<p>A high-speed, high pin-out chip carrier package (10) for interconnecting at least one LSI or VLSI chip to a circuit pack is disclosed. The package includes a ground plane (19), a power plane (20), and at least one signal layer (15, 16, 17, 18) containing plural conductors therethrough. Layers (85) of dielectric material separate adjacent conductive layers, (15, 16, 17, 18, 19, 20). By controlling, in design, the width of each signal conductor and its distance to the nearest ground (19) or power plane (20), the package is impedance-matched to the circuit pack. Plural plated-through holes (21) are disposed through the package for electrically interconnecting the signal conductors, the ground plane (19), and the power plane (20) to the circuit pack, and are arranged in a pattern to reduce inductive noise.</p> |
