Abstract

A laser processing apparatus comprises a laser generator for generating laser light, a laser controller for controlling the laser generator, a positioning unit for positioning the laser light, a control method memory for storing an optimum control method corresponding to the moving distance of the positioning unit, and a position controller for controlling the position of the positioning unit by the optimum control method. Controlling the position by the optimum control method corresponding to the moving distance increases a processing speed.

Description

technical field [0001] The present invention relates to laser processing devices such as laser drilling processing equipment and laser cutting equipment, and particularly relates to a laser processing device with improved processing speed. Background technique [0002] In fields such as electronic component processing and sheet metal processing, processing such as drilling, cutting, and marking using lasers is very popular. For example, in the field of electronic parts processing, lasers are used in the drilling process of interlayer connection circuits for multilayer printed circuit boards, that is, internal via holes (IVH). In the laser processing apparatus for printed circuit boards, drilling is performed at predetermined positions on the printed circuit board by controlling the position of the laser beam or the printed circuit board. [0003] In recent years, miniaturization and weight reduction of electronic equipment are required, and in order to meet this demand, the...
