    Abstract: A board-to-board connector and an arrangement with two circuit boards. A body of the connector is provided with one or more electrically conductive contacts. Such a contact includes a soldering surface for the contact to be attached to a conductive pattern of a first circuit board. The contact further includes a contact surface to be arranged in contact with the conductive pattern of a second circuit board. The second circuit board is arranged at a distance from the first circuit board and substantially parallel therewith. The contact still further includes a spring part arranged between the soldering surface and the contact surface. The contact surface is in immediate contact with a part of the conductive pattern on the surface of the second circuit board and the spring part allows resilience between the soldering surface and the contact surface in a perpendicular direction with respect to a plane of the soldering surface.
