1 Multi -layer PCB production requirements for engineering data
The engineering data of the multi -layer PCB board must be fully implemented on the basis of fully realizing the requirements of the designer, which provides convenience for production to make PCB producers easier and safer to implement design requirements. Therefore, the designer's requirements for PCB are the ultimate goals of engineering data production. The production of engineering data should make full use of existing equipment resources, processing methods and processing capabilities to achieve the technical requirements proposed by design.
2 production process of multi -layer PCB engineering data
The production of engineering data is carried out on the CAD/CAM system. First of all, the design content data review of the PCB file (including the highest level, thickness, minimum line width and line distance, minimum finished pore diameter, plate shape size tolerance, pores tolerance, special requirements, etc.), and CAM system confirmed data format data Conversion; second, under the premise of ensuring the PCB design requirements, according to the production capacity and process capacity of the production line, from the perspective of processability, check and modify the GERBER files on each layer of PCB and perform a DRC inspection of the Gerber file. Finally, the PCB graphics The unit performs an automatic panel and the optimized data, drilling and milling data, flying needle detection data, and the use of copper supply and writing manufacturing instructions for the optimization of CAM.
3 The production of multi -layer PCB engineering data requires that the engineering data of multi -layer PCB board production is a guiding process file for PCB production. On the one hand, it aims to achieve design requirements, and on the other hand Essence
