Soldered 0805 vs 0603 vs 0402 vs 0201 vs 01005 vs 008004 today :)

[alexg]

Hi All, just wanted to share cool experiment I did today, I soldered few capacitors today on same board starting from 0805 down to 008004, all the way down to 0201 is super easy, at 01005 that's where fun begins but still quite possible even with 10x magnification. I may do this over again in couple weeks because pads for 008004 came a bit too small so part offsets when solder start flowing, which is fine but not aesthetically what I wanted
I used to think 0603 is small

[Rerouter]

This will make a great reference picture aswell for many future readers, its sometimes hard to grasp just how small they are,

I've had to do 01005 by eye before, It wasn't hard, but it wasn't easy, 008004 by eye is something i hope i never have to do.

[Fred27]

008004? WTF? You just made that up.

[alexg]

Its ridiculously small, this image from net shows them lined up on the match head and smallest one there is 01005, so 008004 is twice smaller that that if you put it on your finer tip it will sink between fingerprint lines

0201= 0603 metric. 01005=0402 metric...what could possibly go wrong....?
Guess why I have a strip of 01005 resistors in an unopened Digikey bag my drawer... ( it does occasionally come in handy when someone comments that 0402's are tiny.)

Incidentally....
2512, 2010, 1206, 0603, 0402, 0201, 01005...  all 2:1 aspect ratio
so why 0805 and not 0804? Anyone know?

Im so shaky, i only work with 1609 or 1610...

I suspect it is arbitrary. Fun Question though.....

  Thanks for the image alexg. I just started doing some SMD work with 0402 (imperial 1.0 x 0.5mm) and the thought of using these smaller sizes is horrific 

[Brumby]

I've hand soldered down to 0603 without too much difficulty. 0402 was fun, though - but I think that was more from the fact I was doing it on matrix board and the pads were a little too widely spaced.

I have some 0201 resistors I bought cheap off eBay for challenging myself.  Haven't opened them yet.

[amyk]

You've beat this guy who hand-soldered 01005 a few years ago: http://donkey.vernier.se/~ghlargh/01005/index.html

[Neganur]

I used to think 0201 was quite doable but that was before my eyes got bad almost everything has to happen under the microscope nowadays.

Anything smaller than that risks getting damaged by tweezers too easily imo! Rather just reflow that stuff.

[timgiles]

Amazing. Not sure I could do that (hand solder) below 0402 - not even sure I could place those two smaller components and reflow it!

Gonna have to buy some of them to show my colleagues - they thought 0201 was crazy.

[KL27x]

I wonder what the vacuum pickup needles look like for those things. The tweezers look gigantic.

[Brumby]

At that size, almost anything can cause component movement problems.

Six molecules of condensed rosin vapour on the tip of the tweezers is enough to act like a blob of Blu-tack.  (Perhaps a slight over-exaggeration.)

That's no exaggeration at all 

 SMD components sticking to the tweezers is the bane of my life.

Just curious: What size of tip, and what diameter of solder did you use? Did you add extra flux?

[Psi]

When 1206/0805 surface mount PCBs first started to appear the old 'gray beards' complained that 'electronics just wasn't serviceable any more'

Now we have 008004 and people are still trying to solder it at home

Cleaning frequently with acetone will improve matters IME (stuff from a paint store/dept., not nail polish remover). 

[NivagSwerdna]

As a hobbyist I think 0603 is the sweet spot... that size is where components get super cheap so you can order 100s rather than 10s.

And it is the smallest size with size code on resistors.

Thanks Yes I tend to use Isopropyl but it's just a PITA having to do it all the time.

A quick question - your tweezers are non-magnetic, right?

(if it isn't - get a set which is  )


Edit - changed 1=1 to 1=0; (if it isn't - get a set which isn't  )

[analogo]

I used to think 0603 is small

Metric 0603 is small! 

[Mr. Scram]

Hol' up. There are two 0603s, depending on which side of the pond you are?

[Rerouter]

even on the metric side of the pond, i would imagine 0603 would mainly be thought of as the imperial footprint.
