Electrostatic discharge — the invisible, silent killer of components: what ESD is and why a discharge you can't feel destroys sensitive parts, the damage it does, and the grounding, materials, and habits that prevent it at the bench.

The core hand tools of electronics repair and how to use them well — screwdrivers and driver sets, spudgers and pry tools, tweezers and cutters, and the rest of the kit that opens, handles, and works on devices without damaging them.

The heat sources at the heart of repair — choosing, understanding, and setting up soldering irons and stations, temperature-controlled versus fixed, hot-air rework stations, and the other heat tools, so you can make clean joints and rework parts reliably and safely.

The repairer's most-used instrument, mastered — the multimeter's anatomy and controls, measuring voltage, resistance, continuity, and current safely and correctly, plus how to choose a meter and read what it tells you.

The instrument that shows what a multimeter can't — the oscilloscope, mastered: seeing a signal's voltage over time as a waveform, its anatomy and controls, probes, triggering and timebase, and reading the shape, timing, and quality of the signals a repair depends on.

Beyond the multimeter and oscilloscope — the specialized instruments that answer questions the everyday tools can't: logic analyzers for digital buses, thermal cameras for hotspots, ESR and LCR meters for components, bench power supplies, and protocol analyzers. When to reach for each, and how to use it in repair.

Seeing the work — because modern surface-mount components are too small to inspect, place, or solder reliably by the naked eye. Why magnification is a prerequisite for SMD repair, and the options for getting it: loupe magnifiers, stereo microscopes, digital and USB microscopes, and how to set them up with the right working distance.

• 9.3Stereo Microscopes — Selection and Use24 min
• 9.4Digital Microscopes and USB Cameras22 min

The consumables that repair runs on — the materials you feed the tools. Solder alloys and forms, flux and its cleaners, desoldering wick, thermal paste and adhesives, conformal coating, and wire: what each is, how to choose it, and how to handle it safely, from the metal that makes the joint to the chemicals that clean and protect the board.
