LED Lighting System Circuit Board Reverse Engineering

LED Lighting System Circuit Board Reverse Engineering

We can now create the schematic that will describe our LED Lighting System Circuit Board Reverse Engineering. This consists of placing symbols that represent the individual components in the design and connecting their individual connections, or nodes, to one another.

In the middle is the design window where we actually create our systems. You’ll notice in the left panel three windows. The upper window shows what Schematic Libraries you currently have open, and the middle window shows individual components in the library selected from that list.

If instead you see a list of files in your design database, then click the BrowseSch Tab, and set the pulldown menu to Libraries. Usually, the only open Library will be Miscellaneous. Devices. We will start by using some of its components to make a sample design.

Select CON4 from the middle window by double clicking it, and then move the pointer to the design window – you will see the outline of the component. Pressing the SPACE BAR will rotate the symbol. Pressing TAB will allow you modify the Properties of the Device.

In this case, we go to the Properties, Select the Graphical Attributes Tab, and Click Mirrored – this will reverse the symbol about the y-axis. Click once to place the component on the left side of the sheet, about half way down.

The Final Schematic is shown on Page 4 if any questions arise.

Select Place/Wire. Move the Pointer on the end point of pin 1 on the connector. A Black Circle should appear, indicating that a connection between the wire and a node on the component can be placed. Click to start the wire. Move the cursor about 6 squares, and then click again.

This will lock the wire segment and allow you to keep extending the wire in other directions. In this case, we press ESC to end the wire. Do the same for pins 2, 3 and 4.
