How to Make a Circuit Board

Sometimes called PCBs or Printed Circuit Boards, a circuit board is an electrical unit that conducts elements through copper wire onto a piece of synthetic material. They're most often used in computers and other electronic devices. While you can purchase circuit boards fairly cheaply, you may want to make your own for fun or one tailored to a particular project. In what follows, you'll learn about how to make one on your own.

First, you'll need to either design a schematic for the board or learn the schematics of one that's already been designed. Check that you have all of the materials you need for the schematic and that your resistors have the correct ohm rating. Unless you're really an expert, make sure you at least have a sketch of the circuit board before you start assembly.

Take out your breadboard and lay out the circuit on top. Put your components in exactly the same place they will be on the circuit board. Once you have your breadboard set up accurately, give it some power and test it out, testing out all of the lamps and switches. If something fails to work, make sure all of the components are properly connected. If they still fail, reexamine your schematic and make sure that your plan as designed will make them work.

Once you've worked this out, construct your circuit board. Get all of your tools together and solder on all of the pieces to the board in the correct position. Make sure to carefully use all products as they take some practice getting used to. Once you're done, use compressed air and a paint brush to clean of the flux and debris, which will prevent corrosion in the board. Now the moment of truth: test out your board! With a bit of luck, it will work perfectly.
