Title: Manufacturing device for laser beam processing device and multi-layer printed circuit board
Inventor: HIRAMATSU YASUJI
IPC: B23K26/06
Filed: 2001-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing device and a manufacturing method for a multi-layer printed circuit board capable of forming a viahole having a minute diameter in a low cost. SOLUTION: The wave length of a laser beam from a CO2 laser oscillator 60 is shortened by a tellurium crystal 94 to restrain the diffraction of the laser beam, and when the laser beam is converged, the limit value of the converge is lessened. Thereby, the spot diameter of the laser beam is made small. An aperture for a viahole is formed in an interlayer insulation resin on a printed circuit board. Hence, as a deep hole is formed, even when the output power of the laser beam is increased, the hole diameter is not widened. Therefore, an aperture for a viahole having a minute diameter can be formed.
