Electronic Equipment Problems Identification, Testing and Faulty Board Verification
Programme Duration: 2 Days
Programme Overview
Most modern equipment relies on electronic components and circuit board assemblies that are essential for system operation. After 2–5 years of usage, these systems commonly experience performance issues caused by faulty components on boards such as power supply boards, charger boards, main boards, controller boards and display boards.
To ensure reliable maintenance, engineers and technicians must be equipped with the knowledge and hands-on skills required for troubleshooting, identifying, testing and verifying faulty electronic boards.
In line with our vision to develop strong local expertise in electronic equipment troubleshooting and verification, this two-day training programme is designed to enhance participants’ knowledge, diagnostic capabilities and technical proficiency in board-level fault identification and verification.
Module Coverage
- Basic block diagrams and circuit functions of electronic equipment
- Identification of common problems and symptoms across equipment sections
- Safety protocols and best practices during troubleshooting and testing
- Application of digital multimeters and scope meters for measurement and verification
- Testing and verification of power supply boards and controller boards
- Testing and verification of parts assemblies, including heaters, motors and relays
- PCB repair and fault verification – DC motor controller
- Electronic component and IC testing techniques
Learning Outcomes
By the end of this training, participants will be able to:
- Illustrate the basic block diagram, operating principles and circuit functions of electronic equipment.
