Electronic components (PCB/PCBA): the core of modern electronic products

Electronic components are the basic components of electronic devices. They realize various electronic functions through different combinations and connections. PCB (Printed Circuit Board) and PCBA (Printed Circuit Board Assembly) are important carriers of electronic components, providing mechanical support and electrical connection for electronic components.

1. PCB: The "skeleton" of electronic components
PCB is the "skeleton" of electronic components. It is made of insulating material, covered with conductive copper foil on the surface, and a specific circuit pattern is formed through etching process. The main functions of PCB include:

● Mechanical support: PCB provides a stable installation platform for electronic components to ensure that the components remain stable during the operation of the equipment.
● Electrical connection: The conductive copper foil on the PCB connects the various electronic components to form a complete circuit, realizing the transmission and processing of electronic signals.
● Heat dissipation: PCB can conduct the heat generated by electronic components to prevent components from overheating and damage.

2. PCBA: The "flesh and blood" of electronic components
PCBA is based on PCB, and various electronic components (such as resistors, capacitors, integrated circuits, etc.) are installed on PCB through welding process to form a complete circuit board assembly. PCBA is the core component of electronic products, which determines the function and performance of electronic products.

1) The relationship between electronic components, PCB and PCBA:
●Electronic components, PCB and PCBA are inseparable, and they together constitute the basis of modern electronic products.
●Electronic components are the basic units that constitute the circuit, and they determine the function and performance of the circuit.
●PCB provides mechanical support and electrical connection for electronic components, and is the carrier of electronic components.
●PCBA is a finished product that combines electronic components and PCB, and is the core component of electronic products.

2) Application of electronic components (PCB/PCBA):
