          - Brief Introduction: 
 
          - The Quad Flat Pack/Thin Quad Flat Pack is a plastic package with a square or rectangular body with leads on all four sides in a gull-wing configuration. Designs with "dimples" (half-etched holes) on the back side of the pad provide the mechanical adhesion to prevent delamination. Different pad designs exist to further enhance package reliability, while designs with a dual-pad lead frame are available to minimize cost.
