PCB making is an
interesting art acquired by an electrical and electronics Engineer. In March
2012, Pratik and Sourabh (who has been admitted in D.BATU University, Lonere and
Raigad) prepared two mini project circuits as their Workshop submission. Here,
we will see how to make simple PCB circuit?
Insteead f wasting more time on praising their circuits, lets go the procedure:
1. To make simple PCB board, you
should have a working circuit with you.
2. Place its components on
Bred-board and check whether your circuit is working or not.
(If you are sure about your circuit that it is
working then you can neglect this step but it is highly recommended to once
check your circuit with the help of bred-board)
3. It is usual practice to use
General PCB for mini projects. Go to market and buy a General PCB board. They
are available in two different sizes. Small size costs for Rs. 10-15/- whereas
medium size costs for Rs 50/-. Select best suitable size PCB with respect to
your project size and no. of components involved in it.
4. Mark a path of your circuit on
both sides of PCB using permanent marker. This will help you to prevent
misplacing of components.
5. Place circuit components on
their respected place and cut their legs by cutter. (Make sure that you have
placed all the components with correct direction as their might occur a problem
with anode and cathode sides of unidirectional devices like LED’s, Diodes, etc)
6. Now, its time to move on with
Solder gun. We highly recommend to go for spot soldering. Use single stranded
connecting wires for connection of any two points. Do not place Solder gun on
components legs continuously for more than 3 seconds as it may cause damage to
it.
7. After completing soldering
process, try working of your circuit. It has been observed that there exists
open circuit due to dry soldering. Troubleshoot it and go on trying till your
circuit doesn’t work.
Some extra points;
I) If you wish to check
functionality of any single device, it is worth that you remove its at least
one leg from circuit.
I) While using IC, always use IC
holder. It will increase flexibility of circuit.
