2、FILM, WSF-M3G215-A THERMALLY CONDUCTIVE 1. SCOPE The material defined by this specification is a two sided acrylic based pressure sensitive, thermally conductive, adhesive film tape protected with a polyester film release liner on one side. 2. APPLICATION This specification is for an adhesive film t

15、tes to be adhered to should be free of dirt, dust, lint, oils or other contaminants that may reduce the effective adhesion. Adhesive lamination and subsequent bonding should be done in such a manner to reduce entrapped air and insure 100% surface contact. 5.1.3 Application of heat and pressure to the bonded area will decrease the amount of time necessary for the adhesive to reach its ultimate bond strength. 5.2 STORAGE INFORMATION 5.2.1 Tape should ideally be stored at 20 C and 50% relative humidity.
