Electronic Components: Master SMD Testing with Multimeter, From Capacitor to IC | Electronics Repair

Tavsif:

Learn how to test SMD electronic components like a professional using just a multimeter. You’ll learn how to safely and correctly check ceramic capacitors, MOSFETs, voltage regulators such as the LD1117, capacitors, transistors, diodes, ICs, fuses, switches, and zener diodes. This video simplifies electronics repair and testing techniques so even beginners can understand how to diagnose faulty SMD parts on any laptop or circuit board. You’ll see real‑life examples, polarity tests, and voltage checks that help you find bad components instantly. Perfect for electronics technicians, students, and engineers, this short teaches how SMD parts behave versus traditional THT components, and why understanding their behavior is key to fast, effective repair. It covers how to test ceramic capacitors, zener diodes, and transistors, how to test ICs and voltage regulators safely, how to use the multimeter in diode mode and resistance mode for quick checks, how to identify shorts and open circuits on SMD boards, and how to troubleshoot SMD issues quickly on laptops and power circuits.
