Solder Mask Ink

Solder Mask Ink is a specialized coating designed to protect the copper traces on printed circuit boards (PCBs) from oxidation and contamination. It is widely used in the electronics industry for its excellent adhesion, chemical resistance, and thermal stability. This ink also serves as a colorant, providing clear identification of components and enhancing the aesthetic appearance of the board. Key properties include high durability, flame retardancy, and UV stability, making it an essential material in PCB manufacturing.
