I was hoping to see a solderless technique for joining through-hole components to a PCB, but that is just as nice to see. > Class A provides improved vibration characteristics, and is the required wrap style for spaceflight hardware applications. > Class B terminations, characterized by the absence of insulated turns, are prohibited. So one or two insulated turns make a notable difference in vibrations. Pretty neat.
