Procedure
A. Preparation
Teacher Activity
Students Activity
“ Good Morning Class”
“ Good Morning Sir”
“ Let us start this day by thanking God and
ask for his Guidance, Mr. Bejuco Please
lead the prayer”
“Before you take your seat kindly pick-up
the pieces of trash and arrange your
chairs.”
“Ms Secretary May I know who are the
absentees for this day?”
(Mr. Bejuco will stand in front and will lead
the prayer.)
(The Secretary of the class will stand and
tell who are the absentees for the day.)
B. Motivation
Teacher Activity
“When you hear the word designing what
comes in your mind?”
“Thank you, how do you feel when you are
given a chance to design a thing?”
“Thank you. 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. Right
class?”
“Our topic deals about steps in designing a
PCB.
C. Lesson Proper
Teacher Activity
Students Activity
(Students will raise their hands)
“ Making a thing based on what you want
to do.”
(Students will raise their hands)
“ Happy, because I can have a chance to
express what I feel”
“Yes Sir.”
Students Activity

2. “Now we are going to study The process of
PCB Designing, but before knowing the
process of designing, lets define first what a
PCB is, Anyone who has an idea?
(Pick 2 students from each group)
“Thank You, Please be noted that those
students who are participating will get extra
points for recitation.
Going back to the lesson, 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.
(Students will raise their hands)
“ PCB is a electronic tool used in every
electronic devices”

3. D. Activity
Teacher Activity
Students Activity
Safety Precaution
1. Remove all jewelry when
performing the activity.
2. Eating and Drinking is prohibited.
3. Avoid Horseplaying .
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.
Please Refer to the handouts for the Steps
in PCB Designing.
What is the First Step anyone?
(Students Raise their hands)
1. Prepare the materials Needed, we
will be using Masking tape, cutter,
Pentel Pen, PCB, Ferric Chloride
Plastic Container.
What is the second Step?
2. Cover the PCB with Masking Tape
The Third Step Class?
3. Draw up the Layout
4. Carefully trace the design using
cutter and remove the excess
Masking Tape.
th
What is the 6 step Class?
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
15-20 mins.
6. Rinse the PCB with water.
7. Remove the masking tape with the
design.
“Prepare the materials Needed”
(Student Raise their hands)
“Cover the PCB with Masking Tape”
(Student Raise their hands)
“Draw up the Layout”
(Students will draw their own Design)
th
(Students Will Follow the 4 Step)
(Students will Raise their hand)
“Subject to Etching Process.
For the etching process, Put enough
amount of ferric chloride to the container
to submerge the PCB.”
th
(Students Will Follow the 5 Step)

4. E. Generalization
Based on what you have learned in this
topic, who can now share their learnings?
“Thank You. How about the steps in PCB
Designing, anyone?”
(Students will raise their hands)
“I have learned that PCB is very important in
every device we use. It is said that PCB is
the Back bone of every Device.”
(Students will raise their hands)
“ I have learned that there are 7 steps in
PCB designing
1. Prepare the materials Needed,
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.
6. Rinse the PCB with water.
7. Remove the masking tape with the
design.
“Very Good!, It is very important to know
what is a PCB and how to do the
designing.
