Pretty advanced looking Soviet flip-chip SMD IC from 1991.
Refrigerator:
Taken from some soviet tech (a TV i think), was originally a SIL package. The substrate is ceramic, after breaking it apart it was pink-ish in color. Backside of the substrate contains what looks like three crystal oscillators. There are SMD devices soldered to what looks like printed traces. The star of the show is the flip chip IC in the middle.
Date code says 1991, pretty neat stuff.
I captured as much detail as i could with my phone camera. If electronupdate or anyone else wants to take more detailed die shots and maybe analyze the IC i can send it over.
Ps: Oh and by advanced i mean the package of the chip. The device itself is probably very simple.

IBM did it in the 1960s (I'm sure the Soviets did it earlier as well):

IC packaging and hybrid manufacturing is full of weird technologies that seem too advanced for us common folk for the era :)

It's audio IF amplifier with demodulator. Those things are ceramic filters.
David Hess:
And Tektronix was doing it at least by the late 1960s; all of their single package vertical amplifiers use hybrid construction.

Was this common in consumer gear?
