How to Clean and Scrap SMT Stencils
1. Disassemble the stencils. Remove any remaining welding paste from the front of the stencil using a scraper and throw away the dried paste. 2. Spray a cleaning agent evenly onto the stencils and wipe them with the wiping paper until the welding paste is gone and there are no impurities visible on either the upper or lower side of the stencil. 3. Wipe the stencils on both the upper and the lower side with two pieces of wiping papers, using a cleaning agent.
