AT108 — How to Test Integrated Circuits — Track Signals Techniques Explained

About the Course

AT108 goes beyond basic component testing into signal-level IC diagnosis — using an oscilloscope and multimeter together, identifying I2C, SPI, and UART signals, testing clock signals, distinguishing a dead IC from a missing supply voltage, and using signal injection techniques.

What You Will Learn

• IC testing using a multimeter
• I2C, SPI, and UART signal identification
• Testing clock signals
• Identifying a dead IC vs a missing supply voltage
• Signal injection techniques

Course Highlights

• Introduces oscilloscope-based diagnosis, a genuinely advanced tool most technicians never learn to use
• Distinguishes between two commonly confused fault types (dead IC vs missing voltage)
• Builds on IT125’s component testing into true signal-level diagnostics
• A rare, high-value skill that very few South African technicians possess

Requirements

• Completion of IT125 (Testing SMD Components) recommended
• Access to a multimeter for practice recommended
• Ability to read and understand English

Who Is This Course For

Advanced technicians who want to move beyond basic voltage/resistance testing into true signal-level IC diagnosis using professional equipment.

Career Outcomes & Opportunities

• Diagnose IC faults at the signal level, not just power/voltage level
• Distinguish confidently between a dead IC and a missing supply voltage
• Build a rare, high-value diagnostic skill that very few competitors possess

Benefits Obtained

• Take-home training manual covering signal-level IC testing
• Training evaluation assessment
• Microlek Certificate of Completion in IC Signal Testing Techniques
• Access to diagnostic equipment recommendations via shop.microlek.co.za
