有关Gerber文件的疑问，应该在那里找Gerber的资料？

问题遇到的现象和发生背景

Gerber文件中 D03 闪绘光圈是什么意思？光圈描述是干嘛的？自定义光圈是干嘛的？好晕，光圈是给PCB钻孔还是印焊盘的？

用代码块功能插入代码，请勿粘贴截图

Gerber 找早期也叫光绘文件
就是一个激光束通过一个快门和一个光学透镜在感光胶片上画图。和绘图仪用笔画图很接近。
比如在坐标a,b间画一条直线，先用 D02 关闭快门，将激光头移到直线的起始坐标 a，用 D01 打开快门，在移动光头到 b 用 D2 关闭快门。这条线就画好了。
D03 是闪一下，用来画一个点
光圈也叫 D码，不同的 D 码就有不同的形状，大小。选用不同的D码能画出粗细不同的线条和点。
光圈不是给PCB钻孔的
光圈是画线条，画焊盘，画填充的。
