Apparatus to minimize paper particulate from paper based carrier tape reel

Abstract

A reel adapted to have chip carrier tape wound thereabout includes at least one flange and a plastic rail. The flange is made from a paper-based material. The plastic rail is attached an interior major surface of the paper flange. The plastic rail may extend along a radial direction of the flange and/or along a circumferential direction of the flange, for example. The plastic rail may be substantially straight and/or curved, for example. The plastic rail is preferably made from a static dissipative material. The plastic rail reduces or eliminates the generation of paper particles from the paper-based flange while reeling/unreeling chip carrier tape from the reel.

What is claimed is:  
     
         1 . A reel adapted to have chip carrier tape wound thereabout, comprising: 
 a drum portion;    a first flange portion extending from the drum at a first end of the drum in a generally radial direction, the first flange being made from paper material;    a second flange portion extending from the drum at a second end of the drum in a generally radial direction, wherein a tape storing region is formed between the first and second flange portions; and    a plastic portion attached to the first flange portion and extending from the first flange portion into the tape storing region.    
     
     
         2 . The reel of  claim 1 , wherein another plastic portion is attached to the second flange portion and extends from the second flange portion into the tape storing region.  
     
     
         3 . The reel of  claim 1 , wherein the plastic portion is removably attached to the first flange portion.  
     
     
         4 . The reel of  claim 1 , wherein the plastic portion is permanently attached to the first flange portion.  
     
     
         5 . The reel of  claim 1 , wherein the plastic portion comprises generally radially extending spokes.  
     
     
         6 . The reel of  claim 1 , wherein the plastic portion comprises at least one round-shaped rail that is generally concentric with the drum portion.  
     
     
         7 . The reel of  claim 1 , wherein the plastic portion is formed from a band adapted to fit over an outer edge of the first flange portion.  
     
     
         8 . The reel of  claim 1 , wherein the plastic portion is disc shaped and mounted against an interior major surface of the first flange portion.  
     
     
         9 . The reel of  claim 1 , wherein the plastic portion is a layer formed on the first flange portion.  
     
     
         10 . A package of semiconductor chips, comprising: 
 chip carrier tape having a series of pockets;    a plurality of semiconductor chips located in at least some of the pockets; and    a reel having the chip carrier tape wound thereabout, the reel comprising a drum portion,    a first flange portion extending from the drum at a first end of the drum in a generally radial direction, the first flange being made from paper material,    a second flange portion extending from the drum at a second end of the drum in a generally radial direction, wherein a tape storing region is formed between the first and second flange portions, and    a plastic portion attached to the first flange portion and extending from the first flange portion into the tape storing region.    
     
     
         11 . A reel adapted to have chip carrier tape wound thereabout, comprising: 
 a drum portion;    a first flange portion extending from the drum at a first end of the drum in a generally radial direction, the first flange being made from paper material;    a second flange portion extending from the drum at a second end of the drum in a generally radial direction, wherein a tape storing region is formed between the first and second flange portions; and    a non-paper layer formed on the first flange portion and extending from the first flange portion into the tape storing region.    
     
     
         12 . The reel of  claim 11 , wherein the layer is made from an anti-static polyethylene material.  
     
     
         13 . A reel adapted to have chip carrier tape wound thereabout, comprising: 
 a drum;    a first paper flange attached to a first end of the drum;    a second paper flange attached to a second end of the drum; and    a non-paper disc located about the drum between the first and second flanges, the disc having a hole formed therein, and the drum extending through the hole in the disc.    
     
     
         14 . The reel of  claim 13 , wherein the disc is made from an anti-static plastic material.  
     
     
         15 . A reel adapted to have a chip carrier tape wound thereabout, comprising: 
 a flange made from a paper-based material; and    a plastic rail attached an interior major surface of the paper flange.    
     
     
         16 . The reel of  claim 15 , wherein the plastic rail extends along a radial direction of the flange.  
     
     
         17 . The reel of  claim 15 , wherein the plastic rail extends along a circumferential direction of the flange.  
     
     
         18 . The reel of  claim 15 , wherein the plastic rail is substantially straight.  
     
     
         19 . The reel of  claim 15 , wherein the plastic rail is curved.  
     
     
         20 . The reel of  claim 15 , wherein the plastic rail is made from a static dissipative material.
