Multimeters measure voltage by comparing an unknown voltage to a known reference voltage, and measure current by passing it through a known resistance.

Advantages: Easy to use, no soldering required. Disadvantages: Limited current carrying capacity, can be less reliable.

As the soldering types progress from hand soldering to wave soldering to reflow soldering, temperatures and joint strength increase.
