The best soldering "how to" I have watched ..Wish I would have seen this when I was first learning..

[@sethreign8103]

You should watch Louis Rossmann's videos

[@seanmohrhoff502]

This was an excellent tutorial. Up until now, I've only been shown "Here's your iron, here's two wires. Wrap them around each other. Now melt the solder onto the twisted wires. Wrap in tape. Done." I've never seen flux, tin or a desoldering braid used before. It never occurred to me that the copper braid just sucks up melted solder like a paper towel. Thankfully I've never had cause to solder something like a USB port or the like, so I've never manage to embarrass myself on this sort of repair. Thanks and keep them coming!

[@OhYaseen]

AMAZING! Constantly asking the student questions forces the student to become the teacher. Thus information is retained faster and more effectively than any other technique. GREAT teacher!!!

[@JamieKitchens6]

Very informative. I have done microsolders out of necessity before, but I just played it by ear. This really sheds a new light on the whole process. Thank you Jessa and thank you iFixit. Keep up the good work.

[@cosmicallyderived]

Love Jessa's expertise and solid personality! Great combo, keep her posting.

[@spartan456]

This is an extremely useful video, and VERY informative. I've tried soldering USB charge ports in the past without a microscope and I can say with confidence that the microscope is a fantastic investment for improving quality of life. And really good tips with how to tack down the pins on the port. That's something I've been struggling with for awhile (mostly just because of solder bridges), but I never thought to take it one by one very quickly just to tack them and then clean them up later.

[@poket8095]

This is an amazing lecture! The best I have seen on the usb port replacing. Thanks a lot for your effort!

[@khurr]

Great class and awesome teacher...duplicate Jessa and put her in every high school...even love the mission of reducing waste in this world...thank you greatly for sharing!

[@yingchen6236]

Great great training material for soldering, from the basic physics to practical advises. Very much informative. Thank you for posting this.

[@Plan-C]

"You might have trouble with it because your tip is relatively small" LMFAO

[@giovannigarcia2947]

i love u

[@vikraal6974]

Creep

[@uandme7]

Thank You for this video! 3 days ago I managed to desolder broken micro USB port in my father's smartphone "ZTE Grand X In" and attach a new one! I did it with quite simple solder station (without HOT AIR) and Chip Quik - not Cheap at all ;) Everything without any microscope - only small (about 1 inch) 8x magnifying glass. I'm proud of myself and my father is happy again. Thanks - good job! :) Of course the new port was solder with a standard tin not Chip Quik..

[@rickymac54321]

I would of thrown that ZTE junk away and bought him a real phone.

[@albertoroura8027]

this is the best tutorial of how solder/desolder smd things on youtube! thank you for the lesson guys :)

[@imignap]

This is literally the only video you need to get going with PCB rework. Very nice! EDIT: maybe add some chipquik to the connector pads to not rip the pads.

[@isoertz]

That was sooo helpful. Next week i am going on a training and i already feel like i can do it myself lol. Thank you guys!

[@gbro8822]

Wow, I wish I had a Teacher like you. Great job.

[@gilclose5137]

As usual very informative, especially for the newby. Please keep up the good work, as i really enjoy watching profesionals at work

[@rudyw.5216]

excellent tutorial, very clear step by step instruction, now i can hopefully tackle my chip replacement and other micro jobs with confidence, thanks

[@jimvillanueva3039]

Excellent video. It was long but I watched the whole thing and loved absorbing some great technical knowledge!

[@kokkonosiko]

Thank you ipad rehab, you are the best teacher for all of us both newbies and pros!

[@conradgreenLA]

Incredibly informative video. Nice work Fixit n Jessica!

[@bigt3242]

Thanks for your patients and good teaching skills although I have been an engineer for a very long time I found some useful tips watching you very well done I will refer back to this clip when needed.

[@Darryl603]

When you are finished soldering, don't clean the tip before hanging up the iron. This will keep a layer of solder on the tip, and a barrier against oxidation. When you are ready to solder, clean the tip. : )

[@jeremyfine1464]

The Mini USB Type B Female 5 Pin PCB Mount just came adrift of my Seagate GoFlex adapter base. The electronix repair shop wanted about $40 USD to repair and for me to find & buy the part myself. Less than $2 for five from Amazon. After watching this I see why the repair guys get the big bucks. I won't be tackling this on my own. LOL. Jessa If I wanted to do this professionally you are the BEST teacher: imparting a real depth of understanding. I was transfixed.

[@lalmuanpuiamizo]

I really love the way you teach, please keep up. Let me add my technique replacing the connector. I cut the aluminium foil to cover the top and side portion, making kind of like a cap for the connector . Then hot air....

[@gr8safi1]

Jessica incredible tutorial. So informative and learned quite a bit. Many thanks, God bless.

[@JohnBakojohn]

Thank you Jessa and thank you ifixit. Greetings from Greece.

[@iserved8840]

Great video Ms. Jones is a great teacher, wish I had her for my electronics class !👍👍👍👍

[@1984juant]

BEST TUTORIAL IN KZbin FOR THIS👍

[@JessaJones]

+tecnico Thanks!

