Press-fit terminals (from wire)

In recent years, demand for products that reduce solder usage has grown due to cost and environmental concerns. FINECS’ press-fit terminals meet these needs perfectly. With decades of cold forming expertise, we developed our own Cold Heading Technology for more precise and efficient manufacturing. This process produces no metal scraps and operates faster than other methods, helping customers cut costs and increase profits. We supply press-fit terminals for automotive and consumer connectors, as well as IGBT and SiC modules, tailored to your requirements.

Reference standards	□0.64mm ※ for rectangular wires or any other type, please contact us.
Material	Considering Press-fit pin applications, we recommend C5191 (phosphor bronze), because of its high springiness. In recent years – as a result of the accelerating growth of the information society – C7025 (Corson alloy) has gained attraction due to its high electrical conductivity.
Plating	Our basic procedure is: Ni sublayer + Sn (Reflow) plating. For other plating specifications, please contact us.

Applications

Replacing conventional connector terminals.

Connectors in automotive / consumer , automotive lights / sensors / actuators / motors, and more.

Power semiconductors (power modules)

IGBT modules, SiC modules, and more.
※When considering Press-fit pin usage for power semiconductors, we recommend a combination of Press-fit pins / terminals with our pin holders (sleeve pins) to secure the best connection with a substrate. Please let us know about your ideas.

Comparison with Press-fit terminals made by Press-working

Next to our Press-fit pins / terminals made from wire, we also offer Press-working to create Press-fit pins / terminals from metal sheets. Here we can provide you a very high flexibility regarding the pin shape, however please be informed that the initial costs are basically higher than those for wire processed Press-fit pins / terminals.
The latter have the advantages that no material loss occurs and initial costs are lower, but on the other hand complex shapes are difficult to handle. According to your request, we are happy to help investigate the most efficient way to create the Press-fit pins /terminals you desire. Please contact us anytime.

【About Press-fit terminals and pins】

What is Press-fit terminal?

Press-fit pins / terminals are pins that are pressed into a hole with PCB and have a structure that creates a restoring force through elastic deformation to hold the pin inside that hole.
In the past, pins have been connected by using solder, but by changing to Press-fit pins / terminals it is possible to reduce the amount of solder usage, thus also reducing production costs and environmental pollution.
