gerber文件输出——(转_有行动,没脑袋的人)

本文详细介绍了如何在AltiumDesigner Winter09中生成Gerber文件和钻孔文件的过程,包括设置单位、选择图层及输出文件类型等关键步骤。
以Altium Designer Winter 09 为例
  1、首先如图点击 Gerber Files
     关于gerber - ∞ -    
2、 接下来在Gerber设置中选择英寸和2:5格式
关于gerber - ∞ -
 3、层菜单下点击 画线层并选择所有使用的
关于gerber - ∞ -
 4、而旁边的映射层则选择 All Off
关于gerber - ∞ -
 5、钻孔图层菜单下选择 所有已使用层对的图,右边则选择第三个
关于gerber - ∞ -
 6、光圈默认转成RS274X就行了
关于gerber - ∞ -
7、高级选项默认即可
关于gerber - ∞ -
 8、到此gerber文件已经生成,可由AD自带的CAM2000打开浏览,下图是生成的层
关于gerber - ∞ -
9、接着还要生成钻孔文件,如下选择NC Drill Files
关于gerber - ∞ -
10、选择英寸和2:5格式,并且需要选择下面其他选项中的前三项
关于gerber - ∞ -

     现在,在原始文件所在目录下就存在了gerber文件和钻孔输出文件,扩展名有:
    **.DRR   钻孔尺寸文件
    **.TXT    钻孔位置文件
    **.DRL   钻孔机驱动文件
    上面三个是钻孔输出文件;

    **.GTL     top layer,顶层走线
    **.GP1    Internal Plane1  内电层1(负片)
    **.GP2    Internal Plane2  内电层2(负片)
    **.GBL    bottom layer,底层走线 
    **.GTO   top overlay,顶层丝印
    **.GBO   bottom overlay,底层丝印
    **.GTP   Top Paste,顶层锡膏层
    **.GBP   bottom  Paste, 底层锡膏层
    **.GTS   Top Solder, 顶层阻焊层
   **.GBS   Bottom Solder, 底层阻焊层
   **.GKO   Keep Out Layer,禁止布线层
   **.GD1   点图层
  上面是各层后缀的意思。

  **.cam文件可以不用保存,将上面生成的gerber文件和钻孔文件打包压缩,送厂就行了。

and debugged. Its widespread availability allows PCB professionals to exchange image drill and route securely and efficiently. The RS-274X format is simple, compact and unequivocal. It is easy to interpret. It describes an image with very high precision. It is complete: one single file describes an image. It is portable and easy to debug by its use of printable 7-bit ASCII characters. A well-constructed RS-274X file precisely defines the PCB image data and the functions of the different image elements. Unfortunately, poorly constructed or simply erroneous RS-274X files also circulate, sometimes leading to unjustified criticism of the format itself. Errors may be due to a misunderstanding of the format. With more than 25 years experience in CAM software we at Ucamco know which areas are most often misunderstood. This revision of the RS-274X specification explains these areas more clearly. Other files are not invalid but poorly constructed. Especially troublesome are painted or stroked pads and copper planes. Poorly constructed files take longer to process, require more manual work and increase the risk of errors. This revision of the RS-274X specification recommends constructions to make RS-274X files safer and more efficient, and hence fabrication more reliable, faster and cheaper. A few words must be said about RS-274-D or Standard Gerber. This format was developed to drive NC machine tools and was used for Gerber vector plotters in the 1960s and 1970s. It is not an image description format. It is amazing that it is still used. It is like using teletype paper tape to transfer text documents. We call on industry experts and professional organizations to discourage the use of the obsolete RS-274-D format. Although other data transfer formats have come into the market, they have not displaced RS-274X. The reason is simple. More than 90% of the problems in data transfer are due not to limitations in the RS-274X format but to poor practices and, worse, the use of RS-274
