Operation Sheet 2.2: Learning Outcome 2

This document provides instructions for mounting and soldering components onto a printed circuit board (PCB). It includes: 1. Checking the PCB against the diagram for defects before mounting components. 2. Inserting an LED according to the diagram and noting its polarity orientation. 3. Applying heat to the LED leads to solder it onto the PCB, following proper soldering technique. 4. Stripping and soldering a hook-up wire between the PCB and another connection point.

Procedure in mounting and


soldering components on
printed circuit board

1. Carefully check the readymade PCB (Printed Circuit


Board)against the diagram
and inspect for any
microscopic shorts or open
paths. Do the remedial steps,
if necessary.

What is PCB?

A printed circuit board (PCB)


mechanically supports and
electrically connects electronic
components using conductive
tracks, pads and other features
etched from copper sheets
laminated onto a non-conductive
substrate. Advanced PCB's may
contain components (as
capacitors, resistors or active

2. Insert the electronic


component LED as indicated
in the diagram.

3. Take note
the polarity orientation of
electronic component being
soldered.

3. Apply heat to the lead of


LED
by following the procedure in
how to solder on our
previous lesson

The Correct Way to Solder

4. Remove the insulation of a


#22 black stranded hook-up
wire with at least 1/8
of an inch on both ends. Insert
the uninsulated part at one end
on PCB and solder it.

5. Let your work be checked


by your teacher if your
soldering skill improved

Activity 2.2 Mounting and
