Abstract
A shock absorber pad for absorbing shock caused by separation of a perforated sheet mask from a surface on which a pattern of a screened medium has been formed by forcing a viscous material through the mask which includes a plurality of protuberant features which have a separation determined in accordance with a nominal viscosity of the screened medium and a transverse feature dimension based on characteristic stand-off spacing or mask feature size increases pattern quality and extends mask life. Hollow pattern features also improve pattern quality by reducing pad contact area with the mask during separation while allowing the pad features to span mask features. Methodology of shock absorber pad design and adjustment of screened medium viscosity to pad feature spacing are included.
