Cadence Allegro光绘文件生成技巧

http://bbs.ednchina.com/BLOG_ARTICLE_250464.HTM

网上推荐的film转录方法，大概需要9层，然后每层又有4~5个小类，如果手工添加，真是要烦死人了。下面推荐两个小诀窍：
1）电路板生成的使用使用已有的电路板作为模板，这样，film就都在里面了
2）对于不能使用方法1的同志，建议这样，将下面这段拷贝到记事本里面，然后在ArtworkControl窗口里面导入，这样也比较方便（不过不保证我的配置文件能完全满足你的需要哟）

下面是配置文件
(axlfcreate "DRILL" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
   
'("MANUFACTURING/NCDRILL_LEGEND" "MANUFACTURING/NCDRILL_FIGURE"
"MANUFACTURING/NCLEGEND-1-2" "BOARD GEOMETRY/OUTLINE" "BOARD
GEOMETRY/DIMENSION" ))
(axlfcreate "PAST_BOT" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
    '("PIN/PASTEMASK_BOTTOM" "PACKAGE GEOMETRY/PASTEMASK_BOTTOM" "BOARD GEOMETRY/OUTLINE" ))
(axlfcreate "PAST_TOP" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
    '("PIN/PASTEMASK_TOP" "PACKAGE GEOMETRY/PASTEMASK_TOP" "BOARD GEOMETRY/OUTLINE" ))
(axlfcreate "SOLD_BOT" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
   
'("PIN/SOLDERMASK_BOTTOM" "PACKAGE GEOMETRY/SOLDERMASK_BOTTOM" "BOARD
GEOMETRY/OUTLINE" "BOARD GEOMETRY/SOLDERMASK_BOTTOM" ))
(axlfcreate "SOLD_TOP" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
    '("PIN/SOLDERMASK_TOP" "PACKAGE GEOMETRY/SOLDERMASK_TOP" "BOARD GEOMETRY/OUTLINE" "BOARD GEOMETRY/SOLDERMASK_TOP" ))
(axlfcreate "SILK_BOT" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
   
'("REF DES/SILKSCREEN_BOTTOM" "PACKAGE GEOMETRY/SILKSCREEN_BOTTOM"
"BOARD GEOMETRY/OUTLINE" "BOARD GEOMETRY/SILKSCREEN_BOTTOM" ))
(axlfcreate "SILK_TOP" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
    '("REF DES/SILKSCREEN_TOP" "PACKAGE GEOMETRY/SILKSCREEN_TOP" "BOARD GEOMETRY/OUTLINE" "BOARD GEOMETRY/SILKSCREEN_TOP" ))
(axlfcreate "BOTTOM" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
    '("BOARD GEOMETRY/OUTLINE" "ETCH/BOTTOM" "PIN/BOTTOM" "VIA CLASS/BOTTOM" ))
(axlfcreate "TOP" '(0 0 0 500 10000 1 0 0 0 0 0 1 1)
    '("BOARD GEOMETRY/OUTLINE" "ETCH/TOP" "PIN/TOP" "VIA CLASS/TOP" ))

配置文件结束


这样，在Avalible film窗口里面有一个Add的按钮，点击，加载我这个文件。就搞定了，还是很方便的。

如
果有好事者问这个文件怎么来的，其实也很简单。在Avalible film窗口里面在一个层上面右击鼠标，选择Select
All，然后再右击一次，选择“Save all
checked”这样会产生一个FILM_SETUP.txt的文件（和.brd文件同目录）。这个文件可以导入到其他电路板的Artwork中。


此外，这个链接是台湾人写的Gerber转录指南，还是写的不错，很有收藏价值
