Kontaktsonde und deren Herstellungsverfahren

摘要

A contact probe is fabricated by a method including a lithography step and a plating step. The contact probe includes a plunger unit (1) to form contact with a circuit to be tested, a spring unit (2), and a lead wire connection unit (3), all formed integrally so as to have a three dimensional configuration with uniform thickness with respect to a predetermined plane configuration in a thickness direction perpendicular to the predetermined plane configuration. Preferably, a guide unit (6) parallel to the spring unit (2) is also formed integrally. Further preferably, the contact probe is formed integrally also including a stopper (7) for each unitary configuration of the spring unit (2) constituted by a leaf spring.