[@sethreign8103]

You should watch Louis Rossmann's videos

[@pincyberjedi]

Great video, thank you! I'd like to see also the desoldering/soldering with the hot air instead of the soldering iron. I loved the explanations!

[@2200char]

Is thats soldering station available for consumer purchase? It looks like a awesome station. These videos are some of the most interesting videos on youtube!

[@elieb7213]

Wow Jessa, you simply are the BEST!!!

[@xyloidify]

Well done, nice close ups, great teacher, thanks! Subscribed!

[@stevenlardes3540]

Amazing tutorial and also enjoying to watch. Good job 👍

[@yesno8204]

Love how this lady work.

[@jerrysmagic007]

She's awesome, learned a lot. I have been reluctant to trying micro soldering, this was a nice video.

[@DonaldJrRitz]

Mm is seems like a very informative video. You supply the information with reinforcement at a nice slow pace.

[@bearded1derr]

06:33 The juvenile in me was cracking up :-)

[@DT2012able]

Jessa - You are an excellent teacher.. It is fun and very educational .... Thank you for sharing it..

[@andypalm7061]

very good instruction here. This was fun.

[@dannyelpdyahoocombr]

Greetings from Brasil. you're a wonderfull teacher... thanks for this vídeo.

[@JamesMossR33]

Jessa's videos are compulsive viewing for me and I find them so interesting. All i've done is a bit of hobby project soldering, nothing as small as this though. With the right equipment I think I could (thanks to Jessa).

[@jaberjbaar]

who is this woman!? she knows everything!

[@curan]

Well, she does have PhD afterall :)

[@brentalous]

Excellent lesson. Can't wait to give it a try for myself

[@andrewwood5855]

Thanks great vid I order a new usb port less than 2 quid took it to a phone repair shop hour and a half and 20 quid all good great result , take somewhere you trust

[@floydloonie4880]

For $10.00 you can just buy a new micro USB board for the S3. I'm sure most people cannot soder with any degree of accuracy. You have great skill in delicate use of your hands, & it is wonderful for you to share this info. Thank you for sharing

[@KG-Handy-Store]

Hi, this is perfect tutorial thanks, i have a question, can you tell me which amscope do you have

[@brunolouis9707]

Very good video. I would like to know the temperature setting you use when using the soldering iron for: a. cleaning the solder using copper braid b. soldering the new usb port Thanks for replying

[@marcelozezan8625]

thanks... muchas Gracias desde Barcelona , España

[@rsyoung01]

Great video, thanks so much for posting!

[@boastyy]

Thanks for the video, very helpful learned a lot.

[@StephaneGarant]

Love the vid. I'd like to know what you are using to hold the pcb. What kind of vise is that?

[@Kawitamamayi]

Jessa is an excellent teacher!

[@JessaJones]

+Kawitamamayi thanks!

[@user-un9ll4wt7r]

You and Louis have made me much more interested in Learning soldering (which I am at this moment god awful at) I do however "repair" phones at work, but most work regarding that does not require such knowledge though it wouldn't hurt of course. Great teaching!

[@BadPete999]

I know it's an old video ! Very good tutorial and techniques your teaching ! question can you use no clean flux with regular led solder or just with only lead free solder ?? WHat brand of syringe flux works the best for you ! And what do you think about pencil bent chisel tips for fine pitch soldering ? some have a nice curve to get closer to very small capacitors and resistors !

[@ssouthwick123]

Hi Jessa! School's back in session and guess what - I just got a Samsung s3 with a bad charging port (along with 2 more toilet iphones which I'm really not having much luck with). Anyway, this video is perfect and just what I need since I didn't get to the charge port replacement in class. I'll let you know how I make out.

[@BigFolks916]

Great teacher...very helpful....thanks

[@procekim]

thanks a lot for this video. I watched all and 1.07 I checked the port to realise that it is not damaged only loosed. So i reordered in 2 minutes and now it is like new.

[@alphadragos]

Add more flux! :))) This lession is very helpfull.A great teacher results a great job .Thanks a lot for your vid.I wish you two all the best.

[@kevinconrad6709]

Great video. Thanks!

[@nonyourbuz5805]

Thanks for sharing this Knowledge...

[@atomikbbt]

I learned a lot of things

[@IsaacOLEG]

Hello I wantedf to thank you for that very instructive video. Allowed me to have my first success doing similar job (with card much degraded, I had to use a mini wire to reconnect it, hopefully only for 5V that time, so it was easier ). THank you then !

[@iphixationmetro9581]

awsome video- so detailed!!!!

[@mmenjic]

Bro you really are the rock star and are my idol, you are seeing absence of the trace, not the trace 😂😂😂😂😂😂😂

[@kieronalder9898]

most detailed video have seen on soldering charger port. ☺

[@KevinBritain]

Loving these vids..

[@JohnSmith-ws7fq]

Great tutorial, merci!

[@leogariba]

Nice teacher! Congrats!

