Method and apparatus for dispensing viscous material

摘要

A novel apparatus for compressing viscous material through openings in a stencil is disclosed. The novel apparatus has a compression head cap which provides a contained environment to direct and to aid the flow of pressurized viscous material through the openings in the stencil. The compression head cap further includes a plurality of members which are selectively and movably disposed within the contained environment and which selectively remove an amount of the material from the environment, effective to prevent the material from being undesirably dispensed by the head cap.
