Abstract:
Creating surface variations on a stiffener in a stack reduces inter-stiffener sticking and stiffener stack tilt in pick and place media. The surface variations provide one or more airgaps that reduce inter-stiffener surface contact, provide space for contaminants and/or provide an averaged surface height due to surface roughness.
