The thermal conductance/capacitance ratio looks pretty constant for
the various parts, around 1.5 pF per w/K. That depends mostly on the
material, AlN. BeO is a little better, but it's toxic.

Diamond is really good.

Really fast circuits need high power dissipation in tiny parts. So
sometimes they need good cooling with low capacitance.

Don't usually have to worry about the pF. Spend most of my time nowadays
on the other end of the spectrum dealing with 1/f noise and counting
statistics.

He wants to produce results where X

yeah, that's more clear.

ISTR that many 60s/early70s books did. A neuron relating
to "ease of manufacture" is firing, but the SNR is too low
for comfort.

The period described by Widlar is almost like the
"Cambrian explosion" in that he describes some odd
structures that seem to have died out without leaving
a trace.

Thanks for the combined version.

So I notice that he liked to use PNPs a lot.

Not sure if I knew or not, but, when those guys at Bell Labs made the
first transistor, was it a PNP or an NPN type ?

I seem to recall the first one was point contact so I believe they only
form PNP transistors.

Pyrolytic graphite tape is neat stuff too.

It's electrically conductive, isn't it?

We need diamond, preferably isotopically pure diamond.

Pyrolytic graphite can be purchased with insulation on one or both
sides. The insulated adhesive tape is meant for chilling tiny SMDs and
circuit boards where direct soldering to metal bulk isn't practical.
Naked pyrolytic graphite adheres very well with epoxy.

Given that one wants thermal conductivity and electrical insulation,
the graphite just makes things worse. The adhesive is doing all the
work.

It may be useful as a lateral heat spreader, if the adhesive is on one
side. But copper can do that, too.

AlN and BeO are good thermal conductors and electrical insulators.
They are available metalized, for soldering. The IMS things are cute,
stocked parts.

Diamond is much better. It's surprising that nobody has come up with a
process to make affordable bulk diamond.

It's already affordable where you really need it.
People wouldn't be making diamond heat sinks if there wasn't any market
at all, but it will be a while before it shows up in consumer products.

Exactly. So pick one. Both will work well. Graphite will be lighter
and more conductive.

I, in fact, made sure that any nym I used was easy connectable to the

mere mood modifiers for a given post.

But that is beyond your capacity to grasp, along with a large number of
others in Usenet. There was never any trolling. Just a bunch of
childish pussies, like you, and John S and the like. So, I am a troll
