Package sample for single in-line (SIL) devices. The big flange is a 'heat sink' that dissipates excessive heat that would destroy the IC if it was not vented off. Attribution: I, NobbiP.


A Soviet MSI nMOS chip made in 1977, part of a four-chip calculator set designed in 1970. Early USSR made integrated circuit. The tiny block of semiconducting material (the "die"), is enclosed inside the round, metallic case (the "package").


Small-outline integrated circuit. This package has 14 "gull wing" leads protruding from the two long sides and a lead spacing of 0.050 inches.

Fairchild Briefing on Integrated Circuits-0

[Recorded: October, 1967] This half hour color promotional/educational film on the integrated circuit was produced and sponsored by Fairchild Semiconductor Corporation and first shown on television on October 11, 1967. In the film, Dr. Harry Sello and Dr. Jim Angell describe the integrated circuit (IC), discuss its design and development process, and offer examples of late 1960s uses of IC technology. It was one of the early forerunners of what would become a worldwide high-tech industry, as evidenced in this short promotional film. Catalog Number: 102651800 Lot Number: X3929.2007

Project Tinkertoy (IC Precursor) 1953 US Navy; Automated Manufacturing of Modular Electronics

Electronics playlist: more at: Project Tinkertoy was an effort begun in 1950 by the US National Bureau of Standards to devise a system for automated manufacturing of electronic devices built up from modular subsystem components. The resulting products were not smaller or lighter than hand-assembled electronics of the time, but were thought to be more reliable and required less skilled labor. A fourth notch placed between two of the riser wire notches on one edge is provided for use in indexing the wafers to the correct orientation during the assembling processes...
