Heat sinks holding kit and storage rack for semiconductor chip

Abstract

A heat sink holding kit and storage rack for semiconductor is disclosed. A plurality of heat sinks and chips are molded die to form a package, and a holding kit and a storage rack are used to rapidly arrange the heat sinks within the cavity of a mold.

I claim:  
     
         1 . A heat sink holding kit and a storage rack for semiconductor chip, the holding kit comprising 
 (a) a top fixing block being square in shape having a U-shaped stepped hole at the center and the opening ends of the stepped hole being provided with through hole for the insertion of an insertion peg and the top end of the stepped hole being provided with screw hole for the positioning of positioning ball positioning device with elasticity;    (b) a bottom fixing block being a rectangular shaped block having a base edge for positioning, and having a rectangular through hole suitably for heat sinks at the top face thereof and a circular shallow slot for the heat sinks to rotate within the circular shallow slot; and    (c) a rotating handle having a vertical hollow cylindrical body provided with a forming slot at the center thereof to allow the insertion of heat sinks from the storage rack so as to provide storage space for the heat sinks and a shallow slot being located at the bottom face of the hollow cylindrical body forming by the revolution of 5 degree by the forming hole, the bottom of the cylindrical body being a protruded edge so that the edge can engage with the stepped hole and the bottom face of the cylindrical body and the top face of the positioning block without forming a gap, the lower side of the hollow cylindrical body provided with four equally distributed positioning holes which match the positioning device of the upper fixing block, i.e., in the course of positioning the heat sinks aligned with the rectangular through hole of the lower positioning block so as to disperse the heat sinks.    
     
     
         2 . The holding kit and the storage rack as set forth in  claim 1 , wherein the storage rack comprises 
 (a) a base board being rectangular in shape having a plurality sets of four binding holes on the top face thereof as a set of locking hole;    (b) a pair of supporting boards mounted at the two lateral sides of the base board and fixed to the base board with screw, and a screw hole being provided on the supporting board for the screwing of an upper covering plate;    (c) the upper covering plate being a flat plate mounted at the top face of the supporting board to cover the end face of a guiding peg located on the locking hole so as to prevent dislocation of the heat sinks and isolation blocks; and    (d) a plurality of guiding pegs mounted to the locking hole on the base board allowing the long heat sinks passed through the guiding peg alternately and stacked to form a column-like structure having inserted with the isolation block; and the guiding block being inserted into the stacked heat sinks with a rotating handle and being able to withdraw from insertion.    
     
     
         3 . The holding kit and storage rack as set forth in  claim 1 , the storage rack includes 
 (a) a bottom plate being a rectangular in shaped having a plurality of equally distributed binding holes with which form as a unit to form a locking hole;    (b) a pair of supporting board located at the two sides of the bottom plate and a shoulder section being formed at a recess on the inner side surface of the board for the mounting of the bottom plate and a side hole being mounted with screw for mounting with the bottom plate the bottom plate being placed horizontally and the binding hole faced upward and the supporting board being mounted at the two lateral sides.
