What is a KA?

[Don Lancaster]

Just got in an obviously super expensive precision step reference.
A Veeco 138-369.

The step height is 9.315 KA.
Not the sort of thing you would trip over.

What is a KA compared to, say, a micrometer?

I'd hazard a guess that KA is kilo-angstrom, where 1 angstrom = 1e-10
meters

So 1 KA would be 1e3 x 1e-10 = 1e-7 meters or 0.1 micron

Not so small when you realize we're now making 0.04 micron
feature-size CMOS.

I love to cook with wine. Sometimes I even put it in the food.

Assuming its a linear measure, as used in wavelength measurement, its
probably a kilo Angstrom.

1 A = 1e-10 m
1 kA = 1e-7 m = 0.1 microns

Kilo-angstrom, i.e. 0.1 um.

Kilo-angstrom, i.e. 0.1 um.

In which case, it should be written "kA".

Nah, that's like having an EU quality control spec for mercury-lead
alloy dental fillings. Not that the SI police aren't just as mean as
the ROHS ones, it's just that they can't put people in gulags. ;(

I use "K" on schematics instead of "k" for readability. I get a
ration of #$%& here every time I post one

I thought the Kuga would be some kind of lady who likes younger guys,
but it's actually quite a nice wee SUV (despite the electronics
crapping out on me).

For some reason, "compose O A" doesn't work here, although dumpkeys says
it should.

The non-doers are called customers or users. They have a right to
complain if they can't decode your parts values.

Ready to switch to 1K2 ohms instead of 1,200 ohms or 1.2K ohms?

I assume you mean "1K2" instead of "1200" (who uses that nomenclature?) or
"1.2K".

No, but I have switched from squiggly lines to rectangles. Don't like 'em
(but they are easier to draw with PDF editing programs ;-).
