Abstract
A segmented squeegee blade is provided for optimizing the flow of a depositable material such as viscous liquid or flowable medium such as solder paste, adhesive, or the like through a stepped stencil onto a substrate. The blade has a plurality of segments adapted for substantially independent deflection with respect to each other. The blade segments deflect and conform to a stepped surface or stencil to provide for more consistent deposition of flowable material. The squeegee blade also is adapted for use with stencils having more than two step levels. The segmented squeegee blade enables component density to be increased as compared to conventional methods.
