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.


Flip-Chip families

Flip-chips in different forms and colours, in a PDP-8.

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, etc.

B series

The B stands for Blue. The B series were used as core logic in the higher-end CPUs.

G series

The G stands for Green. The G series were used for "anything with non-standard voltages", I think.

M series

The 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 series

The R stands for Red. Slower logic than the B series, but cheaper. Used extensively in the I/O circuitry of computers.

W series

The W stands for White. These are components that plug into Flip-Chip sockets, but have no logic of their own.
