Week 8(The Process of Etching and Setting Component on PCB)

The transfering process for printed circuit PCB

To transfer the printed circuit to PCB board, we made in several ways.
The usual ways, or is often done using tracing paper.
We draw circuit on tracing paper to produce the circuit for the front view, and rear view.
To draw the printed circuit on the PCB,
the circuit must be reversed prior to produce the component layout and circuit connections.
Below are the steps to move the drawing to the surface of printed circuit PCB:

a) The first is to design a printed circuit with the required shape.

b) Redraw the above printed circuit formed on tracing paper.

c) It’s sketched on the printed circuit board PCB
by using a pencil which is based on a circuit that has drawn on tracing paper that had overturned.

d) Lettering is used to redraw the circuit has been drawn with a pencil earlier in the PCB board.

e) The circuit must be determined before the process is complete the run the etching process.

The Etching Proces:


1) We put the print circuit trasparent at the UV Box.
After that, we put the UV board at the top print circuit and do the process 60s.



2) After that, we put the develop and pour and mix with the water then shake it.
This process want to make the circuit appear at UV board.

3) Thus, after done shake,
we transfer the PCB into etching tank and do the operation for 4-5 minutes.

4) Lastly,after the process and operation already done,
we use sand paper to clean the circuit board.
Finally, the circuit appear.
