o been working for some time

o Already have completed training in this area.

INTRODUCTION

This module contains information and suggested learning activities on Computer System Servicing NC II. It includes the following competencies: plan and prepare for termination/ connections of electrical wiring/electronic circuits, terminate/connect electrical wiring/electronic circuits, and test termination/connections of electrical wiring/electronic circuits.

Side Cutter Pliers - used for cutting or trimming of connecting wires or terminal leads in the circuit board
Long nose Pliers – used for holding, bending and stretching the lead of electronics component or connecting wire.

Soldering Pencil – used to join two or more metal conductors with the support of soldering lead melted around it.

OHS – Occupational Health and Safety

Assessment Criteria:

1. Materials are checked according to specifications and task.

INFORMATION SHEET 1.1

Use of Tools

Without the knowledge and aid of the multitester and other sophisticated equipment such as regulated power supply, signal generator and oscilloscope, troubleshooting is impossible. Here are the following basic tools and equipments needed for the repair of electronics devices and appliances:
