PCB Solder Mask (also known as solder resist) is a protective polymer layer applied to printed circuit boards to prevent solder bridging, resist oxidation, improve insulation, and ensure long‑term reliability in SMT assembly and industrial applications. This guide covers definitions, types, colors, processes, DFM rules, IPC standards, testing, and troubleshooting for engineering and procurement teams…
This guide covers everything about PCB solder mask (solder resist), including its functions, types, colors, application processes, thickness standards, IPC testing, and assembly compatibility. Learn how solder mask protects circuits, prevents solder bridging, and improves reliability for industrial and high-density PCBs. We explain how to select the right solder resist for rigid, flexible, and high-speed…
