When Signal Integrity and Density Matter

Carlisle Interconnect Technologies (CarlisleIT) CoreHC™ is a high-performance multi-port interconnect system with both 2.5 mm and 4 mm spacing pitch. It offers excellent signal integrity for complex layouts and crowded PCBs used in a variety of applications. It is a cost-effective solution optimized for applications with demanding bandwidths up to 65 GHz.

CarlisleIT’s unique compression force design results in easier and rapid connectivity of high-frequency signals on the board. Since there are configurations using single or multiple channels, board size can be optimized accordingly.

The vertical mount-attach solution eliminates the board-side connector or interposer by offering a direct connection of signals between traces and pads on PCB footprint and compression pins on cable assembly. Board-side interposer is required for edge mount-type solution. Optimized footprints and layouts are available upon request.

The 2.5 mm solution is designed for demanding bandwidths up to 65 GHz. Standard products are available in single and dual row 2, 4, 6, 8 and 10-channel configurations.

Features & Benefits

Feature Customer Benefit
DC to 65 GHz Frequency range Supports a variety of applications today and emerging applications of tomorrow, reducing overall cost
Board footprint compatibility Design for use with both Coplanar Wave Guide (CPW) and Stripline PCB traces
Multiple board-to-board solutions 8 mm to 20 mm stack-up height in 2 mm increments to meet certain height restrictions
One-piece interface for vertical-mount type Saves time and reduces costs because no soldering to the board is required; only PEM nuts are used for installation and removal
