ABSTRACT:
An electronic device (12) is encapsulated by a curable material (15) which, prior to cure, comprises sixteen to twenty-three weight percent of a silicone resin, forty-six to seventy-three weight percent of silicon dioxide, four to fifteen weight percent of silicon hydride, and six to twenty-five weight percent of xylene. The silicone resin is selected from the group consisting of polydimethylsiloxane, polymethylphenylsiloxane, and a mixture of polydimethylsiloxane and polymethylphenylsiloxane. The silicone resin contains a platinum catalyst and has vinyl and/or hydride functional components.
