PCB assembly industry experts answer: In addition to providing color and ink viscosity, controlling the color and flow of the ink, and enhancing the optical properties of the ink, carbon also plays other roles in PCB inks.
1. Enhance conductive properties: Carbon is a basic component element of organic matter and plays a role in increasing conductive properties in PCB ink. By controlling the carbon content and distribution, the connection of wires on the PCB and the transmission of electrical signals can be achieved.
2. Adjust the drying speed of the ink: Carbon plays the role of dissolving and diluting other components in the ink, making the ink easier to spray or print on the circuit board. In addition, carbon can also adjust the drying speed of the ink, allowing the ink to dry quickly during the production process and improving production efficiency.
