White UV Protective Coating for PCB

A solder mask is used to create a protective layer on a printed circuit board (PCB). Care must be taken to avoid applying it on connection paths and soldering points.

This 100g white UV protective coating suitable for PCB turns the board white when exposed to UV light. Using a PCB solder mask protects the board against oxidation and enhances its appearance.

Shake the solder mask well before use, and keep in mind that the UV protective coating is not dilutable.

Applications of the PCB solder mask

1. PCB design
2. PCB fabrication
