Parse And Switch The Gerber File In FPC UV Laser Processing

With the"cold"processing character, UV laser have a indispensable effect on FPC processing field. Along with the development of the high power DPSS UV laser, it's meritoriously to develop a UV laser processing system which is based on laser and moderm NC programming technology for FPC.The Gerber file is the standard file format of PCB industry. As the key step of the FPC laser processing, the figure data of the Gerber file parsing has a notable influence on the efficiency and precision of the processing.The paper adopts the Boost. Regex formula expressions library researched and developed in Microsoft research lab as strong match and analysis tool, which based on lexical and syntactic analysis. It works out a kind of Gerber file parsing and switching software with rapid match, high precision, better versatility and compatibility. This software can read the Gerber file and pick-up the figure imformation according to the FPC rapidly. It plots processing figure with the imformation and switches it to the DXF format which can recognize by any CAD software.The paper can be divided into four segments:(1) First, the FPC UV laser processing system is studied. And then introduced the framework, main task, the procedure of design and the principle of the Gerber file parsing and swithing software according to the practice.(2) Analysis the holistic configuration and data register format of the Gerber file. And introduce the parse means which adopts the Boost. Regex formula expressions library function as analysis tool based on it, insure the speed and precision.(3) Introducing the object-oriented technology to the software. Study the means of the Gerber data's reading and saving, then plots the processing figure with MFC.(4) Study the interface problem with general CAD software. Improve the expandability of the software by switching the parse data to DXF.
