Etching PCB 1 of 2

These are the steps taken in order to produce circuit board.

1) Designing the circuit schematics and layout ...











2) Print it on paper for checking purposes ......











3) Print them onto transparency using a Laser Jet printer.....











4) Transferring layout onto PCB board.... make sure that the copper mounted surface is smooth and is thoroughly cleaned ....









5) This is the old conventional method of transferring the layout onto the copper board through heat transfer process....time consuming.... approximately 3 to 5 minutes .....

6a) Dip the board into Ferric Chloride acid to remove the copper layer. Shake the container momentarily for faster results.....









6b) Notice that the copper layer has been wash/wipe off....











7) After a few minutes of acid bath process... the expose copper layer is totally removed.











8) Wash the board with water to clean the remaining acid...











9) Clean the printed ink with alcohol or spirit...
