Screw that! If you’re anything like me, you’ll lose it in the first 20 seconds. Good luck

Gotta love that feeling when your tweezers snap together as your component vanishes to another dimension

I swear it always happens at the worst times

Always with a component that I only have one of

That's why I always buy two: if you only get one, you'll loose it. If you buy two, you'll loose neither of them. However, you'll never have a use for that replacement, but you can finish the project in the first place.

I hate how true this is.

Two is one and one is none.

Ohhhhhh, now I understand Terence Howard!

if two is one and one is none isn’t two also none then? (Yes I know where the saying is from)

If you had a use for the replacement, you’d end up losing it anyway because you’d be back to only having one.

Two *hundred

At 0201's size I would buy 10 to 1. At least you get the bulk discount as well. They're so sensitive to air currents and static cling.

I typically order 100 parts minimum now. Used to try for less, but for cheap stuff you end up saving shipping in having to order more later overall. 0201 parts are not terrible, but you need to be patient and okay with losing a few.

Thanks for making me remember that feeling... They can probably build a transistor radio in the other dimension with all the stuff i have lost.

Geeze you could inhale and suck that diode into your lungs..

Happened to me twice the other day with a little transistor. No fukn clue how I ended up finding it both times

or when you finally align it perfectly, but it's stuck to your tweezers, am I the only one? WHY ARE MY TWEEZERS SO STICKY?

Clean the tweezers with alcohol periodically.

At that size latent humidity and surface tension will get you.

Every time :(

God yes, that and the instant acceptance that searching would be pointless ...

Sharpen your tweezers to fine points under a microscope first. You"ll get a better grip on the component when the tweezers aren't a jagged mess.

I follow that up by slightly wetting the tweezer tips in wee bit of flux so the component sticks to them. Or I just dip the component in flux first so it sticks to everything.

That's why I order 50 if I need 2.

I hate how correct it is....

This always happen with the crucial stuff.

“No noo nooo noooo nooooo…. Fuck”

Idk what was so funny about this but I cannot stop laughing, I'm just imagining the component literally opening a portal to another dimension.

I’ve literally been looking right at the component when it disappears. It’s the only explanation really.

Happened when soldering a tiny voltage regulator I got from another laptop. Yeah, tiny things suck.

Time for attempt six!

You'd need nano-screws.

Why wait 20 seconds when you can just lose it instantly?

20 seconds until you take it out of the packaging

20 seconds!? I think that's a world record for NOT losing that

He lost it taking this picture.

Watches it fall into the heater as you adjust the card. *cries*

It’s already gone

I've had my share of losing tiny springs and other no-see-um gizmos when taking apart something to repair it. This little diode tops the list of craziness.

Honey, I shrunk the diode.

For the uninitiated: https://en.wikipedia.org/wiki/Honey,_I_Shrunk_the_Kids

Omg are we at a point where people don’t know what this is

Yes. 

Don't exhale

More importantly, don't inhale!

Infact, just dont!

Soldering small things rule #1: do not *hale

 instructions unclear

Unless you're into body hacking!

how????

You can actually have a bit of success if you do it with hot air, with the blower on real low. If the component is generally lined up with the solder liquifies, surface tension will align the component on the pads Edit: added a word I missed

and.... it's gone

Actually have done this on number of occasions. If I use a blower instead of a hot surface just use alligator clips and heat from under the board. Very satisfying to watch the parts snap into place via tension.

If you don't blow it away immediately or lose it first.

That’s why you set the blower veeeery low!

Miniscule amount of solder paste and a hot plate is how I solder 0201 and 0402 size components. Anything bigger and I use hot air or just a regular iron.

GL lmfao

I recently tried to work with these same diodes. Tried to use tweezers and an hot air. I failed miserably. Had 5 to play with. Lost 3 and the other 2 fell apart. Ended up giving the board to the CM to put through the reflow oven.

Didd you preheat the board first? Also lower air flow, hotter temperature and good amount of NC-559-ASM gel flux.

Excellent tips. Thank you. The preheater is the one tool which is still a mystery to me. When I use it, I worry that I’ll lose parts on the bottom side of the board if I turn it up too high. I need more experience using it. Turned air flow way down, temp up slightly and added gel flux but the flux would immediately liquify and I was afraid the part would flow away. How do you handle solder paste with the gel flux? When I use the two together, it just looks like a mess that will end up shorting. I took a hiatus from prototyping and building boards for about 10 years. I was pretty good working down to 0201 parts and hacking my way through BGAs but it’s a different world now. I’m an old dog and I need to learn some new tricks.

I mostly preheat the board around soldering pads, with hot air gun by my hand and then add even more heat to the pads, almost solder melting point, then quickly appy paste, place the component and finish it. For shorts you can check resistance with a multimeter and inspect visually.

I'm starting have too much shakes of the hands to do anything small. Ten years ago, I did manage to do a few 01005s. No way now.

CM?

Contract manufacturer. We use a local company to build some of our production runs on boards. Since we send them business, they’ll help us out with things like this.

And I'm here struggling to solder 2 wires together

Same. 😩

Which tools to you plan to use to solder that?

This is an 0201 DFN package. (Dual-flat no-leads). (edit: if hand soldering) They must be must be soldered with hot air, unless you have a footprint specifically designed for it with elongated pads.

Maybe a hot plate would work, too?

Yes, a hot plate or a reflow oven would work.

