2. PCBA stands for Printed Circuit Board Assembly, often translated as PCB Assembly. This process involves passing a PCB blank board through SMT (Surface Mount Technology) soldering, DIP (Dual In-line Package) insertion, testing, and other procedures to create a finished product, known as PCBA.
3. A PCB can transform a program that cannot independently function into a unit capable of independent operation. Excellent circuit design in PCBA can achieve optimal circuit and heat dissipation performance. PCBA generally refers to the manufacturing process, which results in a finished circuit board where the PCB is fully processed. A PCB itself is a physical printed circuit board without any components soldered onto it.

Integrated circuits (ICs) generally refer to chips that integrate functions such as the northbridge chip on motherboards or within CPUs. They are also known as integrated blocks. Printed circuit boards (PCBs), on the other hand, are the platforms where ICs are soldered and serve as their carriers.
PCBs can be found in nearly every electronic device. They provide the foundation for soldering various electronic components, facilitating electrical connections among them.
Simply put, an integrated circuit integrates a complete circuit into a chip, where any internal damage to the IC results in damage to the entire chip. In contrast, PCBs allow for the soldering and replacement of individual components as needed.
