Definition and Function of PCB Board and PC Board:
1. PCB Board: The full name is the Printed Circuit Board. It is a circuit board composed of an insulating substrate, conductive pattern, and pad. It is the core electronic equipment component, responsible for electrical connections and signal transmission between electronic components and providing mechanical support and protection.
2. PC Board: The full name is polycarbonate board. It is a hard plastic circuit board usually used as the shell or structure of electronic equipment. It mainly provides mechanical support and protection but does not have a circuit function.
Application Scenarios of PCB Boards and PC Boards in Circuits:
1. PCB Boards: widely used in various electronic devices, including computers, mobile phones, TVs, automotive electronics, etc. Due to its strong customizability, circuit boards of various shapes and sizes can be made according to design requirements.
2. PC Boards: usually used in electronic devices with high requirements for strength and wear resistance, such as industrial control equipment, medical equipment, military equipment, etc. Due to its high hardness and heat resistance, PC boards perform well in these fields.
The Difference Between the Functions of Inductors in PCB and PC Boards:
1. Inductors in PCB: Inductors are mainly used for circuit functions such as filtering, oscillation, and delay on PCB. They help stabilize current and voltage, reduce electromagnetic interference (EMI), and achieve specific signal-processing functions.
2. Inductors in PC boards (if any): Since PC boards are mainly used for mechanical support and protection, they usually do not contain inductors or other electronic components. If there are electronic components inside the PC board, the function of these components is mainly to protect the internal electronic equipment rather than to achieve circuit functions.
The Commonly used Inductors in PCB Circuit Boards and PC Circuit Boards are Mainly the Following:
1. Radial Inductors: This type of inductor is usually directly inserted into the circuit board through pins, and is suitable for occasions requiring higher current and power.
2. SMD Inductors: This type of inductor is small in size, suitable for surface mounting, and is often used in occasions where space needs to be saved.
3. Air-Core Inductors: This type of inductor has no magnetic core and is suitable for occasions requiring low noise and high frequency. Air-core inductors are often used in filtering and decoupling circuits.
4. Iron Core Inductors and Ferrite Inductors: These two types of inductors use iron cores and ferrite cores respectively, and are suitable for occasions requiring higher magnetic permeability and stability. Iron core inductors are often used for low-frequency filtering and power management, while ferrite inductors are used for high-frequency filtering and EMI suppression.
The Role and Application Scenarios of Inductors in Circuits Include:
Energy Storage: Inductors can store electrical energy and release it when needed, which is suitable for occasions where energy buffering is required.
Filtering: Inductors and capacitors can be used together to filter out high-frequency noise and interference signals in the circuit and improve the stability of the system.
Current Stabilization: In switching power supplies and DC-DC converters, inductors can help stabilize the output current and protect load devices.
EMI Suppression: By suppressing electromagnetic interference (EMI), other electronic devices are protected from interference.
In summary, although PC boards and PCB boards are both important components of electronic devices, they have significant differences in materials, manufacturing processes, application areas, functional characteristics, prices, etc. Therefore, when choosing a circuit board, we need to make a suitable choice based on specific application requirements and budget.
In the electronics manufacturing industry, it is very important to understand these basic differences because it can help us better understand and choose the circuit board that suits our needs. Whether it is a PC board or a PCB board, it has its unique advantages and application areas. Only when used correctly can it exert its maximum efficiency.
