1. A simple method to facilitate testing and repair of small SMD components involves binding sewing needles to multimeter test pens with thin copper wire, reducing short circuit risks and enabling direct contact with coated pins. 2. In circuit board maintenance, detecting short circuits in common power supplies is crucial. “Ground hoeing” may work for boards with fewer components, but for denser boards, a method involving an adjustable power supply is more efficient. Gradually increasing the current while monitoring heat can help pinpoint faulty components.
