Abstract:
A method of producing a contact structure having a contactor for achieving an electrical connection with a contact target, comprising the steps of:providing a substrate having a planar surface thereon;forming a plastic layer on the planar surface of the substrate;positioning a mold insert over the plastic layer, the mold insert having a shape representing at least a part of the contactor to be formed on the substrate;pressing the mold insert into the plastic layer in a high temperature environment;removing the mold insert from the plastic layer in a low temperature environment to form a plating pattern transferred from the mold insert on the plastic layer;electroplating the plating pattern on the plastic layer to form the contactor;repeating the steps of mold insert pressing and removing for other mold insert for forming a remaining portion of the contactor; andremoving one or more plastic layers from the substrate;wherein the contactor has a horizontal portion and a contact portion vertically formed on one end of the horizontal portion, and the horizontal portion produces a contact force when the contactor is pressed against the contact target.
