Processing PCB

Progress in making,

1) The most important thing is Printed Circuit Board. Next, put the OHP paper on the PCB.

                           

                               

                               

2) PCB added to the liquid solution ferric Chloride (FeCl3) for etching process. FeCl3 powder mixed with warm water and mix depending on how fast the circuit to be completed. Silica layer PCB soaked up entirely detached and removed and washed with clean water.

                               

                               

3) After the PCB will be included in a special liquid developer. Developers will remove the silicon oxide (carbon) and the circuit design will be seen clearly. Then PCB rinsed with clean water.

                               


4) Below the circuit was completed etching and foot hole drilled;

                               


5) Lastly, the PCB is ready to be used but before placing the component, the hole must be punch first.
