摘要：
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.
