Why is electronics so complicated?

It's hard to tell, since he isn't very good at the job.

Where does the other end of the hose attach to, your head?

I don't hide my name, my location, my business, my products, my education, or my schematics. YOU gutlessly hide everything. Stand and deliver yourself!

Your character is "coward." But don't be upset, it's common enough.

What's your real name, coward?

John

That's as good as any.

In the first post I made where I referenced it, your hop trail went through there.

Cedar Rapids is much closer. That was a cursory glance. I could do far better, but I would have to lower myself 160 IQ points down to your retarded, stalk boy, 20 IQ mentality.

AlwaysYellow? YellowBellows?

I am not at liberty to discuss my identity.

I am also not in any Mood to tell a sub-human fucktard like you such info.

If it were not for your retarded behavior, you would garner other than a sub-human rating, but since you insist on posting bullshit on a constant basis, you get no quarter.

You are a sub-human fucktard that should be erased. Sad thing is that the piggery is too goddamned retarded to know that killing a sub-human is not a crime. It is a community benefit. Sadly though, they are nearly as stupid as you are.

His scat fetish is getting really, really bad.

Heat spreaders are a conduction mass sink device, and surface quality has nothing to do with it.

You bond it to the surface of the box, just as was stated, and then you attach the source, just like you would attach your transistor or whatever source to any other sinking device.

The ideal spreader is thick enough to spread the heat over the target width or a width that is wide enough to make the external interface efficient enough to sink the source OVER TIME. It is possible to make it a small, pyramidal enlargement of the original heat source package conduction tab/surface. There is a point at which you have overcome the thin box wall issue and need no larger spreader.

On the OUTSIDE, however, you are in the realm of conduction cooling as you need to sink that internal spreader footprint plus a slight bit larger into a MASS that either leads to MORE mass, or an efficient fin array or chiller source.

In reality, all sinks, regardless of type, be they convection cooled finned devices or copper tubed modern jobs, are "conduction cooling elements" from the POV of the heat source. THAT is the device that needs to have it being bled off as fast as it is being created via dissipation.

SO the FIRST thing it needs is a mass of a determined size that has fast conduction properties.

Then, the bleeder mechanism of choice weighs in. This is why many newer sinks for CPUs have been a copper slug, press fitted into an Aluminum finned array. I have also seen, and collected discarded solid copper sinks.

So, if the finned sink likes the fast conduction slug interface to the heat source AND the finned array, then the INSIDE of the box having a good, fast conduction mass in it to make up for the issue the thin wall would cause is the right way to conduct the heat to the outer sinking mass, and subsequent bleeding (sinking) mechanism (fins, more mass, etc).

I have one here.

It is an inch and a quarter by an inch and an eight solid Copper slug, surrounded by the best Aluminum fin array I have seen in a while.

The first AMD cpus that came out running very hot, and if the sink was not intimately mated the CPU would fry and take out the whole MOBO with it.

More word salad

and surface quality

Of course it does. Good heat transfer, from semiconductors on one side and to the box on the other, needs flat surfaces.

We all know you're dumber than a stump, DimBulb. You don't have to prove it daily.

You are full of s*it.

The term refers to surface index, not flatness, idiot.

Note also that I made the requisite that the box be bonded to the spreader by silver filled thermal epoxy. Flatness would also not be an issue in such a case. Not that you could understand that fact.

Most if not all die cast boxes have a fairly poor flatness anyway, and that is especially true about the internal surfaces. But I wouldn't expect a retarded f*ck like you that spend his time deriding others information by posting bullshit to have any grasp of that tid bit.

And finally, dumbfuck, his "polished aluminum" would degrade the flatness as well. Of course I would not expect a twit like you to have grasp of the difference between the flatness of a machined or precision surface ground face, and one that was polished by a retard just like you with an abrasive belt and hand pressure.

Then, there is that "polish" term. I call polished Aluminum a mirror finish.

An idiot like you likely thinks that "polished" means what the dopes down at the metal house send you after it goes through their "timesaver".

Yet another stupid post by the Larkin dumbfuck.

What's a surface index?

Of course it would. Silver filled epoxy is still mostly epoxy, and doesn't conduct heat very well. Even diamond filled epoxy doesn't conduct heat very well.

I posted that fact here some time back. Guess you missed it.

John

And you have a serious scat fetish.

John

Looks like Johnny Bright isn't so bright after all.

You previously spouted "word salad" in another post, but the salad is in your brain. It is Dumb Boy Salad, and you specialize in it.

I knew what surface index was back in the early 70's at 10 years old.

Do you even know the difference between a #3 and a #8 polish?

I mean you already mistook surface quality for surface planarity, and they are two entirely different animals.
