I am an aerospace trainer in J-STD-001 Space Addendum who formerly taught 8739.3. He is soldering to NASA-STD-8739.3 (Soldered Electrical Connections). Google the standard which was not cancelled at the date he performed this demo on a J-hook terminal connection. To ensure high reliability interconnections NASA mandates pre-tinning and solder removal by wicking. This removes oxidation, ionic and organic residues/contaminants that will affect solderability compromising solder joint wetting, integrity and high-reliability of functionality due to the extreme thermal cyclic vibrations associated with launch and re-entry known as an uncommonly harsh environment.
Nice job John.
Why are gloves not used when handling components?
Hi. I'm wondering why the NASA-STD-8739.3 was cancelled and is there a new standard for it?
Meets ECSS-Q-ST-70-08c-The manual soldering of high-reliability electrical connections-2009 too. I guess they are much the same
That's why the U.S. never made it to the moon. LOL
NASA: now cut and clean your sodder, don't burn it off!
Me lighting a cigarette with my iron: what the eff is this guy doing?
You do a really great job of teaching these skills. Thank you for making this available for those of us who want to learn how to do this right.
Quality makes the difference! It costs a bit more but you get what you pay for. Thanks. Btw. Twenty years ago I've learned this the same way.
Thanks for making these videos :) It's useful to see how the 'pros' do things :)
The most entertaining part of this video was at 8.27 when another machine started up,a fret saw I think and the guy holding the camera sighed and almost growled . Must be a shared workshop at the Asylum. However it was a tutorial and I did learn a couple of things. How to make a solder bridge and never to make a video in a shared shop. Thank you for the upload.
Are these guys the same team that did the Space Shuttle hydrogen tank sensor connector bypass fix? One of the funniest space program fixes of all time.
Great post.
Beautiful
Cable moves at 9:42 even though you stated otherwise in the end.
Where did you get the spring wire holder? Or did you make it?
I do this kind of soldering every day would be an idea to close the hooks a little tighter and rounder works better in my opinion then solder it
excelant bravo
الكثير من الملمارسين مهنة تلحيم الإليكتوني لا يفهمون كل هادا ضياع الوقت ، هادا العمل بي التدريج تلحيم الإليكتوني هو عبارة علي دقة عالية الجودة ،لي ضمان عمر أكثر مما تتصور من مقاومة التلحيم و صلابته ،نعم هادا هو عمل الإحترافية في التلحيم الإليكتوني ، لأن مجال التلحيم الإليكتوني وصل الي الفضاء و الي أبعد قاع في البحر ، إدا لا مجال لي إرتكاب الأخطاء في هادا المجال بي الدات خاصة التلحيم الإليكتوني ، أحسنت سيدي الخبير
Is this for demonstration purposes or do all expert solder techs have a spotter?
Where would one find springs for holding cable cores? I've also seen two part phenolic block with slots for different diameter cores or holes for different diameter contact pins but can't see them at rs, farnell etc. Anyone know the manufacturer(s)?.
any two pieces put in a vise would work as for the spring, masking tape works best
Avionics at a work bench I am guessing. Try using this method on 300+ terminals inside an aircraft. Behind the instrument panel or in a radio rack! Not only is the space difficult but you can't take 9 mins a terminal.
I work under EASA not FAA so not aware of your standards, but can you use solder with flux in?
underwaterdick rosin core solder has a relatively short Shelf life
Is there smoke and fume absorber? The Right hand is not positioned properly and shaking. Soldering iron should have more wattage.
wow.. methodical
Can anyone tell me what Soldering vise this is? I can not find it anywhere.
Panavise
ive watched a few of ur videos and it woould be crazy and crazy tedious and long to clean, flux , and everything else u do besides tinning and soldering, especially for large products ,and like SMD stuff
Probably nice to have lots of molten tin running down the wire. Very professional.
You mean flux? You are watching aerospace grade work, the highest professional level. The excess is necessary to ensure full dispersion and penetration of the solder into the joint for high reliability.
