Abstract: In a process for producing calculator printed circuit boards, a pallet consisting of a plurality of printed circuit boards are interconnected by snapaway perforated edges at the adjacent side of the boards, so that the pallet consisting of plural boards is processible as a whole. Electrical elements or components have their terminals received through openings in the printed circuit board, which insertion is by machine utilizing a pantographic locating principle. Components are also assembled on the board by hand insertion. After inserting selected electrical components at the desired locations, and masking other locations, the electrical connections are then treated by fountain soldering to form electrical connections between the leads and the printed circuit. The soldering occurs to the pallet as a whole. The individual boards are then snapped apart and the board has enough dimensional stability so that it is rigidly clamped on a fixture and passed over a routing blade at a predetermined slight clearance therefrom so that all of the excess lead sections are trimmed from the subsurface of the printed circuit substrate. Further electrical devices can then be added and soldered in place and the printing circuit board together with its electrical components can then be positioned within a container for a computer application. The described process incorporates minimal handling and incorporates high speed machine assembly techniques wherein multiple operations occur simultaneously or repetitively at high speed.

Abstract: In a small hand-held calculator the electroluminescent display is in the form of a series of light emitting diodes (''''chips'''') which are received on a printed circuit board. The electric signal output of the calculator circuit is communicated to the display through a series of pins which are stake mounted on a printed circuit board and the projected ends of these pins serve the dual purpose of communicating electric signals which determine the display and also serve to mount the printed circuit board of the display and its associated components. The pins are inclined so that the display can be disposed at whatever viewing angle is desired. Thus, although the small calculator may lie flat on a desk or other support surface, the plane of the display is disposed at an angle making viewing much more convenient, that is, at an angle approaching perpendicularity to the line of vision of the viewer. By utilizing the pins both as electrical signal communicating means as well as mounting means it is possible to locate the display at whatever angle is desired and in a much more convenient and economical manner.
