Flip Chip (trademark)

Flip-Chip modules were used in the DEC PDP-7 (referred to in documentation as the "FLIP CHIP"), PDP-8, PDP-9 and PDP-10, beginning on August 24, 1964. The trademark "Flip-Chip"' was filed on August 27, 1964.

There appeared to be some confusion inside DEC at the time, as various manuals refer to it as "FLIP CHIP", "Flip Chip", "FLIP-CHIP", and "Flip-Chip", with trademark and registered trademark symbols.

The modules were called Flip-Chip because early versions of some of these modules used flip chip mounting for individual diode chips, but these were eventually found to be unreliable so conventional discrete diodes replaced the flip chips. In later computers where DEC used integrated circuits, they continued to use "Flip-Chip" despite the fact that actual flip chip mounting was not used, so that they could retain their trademark. Eventually, on June 6, 1987, the trademark was allowed to expire.

Famous quotes containing the words flip and/or chip:

    By act of Congress, male officers are gentlemen, but by act of God, we are ladies. We don’t have to be little mini-men and try to be masculine and use obscene language to come across. I can take you and flip you on the floor and put your arms behind your back and you’ll never move again, without your ever knowing that I can do it.
    Sherian Grace Cadoria (b. 1940)

    Look Johnny, Spig just joined the Navy. I’m married to it. I run the mess hall. I swab the deck. I chip the rust. You’re afraid that they’ll kick Spig out of the Navy. I’m afraid that they won’t.
