Material Demands

The production methods within the electronics industry is constantly challenged by the explosive rate of miniaturisation, density and performance increases. The technical requirements on stencils for depositing solder and adhesives has increased correspondingly as manufacturing techniques advance. Stepping, high precision 20 µm apertures, µBGA, wafer bumping, aperture position accuracy whilst improving print quality and durability ... 

... all rely heavily on the supporting characteristics of the base stencil material itself.
