Often people face problem while making a circuit on a bread board. It is a common problem that the circuit may work some time and may not work other time. Most of the time it is the connections on the bread board which creates this problem. Either are connections are not proper or loose or may get damaged while working or carrying the circuit on a bread board. Hence it is always recommended to make the circuit on a PCB once it has been tested on a bread board. But how to make a PCB at home? This article will explain the process of making a single layer PCB at home with the use of commonly available tools.
A printed circuit board has pre-designed copper tracks on a conducting sheet. The pre-defined tracks reduce the wiring thereby reducing the faults arising due to lose connections. One needs to simply place the components on the PCB and solder them.
Materials required in PCB Designing:
· Over Head Projector sheet (known as OHP sheets) or a wax paper.
· Laser Printer.
· Electric Iron.
· Steel wool.
· Two plastic trays.
· Copper board/ PCB (eg: paper phenolic, glass epoxy, FR4, FR10, etc.)
· Black permanent marker.
· Etching solution (Ferric chloride).
· Drill machine.
