The Main Technical Difficulties Of Domestic UV Laser Machine
UV laser drilling machine is a kind of micro-hole processing technology based on UV laser FPC micro-hole group. Through the optimization of UV laser machine processing technology, micro-hole group processing equipment for micro-hole high-efficiency processing with small size and high surface quality is realized. The main technical difficulties involved are as follows:
(1) Quality Assurance of Micro-hole Micro-machining
There are two kinds of micro-holes: through holes and blind holes. In the FPC laser micro-mass hole processing, not only small enough pore sizes but also sufficient hole depth, good hole shape, and consistency of the porous processing must be achieved. Therefore, it is necessary to perform multi-focus mode, pulse sequence processing, and focusing. Spotlight quality optimization, precise control of laser energy, and stability of the light guide system have been extensively studied.
(2) Accurate control method in efficient punching process
The goal of domestic UV laser products is to use the high-efficiency processing of the FPC microhole group of the ultraviolet laser to achieve the drilling speed comparable to that of the ESI. This can be achieved by drilling data optimization, galvanometer mirroring, and mechanical platform synchronization. . In the specific implementation process, we need to find the shortest path optimization algorithm, and explore the synchronous control method of galvanometer mirror and platform, to ensure the quality and consistency of the porous processing while minimizing the processing time of the hole group.
