Assembly) is the process of assembling electronic components onto a printed circuit board (PCB).PCBA consists of fixing electronic components and connecting wires to a PCB by soldering technology (such as surface mount technology SMT or plug-in technology TH) to form a complete circuit system.
PCB is a pattern of conductive pathways based on a non-conductive medium used to support and connect electronic components. By mounting and connecting electronic components on a PCB, PCBA forms the structure and function of the circuit.The purpose of PCBA is to assemble different electronic components (e.g., resistors, capacitors, integrated circuits, etc.) together to realize a circuit board for a specific function.
PCBA is widely used in a variety of electronic devices and products, including TVs, cell phones, computers, home appliances, automotive electronics, and so on. It is a key step in the manufacturing process of electronic products to ensure the stability, performance and reliability of the circuit. Through PCBA, a variety of electronic components and functional modules can be assembled onto a PCB and connected to other systems or devices to complete complex circuit control and signal transmission.
