1.如何在allegro中取消花焊盘(十字焊盘)
set up->design parameter ->
shape->edit global dynamic shape parameters->Thermal relief connects ->
Thru pins ,Smd pins -> full contact
2.allegro 中如何设置等长
setup -> constraints->electrical->net->routing->Min Max Propagation delays
选择要等长的net->右击->create->pin pair->选择pin
修改 prop daly 的min 和max项
3.如何设置allegro的快捷键
修改文件 $inst_dir\share\pcb\text\env 或 $inst_dir\pcbevn\env
快捷键定义如下:
alias F12 zoom out
alias ~R angle 90 (旋转90 度)
alias ~F mirror (激活镜相命令)
alias ~Z next (执行下一步命令)
alias End redisplay(刷新屏幕)
alias Del Delete(激活删除命令)
alias Home Zoom fit(全屏显示)
alias Insert Define grid(设置栅格)
alias End redisplay
alias Pgdown zoom out
alias Pgup zoom in
alias F12 custom smooth
alias Pgup slide
alias Pgdown done
alias Home hilight
alias End dehilight
alias Insert add connect
alias Del Delete
4.如何在allegro中删除有过孔或布线的层时不影响其他层
1.输出specctra的dsn文件
allegro->file->export->router->demo.dsn->run
2.产生session文件
specctra(pcb router)->file->write->session->demo.ses->ok
3.删除某一层中的布线和过孔
delete(ctrl+D)->..
4.删除allegro中的板层
setup->cross section->鼠标右键->delete
5.导入session文件
allegro->file->import->router->demo.ses->run
也可先将通过该层的过孔先替换成顶层焊盘,删除该层以后再替换回来
5.如何在Allegro中同时旋转多个零件
1.Edit->Move 在Options中Rotation的Point选User Pick
2 再右键选Term Group 按住鼠标左键不放并拉一个框选中器件 多余的可用Ctrl+鼠标左键点击去掉.
3. 选好需整体旋转的器件后 右键complete.
4. 提示你Pick orgion 鼠标左键选旋转中心.
5 下面右键选rotate 即可旋转了.
6.allegro 16.0 透明度设置
display->colour/visibility->display->OpenGL->Global transparency->transparent
7.allegro Drill hole size is equal or larger than smallest pad size.Pad will be drilled away.提示
Drill hole size is equal or larger than smallest pad size.Pad will be drilled away.
不用理睬这一提示
8.ALLEGRO 如何生成钻孔文件
Manufacture -> NC -> Drill Customization->auto generate symbols
Manufacture -> NC -> Drill Legend
Manufacture -> NC ->NC parameters->enhanced excellon format->close
Manufacture -> NC -> NC Drill->auto tool select->optimize drill head travel
set up->design parameter ->
shape->edit global dynamic shape parameters->Thermal relief connects ->
Thru pins ,Smd pins -> full contact
