1. High wiring density, small size, and light weight are beneficial to the miniaturization of electronic products. 2. Can be produced automatically. PCB and PCBA can now be produced almost fully automatically, which reduces labor costs and improves production efficiency, which is beneficial to reducing product prices and popularizing the market.

3. The design can be standardized or designed as a module. When different functions are required, just replace the entire PCBA board.

The PCB serves as the foundation for the electronic device and provides the electrical connections between the components. The electronic components, such as resistors, capacitors, and integrated circuits, are mounted onto the PCB using Surface Mount Technology (SMT) and Dual In-line Package (DIP),SMT and DIP are both electronic packaging technologies used to connect electronic components to circuit boards.
