ExpressSCH 5.6.0

ExpressSCH is a science/CAD software which was designed as a schematic designer application, being simple 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.

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.

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.

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

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.

After you complete your schematic, it can be linked to your circuit board layout file. This image of the ExpressPCB layout program shows how it guides you in designing your board by highlighting in blue the pins that should be wired together.
