Laser drilling machine performance detection method

Abstract

The invention discloses a laser drilling machine performance detection method. The method comprises the following steps that S1, a laser drilling machine punches a hole in an acrylic plate, and the depth direction of the hole extends in the thickness direction of the acrylic plate; S2, the acrylic plate is sectioned in the radial direction of the hole to form a sectioning state of the hole; S3, the diameter of the top of the hole is measured; the depth of the hole is measured; the offset of the depth line of the hole is measured; and S4, the laser drilling machine is detected. According to the method, the performance of the laser drilling machine is reflected in an acrylic plate punching mode, and the method is a visual method for detecting the performance of the laser drilling machine. According to the method, the energy difference and the light path deviation between machine tables are verified through the method of punching the acrylic plates on the laser drilling machine regularly, potential unstable factors of the machine tables are found in time and solved, the stability and the production yield of the equipment are greatly improved, and the quality problem caused by equipment abnormity does not occur any more. The method is simple and effective.

Description

technical field [0001] The invention relates to a method for detecting the performance of a laser drilling machine. Background technique [0002] HDI circuit board is the English abbreviation of High density interconnection, which has become the fastest growing field in the printed circuit board industry. And an important process in the HDI process "CO 2 "Laser drilling", its purpose is to drill holes with small apertures to realize the interconnection between layers. In the industry, CO 2 The equipment used in laser drilling is mainly a laser drill. [0003] The entire optical system of the laser drilling machine is relatively complicated. From excitation to application to drilling processing, the infrared laser needs to pass through dozens of lenses. Although the machine has its own laser energy and accuracy inspection function, the energy and accuracy detectors will There is a certain error, and other hardware such as the laser head, wave splitter, oscillator, etc. The...

[0003] The entire optical system of the laser drilling machine is relatively complicated. From excitation to application to drilling processing, the infrared laser needs to pass through dozens of lenses. Although the machine has its own laser energy and accuracy inspection function, the energy and accuracy detectors will There are certain errors, as well as the different status of other hardware such as laser head, wave splitter, oscillator, etc., resulting in the monitoring of daily equipment is not enough to fully monitor the differences between machines, so For laser drilling machines, the stability control of equipment has always been a difficult point
