Lab Tools & Soldering
Breadboards are for learning; soldered joints and measurements are how you know a prototype is real. This subject is using a multimeter, and where available a logic analyzer or oscilloscope, plus making a sound through-hole solder joint and knowing when to desolder. Ventilation, ESD awareness, and not guessing voltages by touch are part of the craft.
Starting Points
- Electronics & circuit prototyping
- Instrument manuals for the lab multimeter, soldering iron, and (if available) scope / Saleae-style analyzer.
- Weller / Hakko through-hole soldering guides from your lab.
Key Points
- You measure voltage, continuity, and (where safe) current with a multimeter and interpret the reading.
- You capture a digital signal with a logic analyzer or a simple waveform with a scope and relate it to the firmware.
- You make a through-hole solder joint that is shiny, concave, and mechanically sound, and you inspect it.
- You desolder a mistake without lifting the pad, using pump or wick.
- You work with basic lab safety: ventilation, iron stand, ESD where required, and you never probe a live mains circuit.
