Onanon’s innovations in compliant pin technology are made possible by its highly automated, close-tolerance milling manufacture

Onanon has released smooth sliding, fast holding press-fit compliant pin connectors. Compliant pin technology has stood the test of time by providing press-fit connections that withstand thermal shock, vibration and humidity. Onanon has improved this 20-year old technology so that the compliant pins slide smoothly into plated thru-holes, a major breakthrough in this tried and tested green technology that makes it even more cost-effective and environmentally friendly.
These devices can be used in the harshest environments and in the most delicate devices.

They are solderless and meet RoHS standards.

Onanon compliant pin connectors can be selected from a quick order catalogue or custom made.

Onanon’s innovations in compliant pin technology are made possible by its highly automated, close-tolerance milling manufacture.

‘In the prior technology, an oval ‘eye of the needle’ hole was punched into a pin’.

‘When this pin is inserted into a plated thru-hole, the ‘eye of the needle’ compressed with a spring force that held the pin snug’, said Dennis Johnson, CEO of Onanon.

‘Now, by precisely engineering the curvature of the hole and pin, we can guarantee that the contact force is more than sufficient to maintain contact in the harshest environments, but not so great as to produce excessive insertion force’.

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 over a thousand.

The rapid increase in chip performance, density, mixed signal level type and frequency has placed increasing demands on printed circuit board (PCB) manufacturers.

Rapid advances in technology leave a trail of obsolescence.

Redesigning and testing a new board to stay on the cutting edge can be expensive.

Onanon compliant pin technology simplifies and reduces the cost of PCB manufacture.

The devices remove the time, cost and thermal stress of soldering.

All the problems associated with solder such as residue, bridging, cracked or cold solder joints are also eliminated.

Connectors can be manufactured with a PCB platform.

These connectors can be part of an interconnection or plug-in modules designed to modify a board’s function.

Both plug-ins and interconnection platforms have been designed and engineered using only terminating resistors or decoupling capacitors, while other platforms have hosted more complex configurations using microcontroller or analogue chips.

Onanon’s compliant pin products provide production flexibility to manufacturers.

Mass termination of connectors is common in the telecommunications industry.

A press can inserts a connector with up to a thousand pins.

Pin-stitching systems can apply discreet reeled pins one at a time.

This latter process has the advantage of a flexible insertion pattern that can change to offer different options in the same PCB.

Onanon delivers custom headers according to the customer’s specification.

These headers can be automatically inserted at the factory or manually replaced in the field using ordinary tools.

Customised connector products can be engineered and manufactured with any pin size, shape or pattern and placed in a variety of insulators.

Since there are no set-up charges, modification can be made on connectors with just-in-time delivery to accommodate new board innovations.

Onanon assembles custom connectors with a fully automated process.

Pins or contacts are installed to a precise depth into machined insulators.

Straight and secure installation in the plastic, ceramic or ferrite substrate is insured.

The finished product is human inspected by real-time x-ray analysis.

These interconnections can deliver DC to 10GHz, with pin-to-pin capacitance as low as 1pF, inductances as low as 2nH and connection resistance less than 10mohm.

The cost-effectiveness and rugged ability of these pins allows them to be used in the harshest conditions such as aerospace, military and automotive industries.

They are also able to perform in the most delicate devices such as medical instruments and mobile phones.
