1. Product Overview
WonderMASK WSOL Washable Solder Mask (Product #2204) is a water-soluble temporary solder mask designed for use in closed-loop PCB assembly systems. It provides reliable protection of components and through-holes during wave soldering and assembly processes. The mask is safe on ion beds and filters, non-corrosive, low-odor, and fully RoHS compliant. It cures quickly at moderate temperatures and can be easily removed with inline or batch water-based cleaning systems, making it ideal for high-throughput production.
2. Applications
Thru-hole masking to prevent soldering of open holes
Temporary adhesive to tack down components on double-sided PCBs
Protection during wave soldering, including lead-free processes
Any PCB assembly requiring temporary, water-removable masking
