Electropolished stencils

The aperture wall structure of laser cut stencils is rougher than the other techniques due to the melting effect of the laser beam. Electropolishing removes the micro-burrs associated with laser cutting and also passivates the steel. Resulting smooth aperture walls promotes easy transition of paste from the stencil to the substrate, while smooth metal mask surface improves the rolling action of the solder paste.

Electropolished stencils keep the precision of laser cut stencils together with the paste release characteristics of high-quality electroformed stencils. Customers rely on this surface technology when printing high density layouts comprising very small apertures, along with requirement of short lead time?
