When you hear the word designing what comes in your mind?
“Making a thing based on what you want to do.” Yeah
How do you feel when you are given a chance to design a thing?
For me it really feels good if you are given a chance to design, though you
have the freedom to make or design what you want there is always a step to be
followed in order to make the right design.
Printed Circuit Board Designing
Learning Objectives:
- Discuss the procedure of PCB designing clearly.
- Perform the step by step procedure of PCB designing.
- Value the importance of PCB designing.
Materials:
Pentel Pen or a marker
Ferric Chloride
PCB
Masking Tape
Cutter
Plastic Container
Our topic deals about steps in designing a PCB. Now we are going to study The process of PCB designing, but before knowing the process of designing, let’s define first what a PCB is,
“PCB is an electronic tool used in every electronic devices.”
The Printed Circuit Board or PCB is a card made specifically for attaching electronic components.
PCB serves two purpose:
1. It is a place to mount components.
2. It provides the means of electrical component.
The PCB has two sides, the Substrate and the Copper Trace.
The Substrate physically holds the circuit components and printed wires in place and provides electrical insulation between conductive parts.
While the Copper Trace is for connecting the electricity between the electronic components.
PROCEDURES:
First you need to follow the
safety precautions;
1. Remove
all jewelry when performing the activity.
2. Eating
and drinking is prohibited.
3. Avoid
horse playing.
4. Be
familiar with the tools and chemical to be used.
5. Do
not perform the activity unless the instructor told you to do so.
6. If
accident happens, report immediately to the instructor.
Steps in PCB Designing:
1. Prepare the materials needed, we will be using masking tape, cutter,
pentel pen, PCB, ferric chloride, plastic container.
2. Cover the PCB with masking tape
3. Draw up the layout.
4. Carefully
trace the design using cutter and remove the excess masking tape.
5. Subject
to Etching Process.
For the etching process, put enough
amount of ferric chloride to the container to submerge the PCB. Usually the etching process takes 20-30 minutes.
6. Rinse
the PCB with water.
7. Remove the masking tape with the design.
8. Done.
