Resin composition, copper-clad laminate and printed circuit board for use therewith
A resin composition includes (a) an epoxy resin; (b) a benzoxazine (bz) resin; (c) a styrene maleic anhydride (sma) copolymer; and (d) a polyester. The resin composition includes specific ingredients of a polyester and is characterized by specific proportions thereof so as to achieve a low delta tg value of copper clad laminates manufactured in accordance with the resin composition and attain a low dielectric constant, a low dielectric dissipation factor, high heat resistance, and high fire retardation of the copper clad laminates and printed circuit boards manufactured in accordance with the resin composition..

Three-phase capacitor formed by two aligned cylinders with overpressure disconnection
Three-phase capacitor formed by two cylinders where each of the cylinders comprises an outer part which corresponds to a capacitor (1) and (2) while the inner part of each cylinder corresponds to a capacitor (3) and (3′) and which are connected in delta with phases (a), (b) and (c), where each capacitor is separated from the adjacent of each cylinder by means of an insulating material which allows the movement of the inner part with respect to the outer one of each cylinder in case of overpressure, which causes the breakage of the connections made in a particular manner, the breakage of the conductive coating layer (7) which connects armatures (3.1) and (1.2); the breakage of the conductive coating layer (8) which connected armatures (2.2) and (3′.2), the breakage of the connection of connection cable (6) with phase (c), serving as an effective means of protection against internal overpressures.. .
