IC Sockets & Adapters

Board-to-Board Connectors

Bandwidth Up to 94 GHz
Pitch Range 0.2mm – 2.54mm
Height Range 0.25mm – 5mm
Contact Technologies Elastomer, Spring Pin, Pin-Clip
Contact Resistance <30 mΩ
Development No hard tooling required

Board-to-board connectors in elastomer, spring pin, and pin-clip technologies running up to 94 GHz in a compact footprint, with laser-and-laminate construction for fast prototype and production turnarounds without hard tooling.

Three contact technologies cover the board-to-board interconnect range.

Elastomer connectors give the shortest electrical paths with low inductance and two-sided compliance — silver particles in silicon column buttons on a non-conductive polymer substrate. Highest bandwidth of the three at 94 GHz, −55°C to +160°C, with coaxial configurations for impedance matching and support for both board-to-board and flex-to-board layouts.

Spring pin connectors run 1mm to 5mm heights across 0.3mm to 1.27mm pitch, with stamped or precision screw-machined contacts in laser-cut laminated housings that allow custom contact placement without hard tooling. 8A per pin, −55°C to +180°C.

Pin-clip (male/female) connectors mate and unmate between mother and daughter boards at half the mating force of conventional connectors, over a 4.5mm gold-plated path from male pin top to female solder ball. 1mm and 0.8mm pitch, lead and lead-free solder ball types, qualified to MIL-STD environmental tests for automotive, military, communication, and industrial applications.

Overview

Ironwood’s board-to-board connectors support prototype and production applications across three contact technologies: elastomer for maximum bandwidth, spring pin for flexible height and high endurance, and pin-clip for mate/unmate applications. They serve automotive, military, communication, and industrial customers. Laser-and-laminate construction means custom configurations are built without hard tooling; see the delivery FAQss below for lead times.
