| Wizards | Printed Circuit Board Wizard | OK". You should see the "Documents" tab in the right frame. Then the "Documents" folder in the left frame

(1) Click on the "Explorer" tab in the left frame, Layout (assuming you already have a schematic): When you're doing a new board "from scratch", To try to import those design files into Protel If you already have a board designed using some other software, The other change I made was to make the "Unspecified Port" row and column all error (red), as I don't want to have ANY port unspecified. This will require you to put a "No ERC" marker on any unconnected pins, but that seems like a good idea, anyway. ``The main change to the ERC matrix that I'd suggest over the default is to set the "Unconnected" row and column to either warning (yellow) instead of No Report (green). Row and column is identical to ``output pin''. ``Unconnected'' row and column is warnings and errors.įor an explaination of why the input port ``Tools | ERC | Rule Matrix'' so that the entire (or manually prototype it on solderless breadboards), then If you don't have a Protel document that someone has already set up properly,ĭraw a schematic #start_schematic, simulate it Find the parts listed in your BOM, buy them, and send them to your assembly house.

The assembly house makes stencils from the ".GTP" (if you have SMT components on top) and ".GBP" (if you have SMT components on bottom) files while the board house is etching the board.

Email the ".zip" file to your favorite board house, *and* another copy to your favorite assembly house.

You right-click on the folder they are in and choose "Add to CAM.zip". You copy a "readme.txt" file into that folder.

You exit Protel, find the new Gerbers.

All the Gerbers, the Drill Drawing, the Drill Guide, the BOM, and other files will be generated and placed in "CAM for." folder inside the ".ddb" file and copied to a (hopefully appropriate) direction elsewhere on your hard drive. Find the file of type ".cam", click it, and then hit F9.

Hit the "Explorer" tab on the far left.

All too often your "fixes" cause other problems.

Hit "Tools | Design Rule Check | Run DRC" to run a design rules check.

You increment the revision number on the silkscreen on the board.

You find the ".ddb" file for Board Y, double-click on it, then find the ".PCB" file.

Move them closer together on the next revision, OK ?". The holes are too far apart for Component X on Board Y. If you have a Protel document that someone has already set up properly, it's easy to make minor changes to the PWB. The details are Protel-oriented, since that's what I know, Here's the basic sequence of steps you go through when you work on a PWB (printed wiring board) using CAD design software.
