Microsoldering 101: iPad Mini Backlight Filter Replacement
Вставка
- Опубліковано 5 жов 2024
- Today we’re tackling a repair Jessa sees frequently: replacing the backlight filter on an iPad Mini. This part is smaller than a grain of rice and according to Jessa, not a great place for a beginner to start. So that’s why we have Kyle stepping in for his very first attempt at a microsoldering repair.

this video had me transfixed, on how you would actually complete it.. and you did. great video and enormous patients.
Well done you did well on your first try I have done this type of repair for a while (years) I now have to use a stereo microscope as things have got so small well done Jessa for being so patient and a good teacher I look forward to more videos on here and on ipadrehab
this is great. next level repairs! I've been wanting to get into these kind of repairs but it's really difficult having no electrical engineering background to even know where to start so thanks for starting this series ifixit :)
Kyle is great at communicating what he is doing. I know this video came out years ago but if he has his own program I would like to see it.
I love the mistakes. it helps to feel like a classroom. there is no way someone would get it perfect first try. and even after practice its a hard one. Great video.
Thank You, Thank You! Awesome work Jessa! Kudos. I have had an interest in microsoldering for quite some time, but have had difficulty finding good information. You have opened new doors for me, and I am grateful for you sharing your knowledge. Many blessings!
I waited so long videos like these, thank you!!!
+Luca Pertile yes me to, it looks like easy to do but is very dificult and thansk for make this , becaus eall make video as they do it as simple work but ii is not and this is very good on this
Nicely produced! Thanks for the sharing!
i actually see these size of parts in real life.. i did a laptop repair, and there were these kind of resistors on it that were this small.. i saw it, but couldnt replace it.. but maybee now i can..
That is the great video I have ever seen before.
Every time I watch microsoldering videos on this channel, they pull the pads.
great job for a first-timer! respect!
Videos like these are so interesting! Thank you
Louis rossmn typically takes a wire thats way too long, then solders it in each place and cuts the excess so its easier to work with
great tutorial very easy to follow and understand what your saying as you explain really well .
thank you
Im just getting in to the micro soldering so what kind of magnification instrument should i buy and what price range ? i know there are cheap £100 video microscopes but are the useable? or is it top notch straight away :) keep up the good work . very interesting and informative ... high fives
don't throw the small component away. Maybe it can still be repaired. Micromicromicrosoldering.
you are very good on doing this
could you piggy back component. solder replacement to failed component to form bypass ?
This is excellent I have tried but got scared hahaha yes! because of the Pad but I am going to revisit that ipad and going to give it another bash. Thank you very much
Message for the guy with glasses : PLEASE IMPROVE YOUR SOCIAL ETIQUETTE AND REFRAIN FROM CUTTING PEOPLE OFF MID-SENTENCE. It's rude and very irritating. There I said it.
True
OK, I know all about resistors, capacitors, inductors, diodes etc and I can generally recognise their SMD versions, but what is a microfilter? I presume it's just a microscopic version of the ferrite interference filters you often get on power leads, but if so, why should it be so prone to burning out? Surely the wire running through the ferrite can't be much thinner than the PCB trace Kyle had to attach his wire to.
+pleriche yes, SMD filters are ferrite interference filters. The conductive path inside the filter is thinner, I think, than the traces. The filter design is to convert RF energy into heat, which is my guess why they can't withstand sudden shorts to ground. The conductive core simply melts and bulges out of the component like a pin prick of solder, breaking continuity. Great question!
Would it be feasible to make the connection with a big blob of solder instead of a copper wire?
Wow, that is really really tiny.
Great UL. Thanxx!
Hi experts! I have a Samsung galaxy (GT-S7580) that has a problem with its backlightning, such that the brightness of it cannot be controlled anymore. I narrowed it down to a faulty component or connection on the motherboard as I had another working S7580 to test it with. But there ends my knowledge of electronics. Any help in identifying the possible faulty component or to troubleshoot this further would be most appreciated. Any sites or forums that could help me out with this? Thank you!
You never said what the fried component actually was. The "filter" had to be a coil because you could reestablish continuity across the two points and complete the circuit and it work without actual replacement. Since that coil (filter) was open, why not dead bug the new device on top of the old (open) one after cleaning up the parts pads, saving the original pad and trace the part has welded itself to. If you've got plenty of space, why not use it.
Do you mean piggy back? I use to do that all the time with an open component, where I would just leave the old component in untouched and just apply the new device onto the legs of the old device. This way you are not destroying the circuit board.
