Definitions
- the present invention relates to a low dielectric resin composition.
- FPC flexible printed wiring boards
- the frequency of signals has increased.
- FPCs are required to have excellent properties such as adhesion, heat resistance, and circuit embedding properties. Therefore, in addition to being excellent in adhesion, heat resistance, circuit embedding property, and the like, FPC materials are required to have excellent low dielectric properties such as low dielectric constant and low dielectric loss tangent in a high frequency region. ing.
- Patent Document 1 discloses a cyanate ester resin composition having excellent dielectric properties and heat resistance and good flame retardancy, and a prepreg and a metal foil-clad laminate using the cyanate ester resin composition.
- Patent Document 2 discloses that a flame retardant adhesive composition containing an imide bond-containing urethane resin, an epoxy resin, and a flame retardant as essential components is compatible with both adhesiveness and electrical insulation, and has both flexibility and heat resistance.
