摘要: A multilayer wiring board 10 comprises a substrate having a plurality of layers of reinforced resin material 12,18,19,26,18′,19′,26′, a patterned conductive layer 28,28′ provided on at least one major surface of the substrate, a plurality of via holes 30,32,34,36 provided at least partly through the substrate, and a plurality of signal carrying wires 20,20′. The signal carrying wires 20,20′ are provided between at least two of the layers of reinforced resin material 12,18,19,26,18′,19′,26′. The signal carrying wires 20,20′ can be embedded in a resin layer 21,21′, and the resin layer 21,21′ sandwiched between a pair 18,19,18′,19 of the layers of reinforced resin material. The reinforced resin material 12,18,19,26,18′,19 is preferably a fiber reinforced resin material, such as a glass fiber reinforced epoxy or polyimide material. In some applications, a constrained core 22,24,22′,24′, e.g., a copper/ molybdenum/copper laminate, can be provided between a major surface of the substrate and the pair 18,19,18′,19 of reinforced resin layers sandwiching the signal carrying wires 20,20′. The board 10 can be used in a multilayer wiring package wherein a plurality of integrated circuit chips are mounted on a major surface of the board 10. Applications include digital, high-speed digital and RF interconnects.

摘要: A high frequency coaxial interconnection solder ball grid array produces a low loss, reproducible electrical interconnection at the circuit board level for mounting one or more high frequency components, such as high frequency IMA modules. Since the coaxial interconnection ball grid array can be and is generally implemented as part of a larger ball grid array, high frequency signal generation, signal reception and digital processing can be combined in a single electronic component, such as a circuit board. A coaxial-like interconnection is formed from a plurality of solder balls configured in a three-by-three square array. The coaxial interconnection solder ball grid array includes a single centrally disposed solder ball for interconnecting with a centrally disposed conductor of a coaxial line and a plurality of solder balls surrounding the single centrally disposed solder ball, some balls of which interconnect with a coaxial ground shield of the coaxial line. When soldered together, the centrally disposed solder ball and the central conductor of the coaxial line have the appearance of a rod with a diameter having a standard 50 ohm impedance. The outer conductive shield or ground signal path of the coaxial line is connected with multiple solder balls, to achieve a lower inductance ground-to-ground connection.
