I'm from South Africa we don't have something like this channel I'm learning everyday thank you.

You're really intelligent man...!!! You solve every problem with calm...I think so the your solution rate is 100 %

Thank you! Following your instructions, I've just reconnected Galaxy Tab Screen and it works again!

I'm a mechanical engineer primary but I enjoy fixing electronics, to solder or braze aluminium in mechanics you have to remove the oxide layer, and then keep oxygen away from the surface because even at 1000c it won't melt. I would apply normal flux paste to the area (to keep oxygen in the air away) then use stainless steel wire brush to scratch the surface oxide away under the paste (normal practice for soldering/brazing aluminium in metal work, I don't know why it has to be a stainless brush, this is just how I learnt). Then tin the area through the flux paste as normal to create a pad.

Thank you so much, I graduated with my AAT degree but always learning more and more. Your videos are amazing!

If you make scratches on the aluminum surface, solder wire can sit perfectly on this. I have solder many connections as this.. Thanks for your perfect lessons! I have learn many things from you!!

Soren,the auto parts store sells flat heating element to defrost wind screen. The adhesive for that is electrically conductive. Might be worth a try. Watching all of your vids, thanks for doing them. I worked developing analog and digital cell phone systems and in computer design creation and repair since 1980.

Hi there this is the full name of the adhesive - glue I use I recommend it is very good - you can buy on ebay - Silver Conductive 0.2ml 0.5ml Glue Wire Electrically Paste Adhesive PCB Repair

An awesome experience I gained today by the help of you sir! Thanks!

You can use special adhesive tin foil. The current passes the adhesive. Don't know where to buy this special kind but I have some in an external (Seagate) harddisk. It's used to ground (for some reason) the 3,5" HD device with the rest of the case. It's an inch wide.

Thank you, sir, I've had the same problem.It's thank God I solved it.Thank you so much. You helped me solve it.

Thank you teacher Sorin. You are the best... woooowww ... Brasilian here...

I fixed my tablet exactly the same way!!! Thank you so much !! :)

Hey man, thanks a lot ! You just saved my day (and the day of my little boy who's tablet just got back to life 😊)

Wow, the master tutorial is very good for beginners like me. certainly a lot of beginners like me who need this tutorial. beginners must try and make a tutorial like me ...

Maby not solder the connection but use glue instead and then specifycly silver glue this has a high amount of silver specifically for electronic connections to be fixed when soldering is not possible. I used it myself and i have to say it works amazingly well and the glue makes a great alternative for soldering!

I've soldered aluminum wires before but had to use plumbers flux and need to crank up the heat on the iron. I know it's not ideal for electronics but since it's not on the main board it shouldn't be an issue if you clean up the residue afterwards.

Very nice diagnosing! Would copper or alum foil tape solve the issue instead of soldering them?

I've soldered onto these aluminium tabs with 450°c iron with professional electrical 60/40 soldered but i have to do it first time its very hard to do after it gets gunked up with flux,you need to to use a cotton ear bud with acetone to remove the gunk an try again, I think it has something to do with a light oxidation even if the aluminium looks shiny.

Use good quality solder wire 60/40 is cheap and leaves a rough and coarse residue

That's great.You're so talented.I enjoyed watching your video.

I would try to apply a normal but strong shapping tape, and the to etablish contact with silver liquid painting for car glass defoger repair. I always keep it in case to repair tricky contacts on flat kapton cables or other, that helps a lot. That kind of silver varnish cost mad high but it even bear heavy current depending the number layers you apply on it

How about using an Aluminum, or copper conductive foil tape to splice the broken connection. The tapes come with conductive adhesive.

Almost as if it fell off the sofa a lot and the fractures started in the connections, very odd. I first thought the protection circuit in the battery was off because the battery voltage was too low. I wonder if aluminium solder exsists. Silver solder does exist, but thats not likely to work.

Why not use aluminium tape ? I did it in the past and it works. You can find the same thickness and width.

Forgive this old newb.. but maybe aluminum tape? or super glues with metal dust.. I do not know.. I am just stabbing in the dark.. I am waiting for the solar controllers .. Thanks Sorin.. I enjoy these sessions immensely.. carry on!

To solder broken battery terminals I use spot welder it works fine

thanks Boss u are just awesome. i admire your daily greetings "hi we are back.Today is tuesday I appreciate ur effort

Most likely this is not aluminum, but thin tin. Try to solder with ordinary rosin. Battery terminals take a lot of heat. Heat up the soldering iron harder.

to solder the battery pins I using a soldering acid or I scratch the pin and than I can solder on it and use copper bridge

Tinfoil and sticky tape does it every time for me

Yes that would work. But you need the type with conductive adhesive for example the conductive tape used to create shielding in the pick-up cavities of electric guitars.

RS etc. sell copper tape with conductive adhesive. Might do the job, resistance is low but don't know about how it would handle current or longevity.

If you scrat it a bit it will take solder but it s a balance with heating. I would go with spot welding

Mr. Sorin, you can use Vaseline - 100% petroleum cream to be used as flux to solder on aluminium.

I would use Copper Foil Tape with Conductive Adhesive.... Come on Sorin I thought you was going to fix the battery connections?????

It worked

Hello. “Alusol” is the name of the product that can solder aluminum without any oil layer. Is a solder made by loctite,but i hate to work with that... in romania you can found at TME.com, and is sold at one meter.

Has anybody tried using electrically conductive adhesive (such as the kind in automotive defrost grid repair kits)? May be easier to handle than solder but accomplished the same task.

