HDI PCB Board for Inverter with Green Solder Mask

♦ What ​​is Solder Mask?

​​Solder Mask​​ (also called ​​solder resist​​ or ​​solder stop mask​​) is a thin, protective layer of polymer applied to the copper traces of a ​​printed circuit board (PCB)​​ to prevent oxidation, short circuits, and unintended solder connections during assembly.

​​Key Characteristics:​​

1. 1. ​​Prevents Solder Bridging​​
      • Covers exposed copper traces to avoid accidental solder connections between pads or traces.
   2. ​​Protects Copper from Oxidation​​
      • Shields copper from moisture, dust, and environmental damage.
   3. ​​Improves Electrical Insulation​​
      • Acts as a dielectric barrier to prevent electrical shorts.
   4. ​​Enhances PCB Durability​​
      • Resists scratches, chemicals, and mechanical stress.
   5. ​​Aesthetic & Identification​​
      • Typically green (but available in other colors) with silkscreen markings for component placement.
