Colors of PCB Boards

When it comes to PCB boards, one of the most noticeable features is the color of the board itself. The color of the surface finish, such as green, blue, red, or black, can provide insights into the board’s characteristics and manufacturing process.

1. Green PCB Boards

Green PCB boards have a long history and remain the most popular choice due to their cost-effectiveness. Many manufacturers prefer green boards for their products, such as touch control panels.

2. Importance of Green Color in PCB Fabrication

During PCB fabrication and SMT processes, the green color of the board plays a crucial role. Green boards perform better under yellow light, which is essential for processes like solder paste application and component placement.

3. Advantages of Green PCBs

Green PCBs are favored by manufacturers due to their ease on the eyes under strong light. While other colors like red, yellow, blue, and black are common, green boards are less straining for visual inspections.

4. Blue and Black PCBs

Blue and black PCBs offer unique characteristics due to the elements used in their composition. However, green PCBs are considered more environmentally friendly and easier for instrument identification during production processes.

5. Significance of PCB Color

Since the 20th century, the industry has recognized the importance of PCB color, with green boards often associated with high quality. Leading manufacturers have set a trend by choosing green as the standard color for high-end PCB designs.
