1.Print the diagram required , Print it out on a glossy paper, such as Sticker paper or magazine paper.
2. Stick the circuit diagram on the paper with the circuit board (the diagram should be facing the copper part of the circuit board).
3.Use cutter cut removes any unnecessary copper from the board leaving only wiring of the final circuit.
3.Slowing start taking off the paper and soon all of the paper should come off. If certain areas seem particularly difficult to peel off, you can try soaking a bit more. If everything went well, you will have a copper board with your PCB pads and signal lines traced out in black toner.
Etch the board using one of the methods below. This process removes any unnecessary copper from the board leaving only wiring of the final circuit.
Prepare the acid etchant. For example, some crystallized acids require being dissolved in hot water
Submerge the board in the acid.
Make sure to stir every 15-20 minutes.
Take the board out and wash it when all unnecessary copper is etched away from the board.
Drill mount points. Drilling machines used for that are usually custom machines designed specifically for this purpose. However, with some adjustments a usual drilling machine will do the job at home.
Mount and solder the electronic components on board.
