Abstract

1476404 Component assemblies SHARP KK 5 June 1974 [6 June 1973] 24896/74 Heading H1R [Also in Division G4] Substrate 14 bearing the printed circuitry, key contacts, i.e. chips 144, 146 and display unit 148 of, e.g. a desk-top calculator is at least in part flexible so as to minimize its space requirements. Setting of the angle of the display unit 148 is also permitted. The i.e. chips may be mounted directly on the substrate by flip-chip or beam-lead bonding, or on a secondary substrate, which may be also be flexible, mounted on the substrate with e.g. solder connections between the circuitry. The chips are preferably encapsulated after mounting. The part of the substrate bearing the key contact areas may be fixed in relation to the casing of the assembly while the part bearing the display unit may be fixed in relation to a hinged lid for the casing (Fig. 3, not shown). The secondary substrate may be detachably secured to the substrate, e.g. by stitching (Fig. 7, not shown) to permit replacement of a defective i.e.
