Abstract
Electronic calculators are manufactured by use of a flexible insulative carrier, the carrier being a tape-like-plastic substrate a single length of which is sufficient to manufacture a plurality of the electronic calculators, wherein conductor patterns are formed on the carrier, a keyboard is formed on the carrier using selected portions of the aforementioned conductors as keyboard switch contacts and semiconductor devices are interconnected with selected conductors formed on the carrier.
Claims26
A method of manufacturing an electronic calculator comprising:
- (a) forming a pattern of conducting stripes on a flexible substrate;
- (b) forming a plurality of indentations in said substrate intersecting selected portions of said conducting stripes in said pattern;
- (c) folding a portion of said substrate back on itself to form a keyboard utilizing the indentations and selected conducting stripes as keyboard switches;
- and
- (d) connecting a tape-mounted semiconducting device and a display device to said flexible substrate.
A method of manufacturing an electronic calculator comprising:
- (a) forming a pattern of conducting stripes on a flexible substrate;
- (b) forming another pattern of conducting stripes on an insulating sheet;
- (c) forming a plurality of indentations in at least one of said substrate and said sheet, said indentations intersecting selected portions of said conducting stripes;
- (d) bonding said sheet to said substrate, selected conducting stripes on said substrate being registered with selected conducting stripes on said sheet;
- and
- (e) connecting a tape-mounted semiconducting logic device and a display device to said flexible substrate.
A method of manufacturing an electronic calculator comprising the steps of:
- (a) forming a pattern of conductive stripes on a flexible substrate;
- (b) connecting the leads from a tape-mounted semiconducting logic device to selected conducting stripes on said substrate;
- (c) connecting selected conducting stripes on said substrate to a keyboard means;
- and
- (d) connecting selected conducting stripes on said substrate to a display device.