~12 steps only to place the wire?
hahahahahahaha
wires should be formed off the hook by wrapping around round nosed pliers masking tape over the tips of the pliers will prevent lead damage
Well, this is like NASA grade quality control. I'm sure many of these practices don't apply to some dudes trying to fix their stereo.
theryaner no shit.....
But kif I'm pactised in soldering to WCSS.NASA.IPC then it's just as quick to repair my stereo to the same standards and practice joint and station hygiene
theryaner but what will happen if i use these practices to fix my stereo?
Of course not, but anything you learn here can be applied to anything you solder, to whatever quality level you choose, with predictable results.
@@radius.indrawan then your stereo's audio quality will be astronomically insane.
Precision is not enough description here! But what is the purpose of the J-Hook connection? According to Wranglerstar the soldered joint is 'stronger than the wire' - hmmm. One wonders.
This is a really old video, and the result seems quite high quality, but i do have a question - Is this level of detail actually really necessary? From a practical standpoint, what advantages does that level of effort bring beyond standard good practices?
none. this is just to have it standardised.
Reliability. If you have a connection that's going to have high current through it, a poor job will result in reduced transfer region as all the current will travel through the bits without oxidation. This generates heat at the connection point, further encouraging oxidation, and the cycle could eventually result in the wire burning up and disconnecting. This happens all the time with household appliances.
this is for really important stuff like airplanes or rockets.
Usually projects are huge, costing anywhere from a few thousand to billions of dollars. There will always be some connections that will need soldering by hand. To get rid of any chance of a failed connection, you gotta do this, or even more in order to get the desired level of quality. If it fails, it cost you the time, money, resources and morale of the entire project team. So you do things in a way where they never fail. Or don't do at all
Why the need for the phenolic board in the steps?
+R5H4D0W Protect the workpiece / insulation from swarf and residue from the vice grips. Protect the vice grips from heat.
It's called Panavise, they have a great range of vies grips and holders.
Este instructor certificado de la nasa, nos presenta una simple soldadura de 2 cables como si fuera ciencia espacial.
Because everything in space is critical.
Yo solo queria soldar un simple cable y llegue aqui porque la porqueria no se pega
10 pasos para pocisionar el alambre. Nomas.
Ah yes kimwipes, the govt brand of paper towels. And they clean your glasses and your car windows too.
If this is expert level i wonder what reballing or soldering one tsop-56 chip is to you
+Tiago Oliveira Hmm, I've had a look at your soldering methods on your channel., specifically "How to downgrade a PS3 Slim, Teensy 2.0++ PART 3 (Soldering preparation)". You have the incorrect size of solder wire.Your tip is filthy. Your joints aren't wetted. You paint the solder on.You have dirt and residue in the joints. You don't clean up.Part 4 you lay exposed conductive parts across pcb traces. You think your work would be acceptable on critical ground segment equipment, let alone on a spacecraft? It would cost hundreds of millions to plan and execute a servicing mission .Learn to do basic joint proficiently before you go near circuit boards let alone publish 'instructional videos on TH-cam..
+Frank E Davidson Let me tell you something Frank,that video is intended for BEGINNERS why da fq would i want to explain every detail to an average person that just wants to downgrade a ps3 and will throw the iron away when finished?? ITS A PS3 NOT A SPACESHIP the soldering is not permanent it only needs to be OK to work not PERFECT,and the video that you watched is an outdated version where i used my old iron, but again i ask you if this is expert level how you classify soldering a tsop-56 chip? this super over the top for the average consumer it took me i think 15 or 30min to solder 45 wires for you is about 9hours, but this should not be labeled as EXPERT LEVEL if you think doing what you did in the video is super hard i feel sorry for you, i really do
Why 'teach' beginners poor soldering techniques? Perhaps they don't want to go as far as downgrading their item to toast.
