【能力素质】飞针测试输出——Probot手动输出.ppt

1、飞针测试输出 -Probot手动输出,天马行空官方博客： ；QQ:1318241189；QQ群：175569632,输入Gerber数据. 数据要求： 1、信号（Signal layer）； 2、钻孔文件（Drill files）； 3、绿油层（ Solder mask layers）；,天马行空官方博客： ；QQ:1318241189；QQ群：175569632,将钻孔层由“a01”改为“r01”,定义为钻孔，注意需要改变所有的孔层，包括盲、埋孔。（Change the Drill layer from “a01” to “r01”, it means it is DRILL. Change

2、 all drill layers, includes the blind drill or buried drill.）,检查孔层数据是否正确，如果不正确或没有孔径大小不正确，请重新读取孔层数据或手动修改孔层数据。,将顶层绿油层改为负片，即有“+”改为“-”；（Change the solder mask layer from “+” to “-”，Change the top solder mask.）,将底层绿油层改为负片，即有“+”改为“-”； （Change the solder mask layer from “+” to “-”，Change the bottom solder

3、mask.）,进入到物理层设置，（Go to “Setup Physical Layer”.）；,孔层仅仅需要是电镀孔（PTH），Only put the drill layer to the PTH；在设置物理层时，如果是埋、盲孔，必须设置将其与信号层一起设置与相应的物理层之中。（Since layer 2 is Blind drill, which connecting layer 3 disable traces.,Click in Net Point Type click box.,While pressing Ctrl key, select T and I,to highlight

4、 tps and isolated points. Exit both screens with OK.,Hit Q and Query Table will denote all testpoints by a T in the text box.,Next Step: Create Output,Note: In Net Point Type screen, C=covered point; E=endpoint; I=isolated point; L=loop point; M=midpoint; T=testpoint,Check Testpoint List,Modify Test

5、 Points?,No,Next Step: Create tp files,Yes,Create Testpoint Files,Start,Edit-enable top circuit layer (p. 45),Use Selective Mark to highlight pads of Net Point Type T and I,Edit/copy highlighted points to buffer; edit/paste to unused layer,Repeat for bottom layer,Edit newly-created tp files as neede

6、d,Drill holes 125 mls?,Save Changes,Next Step: Create Output,Yes,No,Use Selective Mark to highlight round pads with x .125,Edit/offset highlighted points in y direction,Start,Select “Write Direct” from File menu,Select “Probot” from Write Direct screen,Set “Fixture Data” to “Isolated points and tps”

7、,Select path and name for Probot Output,Specify plated drill layer and blind vias,Generally 3 alignment points chosen, single-sided,Specify top and bottom circuit layers,OK,Create Output (p. 233),Note: See “Write Direct” topic in Online Help for additional info.,Separate test point files created?,No

8、,Yes,Specify top and bottom test point files as top and bottom circuit layers,Set “Fixture Data” to “All”,Useful Hotkeys,Restore All: F7 Save All: F6 Load layers: CTRL + L Unload layers: CTRL + SHIFT + L View Extents: CTRL + SHIFT + = Order Layers: F8 Jump (to a point): J Query: Q Mark: M Unmark: CTRL + SHIFT + M Selective Mark: F9 Mark Connected: CTRL + F9 Copy to buffer: C,Cut to buffer: CTRL + DEL Paste: CTRL + INS Paste to: CTRL + SHIFT + F5 Compare Layers: = Copy Layers: F5 Control Draw: D Convert Sketched Pads: CTRL + K Set up Physical Layers: CTRL + SHIFT + P Set up Layers: CTRL +
