Spring
Contact
Assemblies
Signal Integrity’s expertise in design, tooling, and assembly of miniature mechanical components makes us a valued partner with OEMs on small dimension custom contact and interconnect assemblies in the millimeter scale. We have many years experience designing sub assembly contacts and components for commercial test equipment OEM probes and dense interconnect contactors.
A Quality Product You Can Trust
We are a qualified US Government supplier and can perform sub contract design manufacturing and assembly for your challenging, miniature spring-driven contact assemblies, for military and research applications.
These projects include custom compliant interconnects for non-linear contact to circuit board modules, cable to probe compliant connectors for back plane and remote test probing, and various ATE and module probe interfaces for package and wafer test.
Key Applications
Signal Integrity’s spring probes are sub-assembly components in broad line applications beyond just test sockets.
01
EV and Charging Power Components
Signal Integrity’s clad barrel technology and multi spring architecture allows us to design and implement fixtures and sockets with high amounts of continuous and pulsed currents. This is well suited in the power, EV, charging, and energy storage socket applications. We have developed connector power block modules for TO and STO devices in the high current applications for EV and charging systems. These power block modules are integrated into sockets to deliver very high pulsed currents from 600 to 1000 amps for short duration pulses
02
Board-to-Board Connectors
Much like test sockets, Signal Integrity’s extensive library of compliant spring probe components lets us create almost any configuration board to board or module connector configuration. We can create board to board connectors that operate at greater than 40 GHz and can conduct over 8 amps per pin. These connectors can be very dense with grid pitches down to 0.2 mm and can also be designed as pitch converters for constructing PCB board interconnects from larger to tighter pitches.
Signal Integrity has pins and design models available for board to board interconnects that can operate with a compliance of 0.25 mm and with a minimum total height from 1.1 mm to 2.0 mm.
03
ATE Connectors
Signal Integrity has a line of probes ideal for commercial and custom ATE hardware. These pins can be tuned to your application to meet the power, current, frequency, and contact resistance your test head needs. We are experts in this area and can develop the proper pin, housing, and cabling to fit your system. We deliver full simulations and 3D modeling with these products.

ITAR Control Spring Assemblies
Signal Integrity’s expertise in small spring design and an ability to adapt micro welding and advanced soldering on stainless steel has led to successful contract bid windsor sub assemblies in the aerospace connector and armament space.
