| 20100048789 | Resin composition of high thermal conductivity and high glass transition temperature (Tg) and for use with PCB, and prepreg and coating thereof - 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. | 02-25-2010 |
| 20100163783 | High thermal-conductive, halogen-free, flame-retardant resin composition, and prepreg and coating thereof - A high thermal-conductive, halogen-free and flame-retardant resin composition used as a dielectric layer of a printed circuit board comprises 5% to 70% of phosphorus-containing epoxy resin, at most 50% of multifunctional or bifunctional epoxy resin, 1% to 20% of curing agent, 0.01% to 10% of accelerant, at most 20% of inorganic powder, 5% to 85% of high thermal conductivity powder and 0.01% to 10% of processing aids, which resin composition has excellent thermal conductivity, heat resistance and flame retardancy as well as being environmentally friendly for free of halogen flame retardant and no toxic or corrosive gases when burning; the resin composition is used to form as a high thermal-conductive prepreg by impregnation or form as a high thermal-conductive coating by coating and then further used as a dielectric layer on a printed circuit board for demonstrating if electronic components formed thereon the printed circuit board has high thermal-conductivity and efficient heat dissipation capable of improving long service life and enhanced stability of electronic components. | 07-01-2010 |
