A method and apparatus for making angled vias in an integrated circuit package substrate includes providing an integrated circuit package substrate having an upper surface and a lower surface. A first position is selected for a first via opening on the upper surface of the package substrate, and a second position is selected for a second via opening on the lower surface of the package substrate. A selected non-vertical angle is determined for forming an angled via through the first position and the second position. The angled via is formed through the first position and the second position at the selected non-vertical angle.

In one embodiment, an apparatus for interconnecting electronic components includes a dielectric portion having a first surface and a second surface. A first terminal is disposed on the first surface of the dielectric portion for connection to a first electronic component. A second terminal is disposed on the second surface of the dielectric portion for connection to a second electronic component.

Abstract:
A method and structure are provided for implementing enhanced electronic packaging and printed circuit board (PCB) layout. A diagonal via is formed at a selected angle between a first side and an opposite second side of a printed circuit board at a selected printed circuit board location. The diagonal via is plated with an electrically conductive material. Diagonal vias are used to interconnect between a high-density pitch on the first side and a larger pitch on the opposite second side of the printed circuit board. The diagonal vias can be used to selectively interconnect electrical patterns of selected layers and eliminate the use of blind and buried vias.

Methods are provided for making plated through holes usable for inserting and attaching connector probes. In a first method, a curved plated through hole is formed by bonding curved etchable wires to a first substrate, plating the wires with a non-etchable conductive material, encasing the plated wires with a dielectric material to form a second substrate, planing the second substrate to expose the etchable wire, and etching the wires to leave plated through holes. In a second method, wires coated with a first etchable layer are initially bonded to a substrate, a second non-etchable plating layer is then applied over the first layer, and the first layer is etched away leaving plated through holes with wires disposed inside. In a third embodiment, a layer of masking material is initially deposited on a substrate and etched to form holes which are filled with a sacrificial fill material, the masking material is then removed, the fill material plated, grinding is performed to remove some plating to expose the fill material, and the fill material is then etched away leaving plated attachment wells. Probes may be attached to the plated through holes or attachment wells to create resilient spring contacts to form a wafer probe card assembly. A twisted tube plated through hole structure is formed by supporting twisted sacrificial wires coated with the plating material in a substrate, and later etching away the wires.

Abstract:
The invention relates to a card-shaped data carrier comprising a card body (1) having an antenna (3), and a chip module (2) containing an integrated circuit (10) and inserted into a gap (5) in the card body (1). The electric connection between the antenna (3) and the chip module (2) is effected via depressions (11) in the terminals (4) of the antenna (3). For producing the inventive data carrier one provides the card body (1), in which the antenna (3) is at least partly embedded, with a gap (5). The terminals (4) of the antenna (3) are exposed by removing the superjacent card material whereby part of the material forming the terminals (4) is also removed. The chip module (2) is inserted into the gap (5) and for example glued to the card body (1) with a thermally activable adhesive (6), an electric connection being formed between the chip module (2) and the antenna (3) for example by means of a conductive adhesive (7) previously applied to the exposed terminals (4) of the antenna (3). In the preferred embodiment the material removal on the terminals (4) of the antenna (3) is effected such that a bevel arises.

An electronic package assembly for electrical interconnection between two electronic modules having differing conductive array parameters is disclosed. The electronic package assembly includes two electronic modules, providing between the two electronic modules an interposer having a top surface and a bottom surface; a first set of conductive arrays having a first conductive array parameter on the top surface, and a second set of conductive arrays having a second conductive array parameter on the bottom surface, the second conductive array and the first conductive array having differing parameters. A plurality of conductors traverses a thickness of the interposer of the electronic package assembly, with the conductors including a conductive material optionally coated with a dielectric material, the conductors having a first end at the first conductive arrays and a second end at the second conductive arrays, whereby the conductors connecting the first and second conductive arrays therein are adapted to spatially transform the differing parameters to provide an electrical interconnection. A conductive matrix surrounds the conductors of the interposer of the electronic package assembly. The first set of conductive arrays includes the same conductive array parameters as a first electronic module and the second set of conductive arrays includes the same conductive array parameters as a second electronic module.
