4. A. Learning
Competencies
• LO 3.1 Apply
knowledge on lead
and lead-free
soldering
characteristics and
requirements in
mounting and
soldering process
in accordance with
OHS standards
• CG Code:
TLE_IAEPAS9-12AEP-
5. Learning Objectives:
1. Identify and explain the different
types of soldering techniques.
2. Exhibit responsibility and
accountability by adhering to safety
protocols and caring for soldering
equipment properly.
3. Practice proper soldering
techniques, such as tinning, flux
application, and joint formation, to
achieve consistent and reliable
electrical connections.
12. What is
soldering?
• Soldering is a
process in which
two or more metal
items are joined
together by
melting and
flowing a filler
metal (solder)
into the joint.
13. What is the
use of
soldering?
•It is a form of
permanent
connection
between
electronic
components
embedded in the
PCB.
14. What are the importance of
soldering?
TO MAKE SURE
THAT THE
COMPONENTS CAN
LAST FOR MORE
THAN TWO DAYS.
IT PREVENTS
OXIDATION OF THE
JOINT COMPONENTS
FOR THE LONG
PERIOD OF TIME.
15. What are
the three
basic
principles
of
soldering?
• Clean the soldering iron.
• Clean the electric components.
• Clean the Printed Circuit
Board (PCB)
Cleaning.
•Connecting parts must be heated
to a proper temperature evenly
Heating.
•A proper amount of solder must
be supplied to a properly heated
spot.
3. Soldering
16. What are the two kinds of
soldering?
Automatic soldering is an automated system
that performs the application of solder
paste, pre-heating, soldering, cooling,
drying, and hardening. (Ex. Robot soldering)
Manual soldering – a method of soldering
performed by human.
17. Health and Safety Precautions
Prepare the
workplace
clean,
orderly and
ready for the
activity
Remove all
jewelry/acces
sories
before
performing
the activity
Always wear
your personal
protective
equipment
(PPE)
No eating or
drinking in
