Flip-Chip was a DEC registered trademark, named after the "flipchip" component mounting technique which quite rapidly faded from fame. The name was retained although the majority of Flip-Chips never really were flipchip-mounted as it became apparent that the flipchip mounting technique was highly unreliable. Flip-chips 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.
Contents
Naming
There appeared to be some confusion inside DEC at the time, as various manuals refer to it as "FLIP CHIP", "Flip Chip", "FLIP-CHIP", "Flip-Chip" and "Flip Chip", with trademark and registered trademark symbols.
Flip-Chip families
The various families were colour-coded, and the first letter denoted a colour, which was also visible on the handle.
A series
The A stands for Amber. The A series were used for analog functions - ADCs, DACs, amplifiers etc.

} B seriesThe B stands for Blue. The B series were used as core logic in the higher-end CPUs. G seriesThe G stands for Green. The G series were used for "anything with non-standard voltages", I think. M seriesThe M stands for ...? I'll have to find that out. Don't know what defines this, but I think it's "TTL-level logic". R seriesThe R stands for Red. Slower logic than the B series, but cheaper. Used extensively in the I/O circuitry of computers. W seriesThe W stands for White. These are components that plug into Flip-Chip sockets, but have no logic of their own. |
