Compliant-pin Connectors for Harsh Environments
September 7, 2007 |Estimated reading time: Less than a minute
MILPITAS, Calif. An enhanced line of smooth sliding, fast-holding press-fit compliant-pin connectors are available from Onanon Inc. The solderless connectors suit harsh-environment electronics.
By re-engineering the curvature of the hole and pin using an automated close-tolerance milling manufacturing method, contact force reportedly is more sufficient to maintain contact in harsh-environment electronics. Limiting the insertion force allows easy insertion of connectors with a large number of pins. It also eliminates particulate debris from being scraped from the plated-thru-hole and increases the number of reinsertion cycles to more than a thousand, claims the company.
Compliant-pin technology is said to ease and reduce the cost of PCB manufacturing, eliminating machines, time, cost, and thermal stresses of soldering. Connectors can be manufactured using a PCB platform, and can be part of an interconnection or plug-in modules designed to modify a board's function. Plug-in and interconnection platforms were designed using terminating resistors or decoupling capacitators; other platforms host complex configurations using microcontroller or analog ICs.
The connectors work under shock and temperature, and can deliver DC to 10 GHz, with pin-to-pin capacitance down to 1 pF, inductance down to 2 nH, and connection resistance of less than 10 mΩ.
