Brilliant tutorial! Holds up extremely well almost a decade later. Thank you!

you can try using the what I like to call the "negative logic" tweezers, you know, this images-na.ssl-images-amazon.com/images/I/31MprBTs3fL._AC_SY400_.jpg

@@GrennKren LOL, it doesn't even get picked up by vacuum. small laptop screws do the same.
This video is 10 years old. They’re even smaller than that now.
that second diode you put on is a regular diode, but it called for a LED ,it was even printed that waythesymbol was even different
Thats almost exactly what I am making .
I forgot to set the volage output on a bec buck voltage regulator and a tiny smoke string came out of my 5.8ghz FPV diversity reciever .
My diodes came on a clip of the roll type you have . The strip has little pockets like mini butter tubs with a thin plastc film cover to peel back .
I just screwed a small vicein front of me on my desk and have a lamp on one of those 3 piece arm adjustable position desk lamos , and a microscope soldering goggles like jewlers lupe with flip up lenses . And a pointed soldering tip .
Thank you so much for making this video! I broke one off my esc key the day i opened my new pcb... :(
Saludos desde Venezuela 🇻🇪, tienes un mundo de diodos amigo,😳 mándame unos cuantos 🤣
Hi thank you it was really explanatory and helpfull
Love that old house neighborhood background though.
Solder paste is like magic :O.
Nice tutorial, good job, thanks for sharing
Jeezz you make it look so easy.
The moment I saw the diode, I could only think of my jittery hands...
+xXYannuschXx I just laughed at how tiny they were and thought 'nah'
I have a lot of difficulty with shaky hands too (I have a tremor disorder). Despite this I managed to solder 80 of these diodes onto an Ergodox PCB in one afternoon. It was not at all easy, but with some patience and determination it is definitely possible.
come on, this is huge diodes, what you think about SMD0402
Thanks for interesting movie. I learnt a lot.
pretty nice solder job
Nice job, well done... John :)
When trying to weld them, the silver square that is on the base came up, I tried to weld it again, but it no longer welds, and apparently that area seems to have burned, since it looks black, what can I do?
Turn the heat down . Maybe scratch or scrapethe solder resisting coating away with a sharp razorblade gently and stick a tinned jumper wire there by folding the tinned end over to double the wire like a stronger end to attach and try soldering the new diode to the othercend of the wire . Maybe mount it solid to not flop around with glue if it works .
Hi what is the paste you are using with the hot air ?
Good size board for some practice,everything is spread out.smd is hard enough to learn ,for us old school guys.
6:50 what temp and airflow you using?
I've been looking for a BVA diode for my gpu I haven't had any luck on sourcing any.
Hi What temperature was your iron set at? Thanks
I set one at 429 degrees farenheidt for 3mm diode and it did not do too bad . I think i used 60/40 flux core solder like from walmart . And a little watercolor paint brush for paste solder . A razor blade , a vice , a lamp , magnifying glasses at 5x . Looks like a 4mm pointed solder tip . Not sure
Do you mix solder flux or other fluid whit the solder past? Very good job!
Magic solder paste! :D
Thank you man!
Hey beans. What packaging is this? sod323?
Hey, great video! I was had a few questions. I received a hotswap board and it's missing a diode and dealing with the AliExpress vendor is not going so well. My friend helped me determine that it's probably a 0603 diode! I was wondering, when buying these diodes, do they have to be a specific type or is any 0603 fine?
Digi key brand comes in the mail 3 days in USA
I measured the diode with a micrometer and checked the specifications for the same similar type of diodes . Mine that burnt out was a peach colred . The new one is black .
Surface mount , led , glass diode , zenar diode , germanium diode , are search words , and there are 3 pin , 2 pin connection whatever the new one works fine . I saved $35 by fixing it .
😃
@@gregorydahl Oh great, thank you I'll look this up!
Where did you get those tweezers. They look pretty solid and steady.

