This week i started design my circuit and construct on PCB board. The first step is to design my PCB. in this case i used the PCB wizard software to design my circuit.

the second step is to print out the design on a transparent paper

the third step is put on the printed side of the transparent paper on the copper part of the board and iron the paper. the reason to do so is to make sure that carbon on the transparent circuit attach to the copper

the ironing process and the result. At the end, not all ink from the transparent paper will attach the copper board and surely there will be a detach on the circuit line. So to make it more perfect without further problems, i used a marker pen to highlight the circuit connection oh the copper board.


Next step is to submerge the copper board into a ferric chloride. this function to remove the all the copper on the board except the printed part.

 the fifth step is cutting the board and make holes for component by using drill to be solder on it. This

process need a high patience and great focus. Any mistake will cost me to start the process from scratch. The soldering and testing i will proceed at week 8
