Hi All,

     Does anyone out there have any information or specification details on
     "S-glass" fibre reinforcement material as used in PCB laminates, and
     what does the "S" stand for?

     There are TCE (sorry CTE for you guys!) advantages with its use, and
     depending on the resin system it is used with, Er advantages also, but
     I am looking specifically to identify and understand the differences
     between "S-glass" fibre material and the more conventional "E-glass"
     fibre material. (I understand "E" stands for "Electronics" Grade???).

     How many people use S-glass?

     What benefits do you see?

     Any comments appreciated.
