Address,
     
     Can anyone supply technical laymen information on Speed Ball and 
     Polyimide Laminates.  I would also appreciate any test data (e.g. 
     thermal, humidity, solder, tensile strength tests) that have been 
     performed to prove the long reliability of these materials.  A 
     material characteristics sheet is also helpful.  Thank you.
