. The first thermally conductive layer is connected to the second thermally conductive layer by a plurality of apertures also positioned in the substrate. Another printed circuit board is also provided comprising a first plurality of laminate dielectric layers, a conductor on a surface of the first plurality of laminated dielectric layers, and an electronic component mounted on the conductor. The printed circuit board includes a second plurality of laminated dielectric layers connected to the first plurality of laminated dielectric layers by a flexible web. The flexible web includes a first thermally conductive layer positioned within the first plurality of dielectric layers. A thermally conductive aperture thermally connects the electronic component to the first thermally conductive layer. A plurality of thermally conductive apertures is positioned within the second plurality of dielectric layers and thermally couples the first thermally conductive layer to a second thermally conductive layer which is included on a portion of a surface of the second plurality of dielectric layers and spaced from the electronic component. The flexible web portion thus allows positioning of the second thermally conductive layer in a plane remote from the electronic component when it is positioned in a confined space.

    摘要: A method and structure for forming a metalized blind via. A dielectric layer is formed on a metallic layer, followed by laser drilling a depression in the dielectric layer such that a carbon film that includes the carbon is formed on a sidewall of the depression. If the laser drilling does not expose the metallic layer, then an anisotropic plasma etching, such as a reactive ion etching (RIE), may be used to clean and expose a surface of the metallic layer. The dielectric layer includes a dielectric material having a carbon based polymeric material, such as a permanent photoresist, a polyimide, and advanced solder mask (ASM). The metallic layer includes a metallic material, such as copper, aluminum, and gold. The carbon film is in conductive contact with the metallic layer, and the carbon film is sufficiently conductive to permit electroplating a continuous layer of metal (e.g., copper) directly on the carbon film without need of an electrolessly plated layer underneath the electroplated layer. The laser drilling is accomplished using a laser radiation having a wavelength between about 180 nanometers and about 600 nanometers. The depression may have any cross-sectional shape and any spatial distribution of depths. As an example, the depression may include a blind via, a rectangular channel, or a combination thereof.
