substrate

It's damn near impossible to get a decent definition for "substrate",

so this little teeny blog entry will prolly say nothing and go nowhere.

It's the circuit board with no traces (electrical paths) and no components glued on.
But my definition sounds so elementary, so third-grade-ish.

I (being very unsure of myself generally) question my definition.
Beeesides...
You've got "Multi-layer" Printed circuit boards,

metal and non-conductive material sandwiched tightly together.

So what is "Substrate"?
OK nevermind, for now.
I could paste a hundred definitions, each more convoluted than the last,

and it would not become clearer.

Google's front Page says "Glass substrates" are coming....

yedda-bleh-bleh-bleh (drilling glass is hard)

as an Audience member whispering while the sales rep is speaking (strictly a no-no)
I wonder what the hell "organic" substrate" is anyway.
Dead-corpses stuck together? nono.
"Plastic"?

freaking overused word "Organic" (whut? O, I'll shut up now)

The salesmanship changes drastically and the technicalese, depending upon your googling technique.

Organic materials in manufactured products,

Organic materials in *electronics*

Suddenly we're all postgraduate physicists

Fucket, *I* will surmise and guess and seek out.

Yeah!!

Now...(ahem) what changed?

That was rhetorical mostly, because this is no book nor sales brochure.

Now all's I gotta do is drop a biggie wrench into this, "Organic substrate"

WE all know that upper-crust military computer chips insist upon "ceramic"
and cheap-ass regular-type radio-shack chips are "Plastic", substitute your own word here.
HEAT is mostly the reason.
It's been this way FOREVER.

Anyway.....
