23 Chengdu instrument customization undertaking_ Discussion on automatic wiring method of PCB in Protel DXP

SO SCM development guide 23

Requirements are not high, but simple , Why bother to think about it , And it's hard for people to win , Automatic wiring and timely access . This article is introduced in Protel DXP in PCB The method of automatic wiring in drawings .

Automatic wiring is suitable for circuit boards with low requirements . Automatic wiring is simple , Click the button , The system starts wiring itself , But good automatic wiring also needs to do a few things ：

-> Set the wiring rules ;

-> Set the no wiring area ;

-> Click auto wiring .

Here is a diagram ：

1、 Set routing rules

The wiring rules have been detailed above , Here is just a brief mention .

Click on Design/rules, Enter the rule editor . There are several key parameters ：

-> Line spacing ;

-> Line width ;

-> Corner, etc .

2、 Set the forbidden wiring layer

Setting the forbidden wiring layer was also mentioned earlier , The forbidden wiring layer is used to set the boundary of wiring , stay keep-out layer Operations in layers .

3、 Automatic wiring

Click... On the menu bar above Auto route/all, The system can start automatic wiring .

However, the wiring may fail , Look for the messages Prompt in the prompt box , If failed Not for 0 There are failures . If there are failures , Sure un-route( menu bar tools/un-route) Then adjust the component layout and rewire , You can also switch the failed connection to manual wiring connection .

The effect of automatic wiring is shown in the figure below ：

Then delete other auxiliary graphics , It completes the final PCB Drawing .

4、 Summary

When it's done , Put this file （ The suffix is .PCBDOC） Send it to the circuit board manufacturer , Can process circuit board .

Just to add , As mentioned above, it is on the forbidden wiring layer （keep-out layer） The boundary of the circuit board drawn in is actually not standardized , The boundary of the circuit board should be drawn in the mechanical layer . however , There is no big problem in drawing the boundary of the circuit board on the forbidden wiring layer , In fact, general manufacturers also understand .

This circuit board design series ends , But the wonderful is not over , Next, I will talk about the programming of MCU . Provide single chip microcomputer 、PLC、 Circuit board 、 controller 、 Instruments and Apparatuses 、 Software 、APP、 Electromechanical equipment or system 、 Industrial control 、 Automatic control system 、 Control system development and design customization , Contact figure 2 website .
