HOW TO MAKE PCB AT HOME
In this section I am going to show you how you can make your own printed circuit board at your home . For making your own DIY (Do It Yourself) PCB you will need following materials .
The price of PCB may be different as menufacturer but it will around 10$ per square foot board .check store for the pricing .
- PCB designing software
- PCB board (copper plated board )
- tonner transfer paper ( alternatively use screen printer )
- A board drilling machine ( do not cost much )
- Etching Tank ( ferric chloride solution )
PCB Copper BoardThe copper board is a thin FR4 material board plated copper in one side .The circuit is printed in this board and then the copper other than the circuit is removed by etching process which will be described below .The thickness of copper on the board is small . The copper in a PCB board is rated in ounces, and represents the thickness of 1 ounce of copper rolled out to an area of 1 square foot. For example a PCB that uses 1 oz. copper has a thickness of 1.4 mils
|weight of copper on board||thickness|
|1/2 oz.||0.7 mils|
|1 oz.||1.4 mils|
|2 oz.||2.8 mils|
