Guide to routing a circuit on a PC Board using IsoPro Software by T-Tech
These arethe general guidelines to using Isopro T-Tech. They are intended to provide a simple set of instructions. Please refer to the T-Tech user guide for the completed and detailed instructions for using Isopro.
The first step is to import the Gerber data file into Isopro. To import the Gerber file, select File and Import from the tool bar. After the file is imported into Isopro, a default layer is developed. This layer should have been created in the Gerber file from the software that was used to generate this Gerber file, such as Agilent, Advanced Design System.
The first step is to reposition the traces to where you want the circuit to be routed with respect to the T-Tech milling table.
The next step is to isolate the traces of your design. To perform isolation, go to Tools and select Isolate.
The Isolate Layer(s) menu will appear.
Select the default layer and isolate. The traces should be isolated. The green layer around the blue traces is the new isolation layer.
The next step is to create a contour, the outer boundary of your pc board. Before you do this, create a new layer by going to the View menu and select Layer Table.
Change the layer name to Contour.
Next create tabs in the contour. This is to help the board stay in place while the board is being routed.
Select the top and bottom borders and delete them.
Go the Layers Table and select View for the Isolation and Default layers. Select lines at the bottom left corner, and create line segments for the top and bottom borders.
Select edit for the Isolation layer in the Layers Table.
Next perform a rubout for the excess areas. Go to Tools and select Rubout. Highlight the areas where you want to do the rubout.
Next you are ready to route your pc board. Turn on the T-Tech machine. The first step is to route the Isolation layer. Then run the Rubout layer. After that run the Contour layer. The very last step is to break the taps. You can do that by using a chisel.
