Really tiny SMD component

I ordered some samples of various components from a manufacturer and one was this schottky diode that is 1.1 x 0.7mm in size!  It's freaking tiny!

Check it out on this penny.  In the close-up, you can see Lincoln's head poking over the top of it:

That is crazy tiny! it's hard to imagine how even a pick-and-place machine would handle it.

the only thing i hate about SMD components is that it's a pain in the ass for a hobbyist :(

SMD's are OK once you have had some experiance in soldering them, but without the right tools they are a pain in the ass.

GaAs? I don't know... it's an SOD-523 case BAT54 schottky. Very small.

You could inhale some of those and you wouldn't even notice ;D

Haha, yeah, I actually lost the first one when I peeled back the plastic of the strip of them and it got flung into oblivion. For all I know, it's lodged in my brain somewhere now.

Just try soldering those 0400 surface mount devices. One breath and they are out of sight.

I used to work in a place where they did a lot of surface mount stuff.
I did diagnostics for 3D Labs graphics cards a few years ago, when they still
made things in the UK ;) A short while into production they decided they could get
an extra 10% speed from the geometry processor (which was a seperate chip
in those days.) by adding a resistor and a 4mm wire between a pin on a
flat pack surface mount chip and a pad on the circuit board. The legs on the chip
were around 0.5mm apart and had to be soldered by hand.
I'd quite often sneeze and half a dozen resistors would fly off the workbench,
never to be seen again. ::)

I really enjoyed the job though. I got to play with cutting edge technology.
State of the art graphics cards that retailed for £1700 ($3390)
It helps with my laser hobby, being able to work with tiny components and
experience in soldering them + ESD precautions.

My friends still don't understand me though. When I showed them a 20x dvd laser diode
and a few beam splitter cubes and were gobsmacked when they found out to get them
I had dismantled a brand new £23 dvd writer. ;D But for them £50 on mascara is good value for money.
For me. £10 on makeup and £40 on laser parts is good value for money.
