Stencil cleaning machine is one of the important equipment in SMT (Surface Mount Technology) production to remove the solder paste and flux residues from the stencil. Solder paste tends to accumulate on the stencil after continuous printing operation that may impact the printing quality. This tool facilitates the cleanliness of stencil and readiness for use in proper manner. This machine functions by removing the residual solder paste from the stencil surface and apertures using cleaning fluids, water-based solutions or solvents. The stencil is inserted in the machine and a controlled cleaning process is started by spraying, applying pressure or by ultrasonic action. This will help to clean off even the smallest solder paste bits. Once the machine is cleaned, it typically also dries the stencil, making it completely dry for the next printing cycle. This helps minimise downtime and optimise production time. New stencil cleaners are fitted with cycles, filters and recycling options for stencil cleaning fluids. These help to keep a standard of cleanliness and minimise waste. The stencil cleaning machine (stencil washing machine) is widely used in the electronics manufacturing, PCB assembly, and SMT production line. This benefits in the improvement of printing accuracy, reduction of printing defects and prolonging the stencil's life, and thus improves the quality of the electronic products.
