Press-fit pins / terminals (from wire)
This product is manufactured and sold by FINECS.
About Press-fit pins / terminals
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.

Comparison with Press-fit pins / 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.

Available sizes
□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.
Press-fit pin / terminal shapes
We highly recommend the needle-eye type, but if you are interested in different shapes, please let us know.※ Regarding the investigation of shape-related patents, we kindly ask our customers to do this beforehand.
Plating
Our basic procedure is: Ni sublayer + Sn (Reflow) plating. For other plating specifications, please contact us.Applications
① Replacing conventional connector terminals.Connectors in automotive / consumer , automotive lights / sensors / actuators / motors, and more.
② 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.

Characteristics of FINECS’Press-fit pins / terminals
Our Press-fit pins are all manufactured by FINECS original processing machines. In recent years, due to the desire of reducing manufacturing costs and environmental pollution, the need for products which can reduce the amount of solder usage has highly increased. Our Press-fit pins / terminals perfectly fit both requirements. At FINECS we own decades-long experience of cold deformation processes, and have further developed our very own Cold Heading Technology to offer you even more accurate mechanical operation, thus more precise manufacturing of Press-fit pins / terminals than ever before.Our Cold Heading Technology does not leave metal scraps, and its processing speed can be increased to a higher level compared to other processing methods, which enables customers to reduce costs and generate more profits. If Consumer or automotive connectors, IGBT or SiC modules, at FINECS we manufacture Press-fit pins / terminals according to your request, so please rely on us.
