Abstract

The invention provides a laser drilling device and method. The device comprises a laser, a first reflecting mirror, a second reflecting mirror, a beam shaping system, a galvanometer scanning and focusing system, a machined workpiece PCB and a machining platform; The machined workpiece PCB is arranged on the machining platform; the galvanometer scanning and focusing system is located above the machined workpiece PCB; the first reflecting mirror, the beam shaping system and the second reflecting mirror are coaxially arranged from top to bottom and are located at one side of the galvanometer scanning and focusing system; the second reflecting mirror and the galvanometer scanning and focusing system are arranged along the same horizontal axis; and the laser is arranged at one side of the first reflecting mirror along the same horizontal axis. The laser drilling device has the advantages that the influence that residual gum is easily formed due to insufficient cutting force of gauss laser to a drilling edge of the PCB is eliminated by the beam shaping system, and a high-precision and high-quality drilling effect is achieved.

Description

technical field [0001] The invention relates to the field of laser drilling, in particular to a laser drilling device and method. Background technique [0002] Printed circuit board English name: Printedcircuitboard, referred to as PCB board, is based on insulating board, cut to a certain size, and attached with conductive patterns and various functional holes on it, used to replace the substrate of the previous installation of electronic components, And realize the interconnection between electronic components. As the basis for connecting electronic components and drawing electronic conductive graphics, PCB boards have determined their absolute dominance in the electronics industry due to their stable performance, improved automation level, greatly reduced wiring, and improved assembly accuracy. [0003] In the early days, the interconnection between layers of multi-layer PCB boards and the insertion of component pins were all realized by full-through plated through holes....
