发明名称 WINDOW CLAMP TOP PLATE FOR INTEGRATED CIRCUIT PACKAGING
摘要 A device and method for minimizing the forces that may compromise a lead frame mount to a support structure in an integrated circuit die package during various packaging method steps. When a window clamp is used to provide pressure during a lead frame bonding step or during a wire bonding step during packaging, the vertical force applied by the window clamp may be transferred in lateral direction by the physical contour of the top plate of the support structure. By changing the physical contour of the top plate of the support structure, such as by disposing a specific kind of contoured protrusion, one may minimize or eliminate the lateral forces that act against achieving a solid bond of the lead frame to the support structure. Further, during wire bonding, the same minimization or elimination of lateral forces lead to improved wire bonding.
