ABSTRACT:
An apparatus for producing a contact/connection member for electronic parts has a base material supply unit for continuously supplying a flexible belt-shaped base material, a wire material supply unit for continuously supplying a precious metal wire material, a welding unit for diffusion bonding the wire material to a surface of the base material by applying electricity to a mother rotation electrode and a variable rotation roller electrode while the wire material is pressed against the surface of the base material between the electrodes at a welding location, and a take-up unit for the bonded contact/connection member. A cooling unit may be provided for the welding unit. The apparatus produces a contact/connection member having a base material thickness of between 0.03 to 3.0 mm and a width of 3.0 to 300 mm in which the base material may be any of a variety of materials, including phosphor bronze, German silver, copper or other materials, and the wire member is a linear, stripe-shaped, shell-shaped, or hoop-shaped precious metal material such as gold, platinum, silver, or other precious metals or alloys.
