Order some .1 uf capacitors and check that they are 0603 size NOT 0402 size.

You don't like soldering dust specks? ;)
Second note: don't sneeze when handling smt parts. Order more bits than you need!
3rd note: Don't breath in too heavily when handling smt parts....

I swear, these things evaporate!
They seem to respond well to frying, but getting them in place is quite a project.
I think they do Brownian motion.

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here.
No guarantees, but if we don't report problems they won't get much of a chance to be fixed! Details/discussions at link given just above.

Come on, we know you're from the Windy City, close the lab door!
My apartment IS a bit drafty. I have blankets hung over the windows during cold weather.
Whizzzzz there went another one!
Did you know Chicago's nickname, "The windy city" has nothing to do with weather? Though it does rather describe the weather.
"The windy city" has nothing to do with weather?
Does it then refers to the inhabitants suffering from flautulence?
Dang it... made me spew my beer over the keyboard!
It IS Friday!
In the case of chip capacitors, I'm thinking, "bigger is better." I don't find 0603 size parts hard to deal with. Yet.
I didn't look close enough at the order page to see what size they were.
Maybe if I'd learn to make solder stencils the 0402 parts might be easier. Na.. Set these aside and get some bigger ones next order. Fortunately, they're cheap.
I agree. 0603 are what I usually use.
I do occasionally use some 0402. I made a little tool to hold the chip while I hit it with a blob of solder on my iron. I also use a tool to hold the 0603 chips.
I've also occasionally soldered them with hot air. One problem with hot air is I don't know when the solder melts so I can stop the hot air. Supposedly I should be able to see when the solder melts, but I guess my eyes aren't good enough.
6th note: make sur teh point ofd the tweezers are right or you will have jumping components all the time.
ow and note 7
keep your desk clean. when components jump you might find them back on your desk. if there are other components you can again only bin them as you dont know the right component anymore.
we use 0603 mainstream, occasional 0402 and even 0201. the last are fun to solder :)
0201 capacitors are hard do solder if you have wire bond areas 200Âµm from the solder pads.
Steve get a bottle of compressed nitrogen and pipe it into Your hot air system. Hit the chips with hot nitrogen.
But don't 0201 parts become a wave instead of a particle when you look at them?
01005 are my favorite...
If you ever watch a pick and place machine flying through a stack of 0402 (or smaller) parts, you'll understand why assembly houses default to at least 10% overages on small SMT parts.
The moniker "Windy City" was used to describe Chicago politicians when the city hosted the World's Fair -- Apparently they bragged/talked to much. Who ever heard of a politician talking too much?
Science is not consensus. Science is numbers.
Right. Has to do with politics.
Maybe I'll start designing with bigger Rs and Cs. Surface mount brick, anyone?
Lay a large sheet of white paper over your work area before starting the job. "Lost" smd parts are easier to see against a white background if they land there.
You can also pick up the page and pour the parts back into a dish for easier collection.
