Dual layer stencils

Dual layer technology offers performance benefits over conventional stencils. Metal surface is coated with a special resin film to achieve a soft contact to the uneven surfaces of the substrates. Soft contact improves adhesion of solder paste to the substrate and reduces leakage of solder paste into the gaps between the stencil and the substrate.

Dual layer stencils provide very straight lines and enable easy flow of solder paste to the work piece. Final stencil can be adjusted in many aspects, such as stainless steel thickness, coating thickness, offset, opening etc. in order to perfectly fit your application requirements. Resin coating is mainly used for laser-cut stencils, resp. electropolished stencils???
