Relife Solder Mask Ink RL-UVH 901G UV?? For PCB Circuit Board

The Relife solder mask Ink RL-UVH 901G is a UV used for protecting and insulating printed circuit boards (PCBs) during the soldering process. It contains the following components:

Photoinitiators: These are chemicals that undergo a chemical reaction when exposed to UV light. In the case of the RL-UVH 901G, the photoinitiators are responsible for initiating the cross-linking reaction that results in the formation of a tough and durable solder mask.

Epoxy Resins: Epoxy resins are used in the formulation of the solder mask to provide mechanical strength, adhesion to the substrate, and resistance to environmental factors such as moisture and heat.

Fillers: The addition of fillers such as silica and alumina helps to increase the viscosity of the solder mask, making it easier to apply and reducing the likelihood of sagging or dripping.

Solvents: The solvent system used in the RL-UVH 901G helps to dissolve the other components and facilitates their mixing and application.

Dyes: Dyes are added to the solder mask to provide a visible color contrast between the masked and unmasked areas of the PCB, making it easier to visually inspect the board for defects or solder bridges.

Overall, the Relife RL-UVH 901G UV solder mask is a complex mixture of chemicals that work together to provide a reliable and durable layer of protection for PCBs during the soldering process.
