A printed circuit board (PCB) can have various layer structures and components, including pads, vias, and traces, each serving specific functions, with common types being single-layer, double-layer, and multi-layer boards, which differ in their manufacturing and functionality.
The PCBA process involves manual and automated assembly methods. Manual assembly requires careful handling of odd-form components during placement and soldering, while automated assembly uses specialized equipment for efficient placement and soldering of various component types, aiming to streamline production despite potential bottlenecks

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.
