"When it becomes difficult to see whether or not you have a component at the pick position"....

They had to redesign tape feeders and the tape peelback to accomodate these. Pretty insane. I soldered some 0201 bypass caps digikey mistakenly shipping me once but haven't tried 01005.

Damn.

personally, eeeeeeek

professionally, yayyyy more microscope sales.

I've soldered 01005 sans microscope with a tweezer before. Not really something I intend to do again.

About miniature components in general... (I have almost no experience with tiny smd...)

What about resistance on the leads/traces ? does a tiny cap have lower-than-expected performance because it has considerable resistance on it's leads/traces ?

Is there a table/sheet/rule where I can know about the resistances appearing on each size of smd ?

01005 is 8mil wide, the same as many small PCB traces, so I doubt it's much worse than the trace running to it. Not sure the exact dimensions of 008004. Obviously you won't be using these for critical high speed decoupling caps, but they're not exactly molecular.

Step 1: Squeeze on some solder paste.
Step 2: Sprinkle on an assortment of 008004 resistors
Step 3: Bake @ 240degrees for 300 seconds.
Step 4: Trim excess ingredients.
Step 5: Enjoy delicious electronics.

Definitely insane size for the experimenter...

Even with high magnification microscope and holding tools for placement, it's Star-Trek auto assembly stuff;
personally, I am to old to play with this size or any SMD... eyes and hand shake don't help; I'm sticking to
through-hole, for my old age to grave. $:=\$

Yeah, that's a given. I do 0603 all the time, but my rule is that if it's indistinguishable from the dust on my bench, it is dust on my bench.

AlfBaz · « **Reply #9 on:** April 04, 2013, 02:27:11 pm »

I remember when I did my first board with 0603's everything looked huge in the cad software, then I ordered the parts and thought I had made a mistake! lucky I didn't get carried away and go 0402

Edit: for the record, wiki recons 01005 is .4mmx.2mm

YES !
More parts per square millimeter, high desnity interconnect, blind and buried vias , laserdrilling , plugged holes... Now pcb layout becomes interesting...

Fixed that for you.

01005 resistors are only 1/32W. What is an 008004? 1/64W? That's just nuts. I wonder if they just vaporize when they pop.

megahz · « **Reply #13 on:** April 04, 2013, 08:05:45 pm »

pshhhh I can solder that with my eyes closed

marshallh · « **Reply #14 on:** April 04, 2013, 08:06:55 pm »

In addition voltage derating for ceramic 008004's will probably be insane, even 0201s suffer a lot from that

Been there, done that.

I bet the first one to use these extensively in high volume will be Apple. They make tiny logic boards and often have crazy designs constrains just to bring you certain feature like being 23% thinner and 10% lighter. Or a longer lasting battery, something like that. But let's not turn this into a flame war.

c4757p · « **Reply #16 on:** April 05, 2013, 01:29:49 am »

Definitely in a cell phone first. Mine is about a year old and definitely has some SMD parts that would be best described as "powder".

lemmegraphdat · « **Reply #17 on:** April 05, 2013, 01:48:31 am »

The boards of today are shortly going to be the microchips of tomorrow.

nukie · « **Reply #18 on:** April 05, 2013, 04:18:53 am »

One more reason not to memorise resistor color bands.

c4757p · « **Reply #19 on:** April 05, 2013, 04:54:30 am »

Yes, because 008004 can be used on a breadboard.

AlfBaz · « **Reply #20 on:** April 05, 2013, 05:26:26 am »

These things are that small you'd be able to have the components mounted on midlayers, prepreg should be able to absorb the height fluctuations

Radio-Shack (and/or Dick Smith in Australia) will release "My Home Wafer Fab", with a shout out to pioneer Jeri Ellsworth

Imagine if we can print resistors/capacitors/transistors directly onto a substrate using something similar to an inkjet printer.

No more soldering needed except as interconnects between boards. Even that could be done over fiber optics using printed organic leds and sensors.
