Sawa Stencil Cleaners are widely used in the Japanese Electronics Industry to ensure high yields when screen printing solder paste onto printed circuit boards. Normal cloth wipe cleaning of stencils cannot completely remove solder paste especially in fine pitch applications as a small amount of solder balls have a tendency to adhere in the corners of the apertures.

Sawa Stencil Cleaners are able to completely remove solder paste utilizing ultrasonic vibration and require no special solvents as they work effectively with isopropyl alcohol, water base solvent or any other solvent.
