Press-fit terminals are terminal pins with a structure in which the terminal is press-fitted into the through-hole of the board and is held in place by the springiness of the terminal shape. Normally, electrical connections are maintained using solder joints or SMT mounting with reflow processing, but press-fit terminals are held in place only by their restorative force, making it possible to drastically reduce manufacturing costs such as reflow equipment and electricity costs, and also to reduce environmental impact. They have been used for a long time in consumer electronics such as personal computers, and their use in automotive electronics parts has been increasing in recent years, especially in Europe and the United States, and they are expected to be used more and more worldwide in the future.
There are two types of press-fit products: press-fit products made from metal wire and press-fit products made from metal strips. The FINECS Group can provide both types. FINECS Vietnam can provide press-fit terminals mainly from press work, using 30-to60-ton presses. Currently, we recommend the needle eye shape for press-fit.

We recommend C5191 (phosphor bronze), as the "springiness" of C5191's metallic properties allows it to maximize the holding power of press-fit pins.
C7025 (Corson copper) is also suitable for press-fit pin applications, as it has a higher electrical conductivity than C5191, making it a material that is attracting attention in the development of electronic components in the age of information and communication revolution.
Ni base + Sn reflow plating is common.
Plating and surface treatment in Vietnam are available upon request.