I think after I saw you with the hot air gun I made a poor choice in tool selection for when I solder this smd cap back on my pcb
hello I have a 12 volt auto LED bulb that does not work knowing that in the circuit I have two or three SS34 diodes that burned, but the fan did not turn, do you think I need to change the diodes SS34 ?
Can i change smd led color Blue in my keyboard for RGB SMD? Is possible?
VERY BAD. Soldering iron WAY too large to make a proper SMD joint
Hello, What is the name of diode 2
For what are they used for?
Не используй мелкие сопла- даже при минимальном ветре поток сильный получается.
What size soldering tip do you use ?
Are you Canadian?
What size is the diode?
John Bäckstrand the diode is a third of piece rice
no way to know since the author never posted what model and package the diode is. but given the scale to the quarter's numbers estimate about 2mm by 1mm
Assuming that the PCB is intended for Cherry MX switches, you can get a good sense of the size by looking at the center mounting hole for the switch which is 4 mm. Then by using a screen capture and a graphics program you can determine the number of pixels for the hole diameter and the number of pixels for the length of the 2 diodes to get their relative sizes. I've done that, and it looks like the 1st diode is using the SOD-123 package and the second is using the SOD-323 package. Ignoring the leads and just looking at the epoxy body of the SOD-323 package, it has a length of about 1.7mm. The first diode is larger and it's length is about 2.7mm.
HOW TO PROVE.
Surface Mount Schottky Barrier Rectifier SS12
which camera you use to do that
Where can I find these smd diodes?
Digi key sells stuff .
That soldering paste looks like a dirty work since two drops unite as you heat it up. Is it safe to do like that? Isn't there a risk of a circuit?
a good part of solder paste is flux, once the solder begins to melt it will wick itself towards the pads and separate unless the amount of solder is way to much and it didn't appear so. once the flux was gone it looked ok
Surface tension and solder mask are your friends. As long as you don't have too much solder, the solder mask will repel the solder and the solder will just remain on the pads and component leads. In fact, if the hot air station isn't blowing too hard, surface tension will pull the component into alignment if it wasn't already properly positioned.
Take a look at ruclips.net/video/b9FC9fAlfQE/видео.html for a nice example of soldering a SMT IC. Pay close attention to how he fixes a solder bridge between two pins. And this video ruclips.net/video/8Q6YNmBKjiU/видео.html is a really nice demonstration of hand soldering different sizes of devices. Personally, I don't see how he managed to do the 01005 device. But it's definitely a nice demonstration on how surface tension helps.
I been using a smd practice board,even if you have all the right tools,this still very hard to do,this not for beginners.

How much is a reel.
Digi key sells online . A roll of 1000 might be $500 or less .
I bought 10 for 10 $ with shipping i think . Takes a 3 days i think you can buy 1
How do you know the specs of those diodes?
I had to go by size of the contacts spacing on the printed circuit board i was fixing .and measure with a micrometer and check the size of the new ones in the catalog amps volts size . It is an smd (surface mount diode) it is working now .
Thats a keyboard pcb :P
what ya making?
Those were keyboards.
Paano magtanggal ng smd fuse?

Couple of days ago I did 250 0.6 mm LED's with Iron and 0.8mm (0.032) soldier. No magnifier just by sight and some cheap crappy tweezers. I had three errors; 2 had bad connections and one I forgot to soldier altogether, so all considering I do not think I did to bad.
😃👍
muito bom o aprendizado valeu
Cheer buddy Thanks for the upload.
what is the part number of the diodes you are showing?
Hey weird question. I have a mini human spine made out of PVC it's about 20" tall.
All the spine parts slide and stack on top of a metal rod so they all have a hole in the middle to do so.
This leaves about 1.5mm of space in the hole through each of the 20 parts that comprise the human spine.
Should I just get one straight wire and small LED lights and solder them all onto the wire so it fits down the hole?
i don't know if this project is done already or not but that sounds awesome
Does isopropyl alcohol corrode the board?
Alcohol should not corrode the board so long as it is not diluted down with water. 90% isopropyl alcohol will evaporate a few seconds after it is applied.
