The color of printed circuit board

Printed circuit board is an indispensable part of electronic products. It is the basic material that connects circuits together and is used to support electronic components and circuit systems.

Common printed circuit boards include green, red, blue, black, and white. The first is green circuit board, which is the most common and classic color. It is generally used to produce ordinary electronic products, with stable performance in use, relatively inexpensive prices, bright colors, beautiful appearance, and easy maintenance

Red circuit boards are widely used, and can be used in some high-end products, such as lighting and avionics products.

Compared to green and red circuit boards, blue circuit boards have stronger corrosion and wear resistance, and are used for equipment in special fields.

Black circuit boards are a more eye-catching type of circuit board. Due to their relatively black color, it is difficult to clearly see the the circuit patterns, which can increase the difficulty in maintenance. However, the color of black circuit boards is relatively dustproof, and is commonly used in high-end products such as instruments and home theaters.

White can increase the wavelength of reflected light and reduce heat and damage within the circuit board, making it suitable for making some chip circuits.

Ink with different colors essentially plays a role in preventing substrate oxidation, but due to optical factors such as color wavelength, the role of ink with different colors is differentiated and different. We can choose the appropriate color of the circuit board according to the different uses of the product, so as to ensure that our products are more accurate and reliable.