You confuse expertise with complexity or pin configuration.One either has expertise at a task or one doesn't, the other task has no relevance. If a TSOP IC is soldered to poor standards it certainly wouldn't be 'expert' by any stretch of the word. This isn't just for beginners it's for anyone open to learn to solder to a proficient level or review their current practises. This might include repair techs wishing to go into the aerospace / military sectors and curious to see the standards in practice. It's good to see videos like this and ones from the IPC which promulgate good practice because there are so many videos from bish bash bosh bodgers passing on their skills. Don't feel sorry for me, if I had to go on tools, I can solder to ECSS standards and have loads of offers of work. What's super over the top about board and tip hygiene principles (OK, except for the cost of the branded low lint wipes to the consumer sector)? What does "Da fq" mean?
Well i don't care if you have alot of offers, my video is not intended to teach the correct way to solder, it's just for the regular person that wants do downgrade with no complications, the soldering that i did was not poorly made it only needs to be OK all the wires will be removed after 10 or 15min so WHATS THE POINT of having every thing clean and perfect?, if you are working for nasa good for you, and strong connections need to be made i understand, but don't tell me that i did my work wrong becouse i did not, do you really think that a normal person who just want to downgrade a console whants to learn all the soldering standards? No! Thats is not an expert its basic it's a good soldering but anyone can do it like you did in the video so it is not expert level, i don't see nothing confusing on my videos if you don't understand is becouse you don't want to understand, Read this out loud "Da Fq" maybe you will understand what it means...
+Tiago Oliveira You called him out, he returned the favor. What the hell do you expect?
looks like over kill but if its for a flying aircraft better safe than sorry. jim he said the pliers had no teeth
edmundo oliver also imagine how many soldering joints are on aircraft. Excess solder builds up in weight. There are thousands of solder joints
It seems like overkill but unfortunately these methods are built on the failures of the past. Aerospace environments are some of the harshest known to man, and they can cause failures that can kill the crew if these standards are not maintained.
I thought I heard a "woops"!
so much foreplay..
soldering level...not china!!
How long he had that iron on the hook, all that solder ran down into your clamp.
messy level... Expert?
When are they gonna show some "expert" level Soldering techniques? I didn't really see any.
Jesus Christ!! No wonder spacecraft cost so much! These guys take four hours to do what real-world technicians do in two minutes!
Thats because this method is part of the standard for the highest quality joint possible. These types of joints are used in life dependent situations and have much longer expected lifespans than what a tech can do in 2 mins. If they were connecting wires for household applications, they wouldn't use this. This is for systems that CANNOT fail without dire consequences.
This is for electronics that need to survive the trauma of launch and space. How many of your "real world" technicians are building equipment that need to handle such harsh environments?
He's training. Training always takes longer.
😂😂😂
Lol
zZZZZzzZzZZZ
At 12 minutes per terminal this must be government work. And why is TH-cam dropping this in my feed 9 years later???????
I am glad I am not an expert as I don’t have someone to read the instructions to me and I can’t take 12 minutes per terminal. 😂
Tis man is a typical armchair expert, who has never made a decent soldered join in real life while repairing or building piece of electronic. This method is a textbook example , almost with self parody approach in unnecessary steps created by experts departed from reality.

Vladimir Stefanovic buddy, he is soldering to MIL spec, which is an extremely stringent standard required to minimize failure on mission critical equipment. If your looking to fix hobbyist electronics you could use electrical tape if you'd like.
Fully agree, this is no where near the level of quality used at most avionics shops.
@@pageau1987 The guys I work with do.. Truly an art to behold when you see this level of work done very fast. Shoot, I saw a few things I would have called non-target.. acceptable but non-target. but then again, some of the birds can have lifespans half a decade and live in some of the worst environments for electronics -- where failures can mean certain deaths of the crew and whom ever the bird lands on... you don't want the outcome of the investigation to be your solder joint...
@@joshuaguthrie8067 I meant we do much higher quality
Defect in all classes for tinning the j connector before soldering to it. Dont follow this videos if you want to know the right way to do this.
Yar0niX You are mistaken. I am an aerospace trainer in J-STD-001 Space Addendum who formerly taught 8739.3. He is soldering to NASA-STD-8739.3 (Soldered Electrical Connections).

a "pro" with a crappy weller amateur soldering station... LOL...
weller were good irons when this video was made.
Don`t ever do piece work - you won`t earn any money!
