I thought I had seen this before...
EEVblog teardown of a ES9000 processor.
Is that a similar package to what the CMOS POWER-2 used? I think I have
one somewhere but never tore into the MCM package.
BY CMOS POWER-2 are you referring to the processor used in the high end
second generation RS/6000 systems?? If so then no, like the ES9000
module the chips are mounted on a ceramic substrate. But in RS/6000
processor the chips sat in a shallow well in the ceramic.? I seem to
recall that the well is filled with oil and a metal lid bonded to the
edges of the ceramic.? the metal lid was the surface the heat sink was
fastened to with a layer of thermally conductive oil between.? I opened
one up one time but I no linger know where it is.
