PCB Layout Software
Our ExpressPCB circuit board layout program is a snap to learn and use. Laying out PCBs is easy, even for the first time user. Here are the steps:

Select the Components
Begin your layout by adding the components. Select the parts from the Component Manager dialog box. Many components (such as connectors) include Digi-key part numbers to make ordering easy.

Position the Components
Drag each component to the desired location on your board. The Snap to grid feature makes it easy to neatly align the parts.

Add the Traces
Now add each trace by clicking on the pin of a component and dragging the trace to another pin.
If you link your schematic file to the PCB, then the ExpressPCB program highlights the pins that should be wired together in blue.

See Tips for making PC boards for more help on board layout.

Edit the Layout
Making changes is simple using standard commands such as Copy, Cut and Paste. Rearrange the parts by dragging them with the mouse. Traces always stay connected to their pins, even when you move things around.

You can set the properties of items in your layout by double-clicking on them. For example, double-click on a trace to change its layer or width.

Order the PC Boards
After you complete your layout, the ExpressPCB program tells you exactly how much it costs to have the boards made. Then order them online using the Order boards via the Internet command.

Schematic Design Software
The ExpressSCH schematic design program is just as easy to use as our PCB layout software, both having the same user interface. After spending a few minutes to learn one, mastering the other takes no time at all. Here’s how simple it is to draw a schematic with ExpressSCH:

Select the Components
Begin your schematic by placing the components. Select the parts from the Component Manager dialog box. ExpressSCH includes a large library with hundreds of component symbols (ICs, resistors, capacitors…) that you can use to draw your electronic circuits.

Position the Components
Drag each component to the desired location on the page. The Snap to grid feature makes it easy to neatly align the symbols.

If all of the components do not fit on a single page, add additional sheets. All the sheets of a schematic are linked together and saved in one file.

Add the Wires
Now draw the wires to connect the parts together. Add each wire by clicking on a component’s pin, then dragging the wire to the pin it connects to.

Edit the Schematic
> Making changes to a schematic is simple using standard commands such as Copy, Cut and Paste. Rearranging the components is easy by dragging them with the mouse. Wires always stay connected to their pins, even when you move things around.

Link the Schematic and PCB
After you complete your schematic, it can be linked to your circuit board layout file.
