PCSPCB for you to talk about the origin and significance of PCB board color? The role and characteristics of PCB board color. In the field of electronic manufacturing, whether it is the product on the market or the equipment in the production workshop, we will find a variety of PCB boards, their colors are varied, from common green to rare red, blue, black, etc., which is dazzling. So, what is the use of these different colors of PCB boards? What secrets are hidden behind them?
The origin and significance of PCB board color
First of all, let's understand the origin of PCB board color. The color of the PCB board is mainly determined by the solder resistance layer on its substrate, and the role of the solder resistance layer is to prevent the free flow of solder during welding to avoid short circuit. The color of the solder mask can be achieved by adding different colors to form the colorful PCB board we see.
The role of PCB board color
1. Easy production and maintenance: Different colors of PCB boards can help workers quickly distinguish between different product batches, production processes or special requirements. In the production process, the color difference helps to achieve pipelining and process control; In the maintenance process, the color can be used as a reference for fault location to help maintenance personnel quickly find the problem.
2. Improve the beauty: PCB board as a core component of electronic products, its beauty has also received more and more attention. Colorful PCB boards can meet the individual needs of consumers and add a unique beauty to electronic products.
3. Functional distinction: In some special application scenarios, the color of the PCB board can also be used as a functional distinction. For example, in high-density electronic devices, PCB boards of different colors can distinguish different signal transmission paths, improving the overall performance of the device.
4. Reflect the quality of the PCB board: the color of the PCB board also reflects its quality to a certain extent. High-quality PCB boards are usually uniform in color, full and not easy to fade, while poor quality PCB boards may appear uneven color, color spots or fading, affecting the performance and reliability of the board.
5. Adapt to special environments: In some special environments, the color of the PCB board needs to be adjusted. For example, in high temperature, high humidity or corrosive environments, choosing a color with better weather resistance and corrosion resistance can extend the service life of the PCB board.
Common PCB board color and its characteristics
1. Green PCB board: the most common, with good visibility and recognition, mature production process, low cost, widely used in all kinds of electronic products.
2. Red PCB board: the visual effect is strong, often used in high-end or special requirements of products, the production process is complex, the cost is high, and the scope of application is narrow.
3. Blue PCB board: between green and red, the production process is relatively simple, the cost is moderate, and it is widely used in products with cost requirements.
4. Black PCB board: It has good anti-interference ability, which is used more in some equipment that needs to reduce electromagnetic interference, and the production process is complex and the cost is high.
