MANUFACTURE OF PROBE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a probe device that enables automation and reduction in manufacturing cost. SOLUTION: A line discharge polishing operation 10 uses the principle of microdischarge machining. A line discharge device machines fine electrodes in a probe. An electrochemical discharge machining operation 20 uses nonconductive material machining techniques and forms a current path in the portion of contact between a printed wiring board in an electrolytic solution and the probe machined and polished. A line discharge polishing operation 30 is performed to enhance the dimensional accuracy of the probe. A joining operation 40 solders the probe to the printed wiring board, and a cutting operation 50 cuts the probe attached thereto. These operations are repeated and a flattening operation 70 is performed to complete a probe device.