[@niketurban.5569]

really liked this video, would you consider doing a Power IC repair for a Samsung phone next

[@brunolouis9707]

Nice Video. What temperature to use with the wire braid?

[@sshaikh3878]

Wow! its an amazing tutorial. Thx

[@Unrealdruiddd]

This is the best tutorial on the internet... Hello iFixit, the usb port on Moto G4 XT1625 is impossible to solder with an iron (no matter how fine the tip) as the pins are hidden behind the ground shield. I want to use solder paste and heat gun to solder it in place. Do you have any videos using solder paste to solder inaccessible components? Thanks a lot!

[@CranKBec]

That woman has a lot of experience! Thank you.

[@mohamnazeerhm2019]

BEST TUTORIAL IN YOU TUBE FOR THIS I LIKE

[@libenasukro]

"What do you think...." about me asking "what do you think" too many times? You're the expert. I am not here to hear what I think. YOU know the answer. I want to hear it instead of a question. Other than those distractions, I found this to be absolutely excellent. Thank you for the knowledge. Oh,, one question which maybe you answer later: If you use hot air, will the solder braid work or do you need the pressure of the iron to soak it up? And don't ask me what do I think!

[@buildstoys]

What do you think?

[@mouslimrevolution1]

thank you very interesting really good teacher i'm waiting for other video repair :)))))

[@robertcochran7103]

I'm deaf and I cannot get captions on this video. Can you please provide captions?

[@int16_t]

REALLY?? you are deaf?

[@SianaGearz]

I can hear pretty well. If they allowed community captions, i could help with the captions, maybe translate them to a few languages too.

[@fares3651]

30% Hakko ad.. 60% blabla 10% soldering

[@ertpecsertpecs]

My reply is for Harie Amjari not the other ppl in this thread that don't have their head squarely up their own asshole

[@freeuser8748]

Very helpful. Thank you.

[@yeshua4590]

Excellent teacher

[@yeshua4590]

Great teacher and student.

[@pearlmax]

Tune into the next episode where the man teaches the woman how to cook a lasagna.

[@elsayedhassan7455]

Great job.

[@gerff01]

I love seeing the "new guy" approach a solder joint on a connector like that, from the side he already soldered, knocking the one he just finished loose again...lol. I always have bets on how long it will take them to figure it out.

[@deapthynka1]

Great tutorial

[@benbenz1229]

Sure would like to see pace equipment in use

[@pakistani3931]

good job

[@angelisone]

Taking classes from ATG wasn't cheap but was worth it for me. ATG suggests to buy the Hakko FM-206 STA and I got it for a little over $2,100.00. I am able to repair camera's hdmi and usb. When I needed help ATG has email/phone supports.

[@maynardholmes8870]

What microscope are you using and what's a good scope for a trucker looking to get into this field

[@MrSpatsirk]

Thank you very much!!!

[@danielalburo3136]

I learned alot thank u so much

[@MajestX23]

I realy like this Vid. Thanks a lot... Great explanation .... best Zoom-Pictures.... By the way... i search for the right professional title for this kind of work. Where can i learn those pro-techniques?

[@Arek_R.]

That's a very nice holder, I manage to found it on google graphics, it's Hakko C1390C, but like $100 >.

[@full95one]

I was excited and enjoyed watching, unfortunately I didn't have any of this gear. I ended up just wedging a thin strip of plastic packaging between the board and the port it make the connection 😐. It works but it would of really been cool to say I soldered it.

[@fatboislim1902]

do they have a video on fixing those micro pins, like bridging one if it has broken?

[@mekamek891]

Woah. How have I never seen this person before. I seen Louis Rossman videos enough to have missed a person like this.

[@george54351]

Tip of the day:Always work next to your mama and have a dozen of appropriate tweezers for any type of connector available in the entire universe.Very nice and useful video if i had ever solder anything in my life then i could learn a lot.

[@mattfirm0909]

what are the mini hot tweezers model # you are using I have a hakko fx 951 but would like to get some of these.

[@zerorisers1160]

I recondition my tip my using one of those spongy sanding blocks. takes all oxidation off in one swipe then I apply solder. works fairly well without having to buy any special product.

[@vulgartech9192]

@42:00 I would have used a solder sucker to save wicking. 20 years ago the "third hand" technique was putting the solder in your mouth and just leaning into what your soldering. Nowadays I just tin the trace pads well and use solder paste for the anchor pads and just hot air the whole thing, sometimes anchoring the new part with an alligator clip.

[@rohanboswell5408]

hay jesa i'm in love with you, am working on a launch master 431 diagnostic scanner, it seems to have corrosion on one of the female connectors what do u recomend to prevent it from recurring

[@TheOriginalEviltech]

I don't tin the pads first. After i clean them i put the part on and solder them on. That insures the pins are as close as possible to the copper trace. If i bridge them i use used braid so it doesn't suck all the solder off, but leave just enough to provide a solid joint.

[@mrfrog8502]

I agree. i do the same. I know this ment to be tutorial for begginers but I don't understand reason behing few techniques used by her including removing solder with wick side ways and tinning pads.Each to their own I guess.