I'm just looking at this cause I found it interesting, but I'll never do anything with this size of components. But I am going to swap a potentiometer in an old headphone amp cause it's noisy and cleaning it doesn't fix it. I have pretty much zero soldering experience, but I've watched a lot of videos about it :P Watching completely ruin that headphone amp :P
I heard "You know" like 100x
TechnoGenuine lol I thought the same thing. Take a shot every time you hear “you know” - Cheers
My brother changed his Iphone batteryu, he told me he could not access to any system update then and was obliged to put back the old battery until getting the waanted updates. Final comment " I HATE APPLE" ;)
What temperature are you setting the machines too? I tried using hot air and even at 375c it's not doing much
Make certain your using lots of flux . If you still have issues add some low melt solder like Quick Chip to mix in with the leaded solder. Nobody can tell you a heat measurement simply because everyones hot air station is different.
where do u buy the components? and how do u identify them?
I can do this! Ive done similar with only a magnifying glass to see it. how do i make this mt lifes work? how do i make this make money!
Are you guys giving credit to where you looked it from or you guys actually figured schematics?? whitesomtesla? but hey it is great video. great details and video. +1
+atinder2006 I love Filip and the work he does for the cell phone repair community. I remember sending him a message years ago now telling him that I found the retina mini backlight filter when the device was first released way before the retina mini schematic was released. Of course once he first saw a retina board he would also be able to figure out the backlight circuit, it is very straightforward and similar in all iDevices. I am always a fan of his work, but really want people to learn to look at the schematics and actually figure out their own solutions!
what is the model of iron soldering ?
I wonder what would happen if you connected two pads with a nicrom wire trace and sent power through it.... would it be considered a micro wench and as it shrinks pull one pad out of place lol
I didn't intend to watch porn this morning. Great video! I adore this site. 😎
He such a geek and it's cute
como se llama este cautin de doble punta donde lo puedo comprar gracias
great!!!
amazing. loved it!
"examining the booger" yes!!
BRAVO!!! remember it is all in " how you hold your mouth "
i am speech less. I trying to gather the cash to make the purchase on those machines. but i have the soul to make it.
Use hot air!!!
I don't understand how you can do repair without ESD safe procedures? You are touching the board with your bare hands, if this is a real consumer product why there are no mat under the device to protect it from scratches on this flat table??
When the fix is done you'll deliver the repaired product full of finger marks on the board and screen??
Don't get me wrong but I did this for over 10 years in Japan and Europe and there, they follow standards you guys aren't. By the way, where is your ESD safe jackets??
coisasnatv I have repaired thousands of iPhone and iPads and have never had a problem with ESD. So from a practical standpoint, it just isn't necessary for this kind of work, the components arent that sensitive. There is nothing wrong with fingerprints on a board and back housing, the iPad back casing is meant to be handled with your bare hands and laid on tables. The LCD is a tester LCD so fingerprints are not an issue. We ask people to keep their actual LCD, digitizer and hardware at home and just send us the board for repair. In practice, once a digitizer--especially a low quality one--is installed, then it isn't practical to re-install it. The effort to remove the old adhesive from the digitizer to reuses it, and the risk that the digitizer flex had a crease in it from the original install makes the best option to install a new digitizer at the end of the board repair. When doing a screen replacement job, wearing gloves is a must to avoid fingerprints on the LCD and digitizer. On this one, the customer did sent the bad digitizer that they had tried to install, so it was a good example to illustrate the problem that low quality digitizers have on screen repair for iPad mini.
+iPad Rehab Taking the "practical standpoint" aside this is not professional, I don't know your credentials but we follow standards to repair any electronics like IPC-7711 and IPC-7721A.
It might not be practical to you but it show your professionalism, it show you care, it show you have knowledge, this add value to your work. Do you like to buy a brand new product full of finger prints?
Nobody like it! Why?
Because we follow standards when we assemble this products, when you apply this principle to a repaired product you show a differential, you call attention to a work well done by a professional and not by an amateur.
Think about it, take this as a positive feedback ;)
Have a good one!
Nah--I take it as bs. And to answer your question, if I bought a brand new device that had fingerprints on a logic board inside the device, I really couldn't care less.
+coisasnatv ESD Safe procedures is for noob. if i break a new component then replace it!
+coisasnatv The repair is being done on a ESD mat. It's the huge white thing taking up half the table.

deberian ser mas concretos, hablan mucho y trabajan poco
El problema es que hablan inglés, y vos hablás español. Hablan de mucha información importante. Me parece que te cuesta entender lo que se habla.
Muchos videos de esto se concentran en hacer el trabajo. Lo que termina pasando es que los que miran el vídeo no entienden lo que pasa y no aprenden. Jessa le explica a Kyle todo lo que se hace de manera que permite que todos puedan seguir. Aprendí mucho mirando este vídeo igual que mirando los otros.
Si te cuesta entender lo que dicen, es mejor que pongas los subtítulos automáticos y busques las palabras las que no entiendas en Google.
Can you please not do these great videos with the train expert kid from Polar Express???
