About the program

What is the Professional Diploma in Electronic Circuit Diagnosis and Repair?

This professional diploma prepares you to diagnose and repair electronic boards at component level, the skill that keeps onboard, industrial and consumer equipment running instead of being replaced. You will learn to apply Ohm's and Kirchhoff's laws to diagnosis, read schematics and datasheets, use multimeters, oscilloscopes, signal generators, ESR meters, curve tracers and thermal cameras, isolate faults with top-down, bottom-up and block-division strategies, repair linear and switch-mode power supplies, amplifiers, motor drivers and microcontroller systems, recover firmware, and rework THT, SMD, QFP and BGA components and damaged PCB tracks.

What sets this professional diploma apart: a systematic fault-finding methodology based on decision trees and diagnostic flowcharts; advanced instrumentation, from in-circuit measurements to thermal imaging and voltage injection; in-depth coverage of switch-mode power supplies, one of the most common sources of failure; a balanced view of analog, power and digital electronics, including communication buses such as I2C, SPI, UART and CAN; professional soldering and rework techniques, from SMD to an introduction to BGA reballing; and a final project in which you solve and document a complex board-level fault.
