CSP plate holder

A CSP plate holder for use in dicing a CSP plate into individual pellets, the CSP plate holder comprising:

• a flat plate operative for bearing the CSP plate thereon and having a first surface, a second surface disposed opposite the first surface and a thickness extending therebetween in a thickness direction to define a side surface extending about and between the first and second surfaces, the flat plate having a plurality of pellet areas formed on the first surface with each pellet area allotted to a respective one of the individual pellets, a plurality of through holes extending through and between the first and second surfaces, each through hole allotted to a respective one of the pellet areas, a plurality of suction holes formed on the first surface and partially into the flat plate with at least one suction hole allotted to a respective one of the pellet areas and a labyrinth of suction passages formed interiorly of the flat plate, the labyrinth of suction passages including at least one suction passage opening formed into the side surface and being in fluid communication with each one of the plurality of suction holes and exteriorly of the flat plate at the suction passage opening,
• wherein the flat plate is rectangularly shaped forming two pairs of opposing sides surfaces and the labyrinth of suction passages extends perpendicularly to the thickness direction and
• wherein the flat plate includes at least two suction openings with one suction opening formed into one side surface of a selected pair of side surfaces and a remaining suction opening formed into an opposing side surface of the selected pair of side surfaces.
