Publication number: 20100048789Abstract: A resin composition includes brominated epoxy resin of 20-70 wt %, a hardener of 1-10 wt %, a promoter of 0.1-10 wt %, inorganic powder of 0-20 wt %, high thermal conductivity powder of 5-85 wt % and a processing aid of 0-10 wt %. The resin composition possesses high glass transition temperature, high thermal conductivity, and excellent heat resistance as well as flame retardancy. The resin composition, which acts as a dielectric layer of a printed circuit board so as to endow the PCB with high thermal conductivity, is a high thermal conductivity prepreg formed by retting or a high thermal conductivity coating formed by coating. As a result, prompt dissipation of heat generated by electronic components on the PCB is achievable so that service life and stability of the electronic components are improved.Type: ApplicationFiled: January 6, 2009Publication date: February 25, 2010Applicant: NAN YA PLASTICS CORPORATIONInventors: Sung-Yueh Shieh, Dein-Run Fung, Te-Chao Liao, Hao-Sheng Chen
