Across
- 2. A chemical cleaning agent used to remove oxidation and facilitate the flow of solder.
- 4. The electrical potential difference between two points; the "pressure" that pushes current.
- 5. A hand-held tool with a heated metal tip, used to melt solder and join electronic components.
- 7. A small tool used for picking and placing tiny surface-mount components (SMDs).
- 9. A fusible metal alloy (often tin and lead) melted to create a permanent bond between metal workpieces.
- 12. A sudden flow of electricity between two objects that can damage sensitive electronic components; often prevented with a wrist strap.
- 13. A semiconductor device used to amplify or switch electronic signals and electrical power.
- 15. An instrument used to observe and measure the waveform of electronic signals, showing voltage over time.
- 16. A complete and closed path through which electric current can flow.
- 17. A common return path for electric current, often considered to be at zero voltage potential.
- 20. A semiconductor device with two terminals, allowing current to flow easily in one direction but not the other.
- 21. An electrical test to determine if a path is complete (closed) or broken (open), often signaled by a beep.
- 22. A basic discrete element or device that is part of an electronic circuit.
- 25. A device with a fan and filter used to remove harmful smoke and particles created during soldering.
- 26. A reusable platform for prototyping circuits without soldering, using plug-in connections.
- 27. A material, such as plastic, that resists the flow of electric current.
Down
- 1. An electronic measuring instrument that combines several measurement functions (voltage, current, resistance) in one unit.
- 3. A tool designed to remove the insulating covering from electric wires without damaging the conductor inside.
- 4. A clamping tool used to hold a circuit board or component steady, leaving both hands free to work.
- 6. A holder for a hot soldering iron, often including a sponge for cleaning the tip.
- 8. A hand tool used for gripping, bending, or cutting component leads and wires.
- 10. A passive two-terminal electrical component that implements electrical resistance as a circuit element.
- 11. A material, such as copper, that allows electricity to flow through it easily.
- 14. A diagram that shows the electrical connections and functions of a circuit using standardized symbols.
- 16. A passive component that stores electrical energy in an electric field, measured in farads.
- 18. An optical lens that provides magnification to help see fine details on small circuit boards.
- 19. A tool used to remove excess or unwanted solder from a joint, often for component removal.
- 23. The rigid flat board that mechanically supports and electrically connects electronic components using conductive tracks.
- 24. The shape and form of a signal, such as a sine wave or square wave, as seen on an oscilloscope.
- 28. A tube that shrinks in diameter when heated, used to insulate wires and protect connections.
