Product type
PCB solder mask ink is a specialized coating used on printed circuit boards to insulate and protect the conductive traces from environmental damage and short circuits. It is typically made from epoxy or acrylic resins, which provide excellent adhesion and durability. The ink is applied to the PCB surface and cured to form a solid layer, ensuring that only the necessary areas remain exposed for soldering components.

| Color options | Green, black, blue, red, and custom colors |
| Curing method | Thermal or UV curing |
| Thickness range | 10 to 30 microns |
| Viscosity | 100 to 500 cP |
| Shelf life | 6 to 12 months when stored properly |
When selecting PCB solder mask ink, consider the specific requirements of your application, including the type of PCB material and the environmental conditions it will face. Specify the desired color, thickness, and curing method to ensure compatibility with your production process. It's also important to inquire about the ink's adhesion properties and any relevant certifications for safety and performance.
