Sheet for embossed carrier tape

Abstract

It is to provide an embossed carrier tape and a sheet for an embossed carrier tape suitable for high-speed mounting. A sheet for an embossed carrier tape excellent in high-speed mounting properties can be obtained by making the tear strength of the sheet at least 105 N/mm as defined in JIS-K-7128-3.

1 . A sheet for an embossed carrier tape having a tear strength of at least 105 N/mm as defined in JIS-K-7128-3.  
     
     
         2 . The sheet according to  claim 1 , which has a surface resistance of at least one surface of at most 10 12  Ω/□.  
     
     
         3 . The sheet according to  claim 2 , which is a single-layer sheet.  
     
     
         4 . The sheet according to  claim 2 , which is a multi-layer sheet.  
     
     
         5 . The sheet according to  claim 4 , which has a base layer and an electrically conductive surface layer.  
     
     
         6 . The sheet according to any one of  claims 1  to  5 , which uses a thermoplastic resin.  
     
     
         7 . A sheet for an embossed carrier tape which uses a thermoplastic resin, which has a base layer and a surface layer having a surface resistance of at most 10 12  Ω/□ on both sides of the base layer, and which has a tear strength of at least 105 N/mm as defined in JIS-K-7128-3.  
     
     
         8 . An embossed carrier tape which comprises the sheet as defined in any one of  claims 1  to  7 .
