PCB基板测试数据提取与图形重绘

PCB Board Data Extraction And Graphics Reduction

介绍了如何对Gerber文件导出的IPC-D-356A格式的数据文件进行解析,描述了PCB基板测试数据的转换过程,根据转换出的数据重画测试板的走线和焊盘点,重绘图形实现了PCB测试中选择基准点和错误查看等功能。

This paper describes how to parse the IPC-D-356A format data file,describes the process of flying probe test data conversion.According to the parsing data redraw the lines and pad points of the test board,according to redraw the graphics to achieve benchmark options and error check,and much more features in PCB test.