Little help. When I charge the tablet it shows between 0.79 and 0.90A. On the measuring device, when the charger is on, the battery shows 4.25V, when the charger is removed, 2.25V. Otherwise, the tablet will not turn on. Black screen. I was checking the flat cable on the screen. Thank u.

I have a galaxy model SM-T585, i can play only when it charging, after i disconnect form charger, my tab always shutdown automatically without warning. Can you help me plz🙏

Yay! New video!

Where did you exactly connect the red and black probes when you did the battery test using voltage?

Hi Sorin! Are you sure there is aluminum? The shine looks like tin...

love u sorin...

maybe not use solder on that connection but instead try to crimp it .. you can make a crim connecter urself out of some old aluminium...or tin ... I did this to fix a brokean heater element in a toaster

No dodgy fix in this one Sorin come-on...lol.....jk.....thanks for sharing your methodology of how you broke-down finding this fault. Cheers!

02:31 and we haaaveee... :) Sorin u are a legend,i like your videos

Hi and thanks for sharing. Could you notice what is the temperature setting when you reflow a water defect for example or when you remove a chip on the mainboard with the airgun? I saw in an ils video you use 500°c, it is correct? Trying to solve an issue on my laptop, thank you!

Great vid

What if screen works but tablet is not charging only strobing on the edges. There is only charging sign (flash thunder) visible. cables inside are connected properly.

what about spotwelding ?

Thank you M.r

I have a Microsoft surface rt that doesnt light up the charger indicator. I did check and the voltage is present at the board. The 3 volt rail keeps oscilating up and down. Ever seen anything like that? Thank you

Maybe the solution for broken aluminum foil is Solderless Silver Conductive Wire Paste Glue!?

So when is the Electronics repair school channel party Sorin? The one where all subscribers are invited to your house for a barbecue weekend? 😃

You can try Dag conductive paint.

What i do is scratch the edges and make a hole on both pieces.Then i run a copper wire from both holes.Then i tight the wire and i put a little bit of solder just to keep it in place.Does the job for very long time. Try it and tell me.Another solution is placing one broken piece into another and make a fast shortcut with many amps so it can instantly solder the pieces together.

maybe rubber conducting connection..like to LCD screens fixed in place by the back cover...`?

I'm thinking why can't I aluminum tape to fix the broken connections? Have you ever used aluminum tape to join together a broken connection? Please let us know if you have or if you are goingvto try it.

Its been like a year or more since i have my tablet i loved the most working. it was a "SAMSUNG GALAXY TAB A 9.7 WHITE" I threw it out of anger and that's why it doesn't work anymore. Is there any way it can be fixed?

Good video

Hot Glue will do it

Im confused. Why would the tablet not work of power cable? I understand no battery power but can you use tablet off mains power. Thanks

My samsung tab 3 is not charging, and i cant power on. But when i tried to unplug the battery and plug it in back it just automatic goes on booting 2x showing samsung tab. Then it goes to black screen with no sign of power. What could be the problem sir?

does spot welder help in this situation? maybe, if you can could you please make one video how to make DIY spot welder. yes I know sarin can. :),

it's a sunlight problem , cloudy !! wants to start but can't and restart, not enough sun ...and bad mpt !! OK , I stop joking ,but for slodering alloys try low temperature bismuth alloy soldering , a bit like the one used on Pb free solder to get it to melt at low temp , many chinese sell this special soldering thing , melts at close to 300 centigrade and does solder alloy , I did 30 years ago to try solering aluminium under oil , never managed , and I was a professional for soledring , hope it helps you , young man :))

... i think changing teh battery is the best solution here: a very confined space, easily to make mistakes, and so on. but all the possible solutions for repairing are feasible, too, but no guarantee of a "final solve". if you plan to use the repaired battery for some amateur contraptions, ok, it's feasible, you can do it without fuss. 'cuz i'm a horribly lazy guy, who don't like to work every day at the same "fix"!... :)

hi from where we know the voltage and the amp must have a phone or tablet? thanks

hey uh i have same problem with my tablet do you repair these tablets of paid?

Great Guy.

Trying to solve an issue on an Acer Swift 5 (2018), it's difficult because MOSFET are controlled by specific chips after booting, primary 19.6vdc is OK on all chips and mosfet, solved an issue on 3.3VDC for accessories (only when SIO launch boot sequence, a shorted ceramic capacitor on the line). but I can't find the issue on VCore, 19.6vdc on ceramic capacitors but nothing on some outputs secondary voltages, gate is down (same during boot), now I could find 3.3VDC for accessories, 5VDC, 1VDC, 1.8VDC and 19VDC for battery charge )so battery is charging at this time, I'll try to add an 1VDC voltage (according schematics) after one of defective output coil and try to find heat element(s) on the line, because àt this moment I've got 0VDC bit not short with the ground.... 🤔🤞 Very difficult these new laptop, it will be complicated for repair... 😬😶🙃

Are you sure it's aluminium most batteries I've took apart are tin or something always been able to solder to them.

Easy solution is soldering wire for aluminium. This is the best solution for soldering enything.

Aliexpress sells conductive glue. Maybe good enough.

Search for "conductive cloth tape" on aliexpress. I would use that.

I think you can try aluminum sticky tape

Aluminium tape could be a possible solution?

it seems the customer showed another shop., the other guy has broken the connection when he tried to open back.

aluminum foyl and binders?

Hi sorrin you can just buy an aliminium sticker and join it very easy no?

Conductive tape could maybe work

More likely the battery was replaced with a new one and the tech at previous shop or the owner themselves mishandled it and applied pressure while holding it or placing it.
