Learning Objectives
Graduates of the Electronics Equipment Repair course possess both the practical “Hands-On” skills needed in the industry and the academic knowledge required for certification. Upon successful completion of the course, participants will have the skills and experience necessary to:
- Be aware of how crucial it is to take safety measures while working with both AC and DC electrical circuits.
- When troubleshooting, an analog/digital multimeter is used to measure voltage, current, resistance, and continuity.
- Distinguish between circuits that are AC and DC.
- Take electronic components off of PCB boards and solder them on.
- Keep PCB boards away from water, vibration, and moisture.
- To clean PCBs, use the appropriate chemical sprays.
- Gain an understanding of the operation of electronic components through diagrammatic explanations.
- Determine the resistor, potentiometer, and capacitor codes.
• Locate and test the majority of the necessary electronic parts so that electronic equipment may be troubleshooted.
• Consult books on semiconductor substitution and use search engines to choose the finest replacement parts.
• Recognize the specifications included in datasheets and semiconductor part numbers.
• Examine standard equipment’s fundamental electronic schematic diagrams.
• Develop their soldering and testing abilities.
• Understand where to get electronic parts both domestically and abroad.
• Examine how the ESR and Ring Tester, two types of specialist testing equipment, work to examine various electronic components.
• Recognize the significance of grounding wires made of pure copper.
Examine a DC circuit board to see how much the operation of the circuit can be affected by a dangerous component.
• Diagnose and fix a circuit board that has components that are essentially harmful.
Recognize strategies for - Acquire a technical mentality and expertise, think critically (i.e., solve problems and develop answers), and do technical tasks with little to no supervision.
• Examine schematic diagrams for circuits.
• Recognize the reasons for power blink issues and a power supply’s fluctuating (unstable) output voltage when it is turned on.
• Recognize why, even if the output measures are appropriate, the power supply cuts off as soon as the load is attached.
• If there are no blown parts in the power supply, begin troubleshooting.
• Use a DC ammeter, light bulb, and flickering approach to isolate power supply issues and expedite the repair procedure.
• To duplicate EEPROM/Flash ROM data for troubleshooting, use a basic EEPROM/Flash ROM Programmer (Copier).
