Interposers
The interposer, or contact array, is the heart of the connector. It is also IDI’s specialty – as the world’s leading spring contact probe manufacturer we are uniquely positioned to bring the advantages of this contact mechanism to life.IDI is able to

bring our customers the most benefi t when providing a total solution, but we can provide our technology at any level. Loose contacts, simple interposers, cabled mating halves, and complex docking solutions are all within our portfolio.
Insertion Life
Spring contact probes are driven by helical coil springs. This, combined with IDI’s advanced materials and plating expertise, allows us to offer connectors which are capable of hundreds of thousands of insertions when properly specified. Even wiping interconnects can be made to withstand millions of rotations.
Signal Integrity
Bandwidths of 20 GHz and data rates of 12 Gb/S are possible with simple pin field interposers. This is due to IDI’s remarkably short contacts and our expertise in predicting their behavior in application.
Interposers may also be made coaxial through the use of precision-machined insulators and metal interposer bodies. IDI is the inventor of the independent coaxial spring contact probe, featuring a spring-loaded shielding plunger; this may be added to a connector to provide one or more discrete high speed lines.
DC Stability
Through innovative design features such as our patented Eccentric Drill, IDI’s interposers maintain low and consistent contact resistance through their long insertion lives.
Maintaining peak performance through the required life of the interposer requires a careful selection of biasing features. IDI maintains a staff of dedicated experts who can guide you to the optimal contact engine for your application.
Properly specified interposers can withstand the intense shock and vibration associated with aerospace and military applications, maintain-ing reliable contact without fail even when launched onboard munitions.
IDI’s interposers can be designedto take advantage of spring contact probes’ surprising current carrying capacity. Individual contacts are capable of handlingas much as 30 Amps in free air; combined with IDI’s advanced thermal analysis capabilities, connectors can be designed which can handle substantial amounts of power safely.
