The disclosure relates to a press-in pin having a tin-free and lead-free surface coating. The press-in pin also has an outer second coating. By suitable treatment after the outer second coating has been applied to the first coating, a transition layer is formed between the first coating and the outer second coating.

Press-in pin and method for producing same

An electrically conductive contact pin for press-fitting into a PCB in a Z-direction. The contact pin includes a press-fit zone with a central crosspiece area, and two wing areas adjacent to the crosspiece area, each crosspiece area having two ear areas. The crosspiece area is confined by a crosspiece rectangle and the ear regions are confined by ear rectangles. Corner points of the ear rectangles facing a center of the cross-sectional area coincide with corner points of the crosspiece rectangle. The crosspiece rectangle has a crosspiece width in an X direction of 9-29% of a starting thickness of the contact pin and a crosspiece thickness in a Y direction of 35-55% of the starting thickness. The ear rectangles have an ear width in the X-direction of 40-60% of the starting thickness and an ear thickness in the Y-direction of 15-35% of the starting thickness.
