This document provides instructions for designing a printed circuit board (PCB). It defines what a PCB is, its purpose, and safety precautions for working with it. The key steps in PCB design are outlined, including preparing materials, sketching the circuit diagram on the board, etching it using ferric chloride solution, rinsing, and removing marker lines. Students will work in groups to design a PCB according to a provided schematic diagram of a full-wave center-tapped rectifier circuit with their group's acronym on it. Assessment questions and assignments are also provided.

3. DESIGN

4. Objective:
At the end of the lesson, at least 100% of the students
should be able to
a. Know the procedure of PCB designing
b. Perform the step by step procedure of PCB designing
c. Value the importance of PCB designing

5. PCB DESIGNING

6. What is PCB
Printed Circuit Board
a card made specifically for
attaching electronic components.

7. What is PCB Design
is used to design the electronic circuits. Apart
from electrically connecting, it also gives
mechanical support to the electrical components.

8. PCB serves two purpose
1. It is a place to Mount Components
2. It Provides the means of electrical
Component

9. -The PCB has two sides, the Substrate and the Copper Trace.
Copper Trace - is for connecting the
electricity between the electronic
components.
Substrate -physically holds the circuit
components and printed wires in place
and provides electrical insulation between
conductive parts.

10. SAFETY PRECAUTION:
6. If accident happens, report immediately to the
instructor.
1. Remove all jewelry before performing the activity.
2. Eating and drinking are not allowed.
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.

11. STEPS IN PCB DESIGNING:
1. Prepare the materials needed, we will be using
Permanent Marker, PCB, Ferric Chloride, Plastic
Container, Plastic Clip, Soap, Spongy Scrubber.

12. 2. Clean the PCB Board with soap using scrubber and
leave it to dry.
3. Lightly sketch circuit diagram using pencil for clear
sketch before using marker pen.
4. Carefully sketch or trace using marker pen.
.

13. 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 5-15 mins.
Etching is traditionally the process of using strong acid or
mordant to cut into the unprotected parts of a metal
surface to create a design in the metal. In modern
manufacturing, other chemicals may be used on other
types of material.

14. 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 5-15 mins.
6. Rinse the PCB with water.
7. Using thinner, remove marker lines on the PCB
board.
