Abstract

PURPOSE:To facilitate sealing in a heating atmosphere of less than the melting point of metal thin-film layers and achieve the improvement in overall performances by mutually bonding a circuit substrate and a cap through the low melting point metal thin-film layers in a miniature thin type crystal wristwatch.
