soldeermasks
Soldeermasks are protective coatings applied to printed circuit boards (PCBs) to prevent solder from bridging between adjacent components during the soldering process. They also protect the copper traces from environmental damage and oxidation. The mask is typically made of a polymer material, such as epoxy or silicone, which is cured under UV light or heat. This process creates a hard, durable layer that can withstand the high temperatures of soldering.
The application of soldeermasks is a critical step in PCB manufacturing. It is usually applied using a
