Express PCB is a very easy to use Windows application for laying out printed circuit boards. One will find a rectangular box on Express PCB screen with yellow colored border. This rectangular can be expanded using only three corner points not the first one as it is fixed as the reference. A beginner can create his or her circuit diagram for PCB in this rectangle only. See the below image, corners that can be adjusted are marked.
Express PCB contains two bars- one on its top called top menu bar and other on its side called side toolbar. Both are used together to make a complete circuit diagram. But, the important toolbar is the side toolbar. See the list of components in the below image.
(1) Select button- It is selected to select a component and to get back your mouse cursor function.
(2) Zoom view- It is clear from its name but slightly different from other zooming features. As, it zoom only the selected area. You select an area which you want to see clearly and then, click on this zoom option.
(3) Place a Pad- Pad is the point which is used to connect the different component through tracing or wiring. You can see the pad around every component in Express PCB, when selected and inserted.
(4) Place a component- This option is also available in the Top menu toolbar. Whenever it is selected, it provides the option in the upper menu toolbar to select and insert a component from drop-down selection and you can also rotate you component in different direction with 90 degree angle.
(5) Place a Trace- It is used a wire connection between the pads of the components which has to be connected
(6) Insert a corner- Select this to insert a dotted marked point anywhere in the trace connected between the components.
(7) Disconnect a trace- Select this tool and then, click on the trace which you want to cut. It does not delete the trace instead it only cut the trace from its corner so that you can move the trace from that point.
(8) Place a Text- It is explained from its name. You can place any text anywhere using this tool. When you click on this option, a writing option will appear on top menu bar where you have to write a text before inserting it into the circuit diagram.
(9) Place a rectangle- Simply select this tool and place a rectangle.
(10) Place a circle- Select this tool and place a hollow circle.
(11) Place ground plane- Select and place a filled shape anywhere in the circuit diagram.
(12) Inset an edge segment
(13) Pad info- Select this tool and then, click on any pad of a component to know the information about it.
Other tools are related to visual the view of final circuit diagram that will be implemented on copper layered PCB. You can select different copper layer to make traces according to the implementation of
circuit diagram on PCB.
