    Abstract: Laminated synthetic mica articles are disclosed that have particular applicability as substrates in electronic components. The articles comprise a core of stacked and consolidated, synthetic mica sheets that are impregnated with resin, and a copper foil sealed to a face on the article. Adherence of the copper foil is enhanced by use of a micaceous facing layer and bonding sheet, both being resin-impregnated and the resin cure being advanced beyond the normal B-stage level before assembly. Insulation resistance is enhanced by providing an advanced resin coating on the copper foil before assembly. Use of a bismaleimide triazine and epoxy mixed resin is also disclosed whereby a transformation temperature (Tg) of about 200°C. is obtained.

    Abstract: The invention aims at providing a resin composition for electronic parts which is in great demand as a circuit board material for electric and electronic equipments, and which has a low dielectric constant, low dielectric dissipation factor and a thermal resistance. This resin consists of a thermoplastic resin or a thermosetting resin, and wollastonite or zonotolite, fibrous material containing CaO.SiO₂ as a main component, mixed as reinforcing fiber with the resin at a mixing ratio of 5-60 % based on the total weight of the resin and fiber.