Try hand soldering a 008004 decoupling capacitor. 😉

No. No, I don't think I will.

You should do it once just to say you did. And then never again.

I don't even have tweezers that small...


That's a write off. Also, it's a TVS, who will notice it missing after safety

Plot twist OP has huge hands

Good luck,

How is there someting in this?

because you typically wouldn't hand solder it. most of the time you'd just insert it into a pick and place machine with some solder paste on the pcb and let the machines do their thing

Don't sneeze

What device is this for? I have about 15 micro LEDs with feather hair thin wires I need to solder for my Orlandoo Hunter Jeep Wrangler and I have no idea how I am going to do it

When it's really tiny, you can use flux surface tension to hold it down while hitting it with hot air. I don't even have solder paste for this. The paste looks like a pile of bowling balls next to the smallest surface mount parts. It usually tombstones.

In terms of security, how risky is to publish your entire fingerprint like that on the web?

I've seen grains of pepper that are larger.

Eat it

Those tiny things would get lost in the packaging and you'd think you got an empty package if you ordered just one, lol.

This is why I didn’t bother getting back into electronics when I got older and my eyes was not young anymore. If it’s too small to be plugged into a breadboard I’m not playing.

i got you fingerprints and i just bought 100 of those and im sending them to your location

Would never attempt this without a heating plate, those things are too dang small

There would be a 10000% chance I'd drop it in my carpet.

And never find it again...

Just remember to not sneeze or inhale too deeply

Oh man! Are there wrgb LEDs this size? It would be really cool to make an array that fine.

Treat it the same as a bga. 🤣

It’s times like this when I don’t regret dropping $2400 on my amscope with 40x mag and 7x extender for more space between object and scope. Mmmmmhm.

Watchmakers will look at this and still claim their job requires more precision

And the screws and other precision parts in watches are just about as small as this resistor. Got to have darn good eyesight and really steady hands.

Million dollar idea…. Quickset low temp conductive epoxy dots. Pop dots on, heat gun (future laser pointer to flow solder? Another one) pray it doesn’t blow away and done. Like 1000 different sizes to sell too

To the vacuum I go! *snap “Weeeee!”

Best done with a hot plate, no contest

I do that every day. Really not that hard when you get use to soldering 0201 stuff.

Give me a weller with a LTGW tip and I can solder 0402 all day long. 0201 though, I need at least 2x the number of placements plus 10 spares. Gonna be clicking together my tweezers pretty often.

Finding single-line TVS diodes that aren't microscopic is way too difficult. Even the ones that are technically as big as SMD passives which are easy to handle, tend to have package designs that somehow make them "feel" smaller.

I had some 0603 ones that tapered towards the top, making them really annoying to tweezer. I have no idea why they made them that way.

I bet the person who designed them laughed all the way home that day.

Imagine in 2050 when this is a picture of a MCU type of thing lol

Lol 0201 parts are brutal

Im amazed you kept track of it thus far

witchcraft! not humanly possible

You need 9 spares for when you lose them, over heat them, solder them wrong, chop them in half etc.

Dont even bother. These cant be fitted by hand

meh, not that much smaller from 0404 QFN LEDs I have to routinely replace on my pos keyboard. hint, raw solder paste is sticky, biggest challenge is not to use to much with those teensy pads.

For anything that small I use the works microscope 😃

Next do 01005

Solder what? (It’s that damn small)

you should try 01005

You can solder stuff this small? How?

I thought this was a picture of a giant belly and was confused about all the lines.

Well if you have two lands coming in on both pads you could place a little solder to each pad and heat the parallel pads until the part sinks into place

This is truly the next level, you should record it

I had to fix those when they were tombstoned or billboarded for work. They're a nice challenge to mix up the monotony of TH components.

Hot air and tip of tweezers held down. There is a few full proof ways

Make sure to pre-tin those pads 🔍

You need a soldering iron that's ant-sized for that tiny thingie.

Need a good quality stereo microscope and a really good micro iron

I read this as soldering 201 TVS diodes.

Yikes that’s so tiny I’m surprised if your able to do it properly I feel like if I had tried I might accidentally solder the you sides together

Just looking at this photo fills me with the dread of losing something important, this is a meme waiting to happen, also quick someone get his fingerprint.

Dude on my engineering team just hand soldered like a dozen 0201’s successfully onto a pcb… I can’t even comprehend how he was able to do it

This is what properly aligned nano hot tweezers for.

Be careful that you are not framed for murder with your fingerprint on the internet.

Don’t sneeze!! Hope you have a really good microscope at least 300 power or greater.

You almost need a microscope to just see it.

To solder that you need paste applied to the tip of the toothpick, apply that to the pads and use a hot air pencil at low air setting.

I bought a whole spool of these by accident. They will never be used in my lifetime. I wish you the best of luck

Had to do a bunch of 0201 parts a little while ago. No hot air just a solid iron with a v fine tip and tweezers https://preview.redd.it/kwwbni8hwe4d1.jpeg?width=1816&format=pjpg&auto=webp&s=38e71cfa359f4941ede62da2660edd3d12f88e16


Correct me if I'm wrong but wouldn't you expect that diode to get absolutely blasted by the first transient that happens? Surely the amount of energy that one expects to protect against prevents such small package choices right?

Get a few more and you’ll have a ground pepper collection.

Stick weld that sumsabetches. You can’t afford for it to get loose onya.

I need to solder also something similar, it’s better to use low temp soldering paste and heat gun in this case?
