1. What is PCB?
Multilayer Circuit Board
PCB, or Printed Circuit Board, which can be referred to in Chinese as circuit board, circuit board, printed circuit board, etc., is a key component in electronics manufacturing.PCB is designed as a flat plate, usually made of insulating material, on which conductive lines and connection points are laid. The layout of these conductive lines and connection points is designed according to the needs of the electronic components.They support the electronic components and enable connections between them.
2. What does PCBA mean?
Circuit Board Soldering
PCBA, i.e. Printed Circuit Board Assembly, is usually also referred to as PCB Assembly in foreign countries.PCBA is the next step of PCB, which involves putting a blank PCB board through a series of processes, including SMT placement, DIP insertion, and testing, etc., to end up with a finished product. This finished product is no longer a blank board, but a circuit board with certain functions and various electronic components installed on it, such as resistors, capacitors, chips, and so on. In fact, the core part of almost all electronic products is composed of PCBA.
3. The difference between PCBA and PCB?
The most crucial point to understand the difference between PCBA and PCB is their status and function:
PCB is an empty board with no electronic components installed on the surface, only conductive lines and connection points.
PCBA is processed and assembled on the blank PCB, installed a variety of electronic components, forming a circuit board with a specific function.
The PCB provides the basis for the placement of electronic components, while the PCBA assembles these components together so that they can work together to realize electric.
