Abstract
A method of stencil printing includes printing a layer of non-sag adhesive onto a first substrate, adding topography to the layer of non-sag adhesive, and contacting the layer of non-sag adhesive with a second substrate. The second substrate initially contacts only about 5% or less of exposed surface area of the layer of non-sag adhesive.
