What temperature / air flow did you use?

[@giovanniaaron974]

Hi friend. You have a solution for a logic board Acer Iconia Tab A510? The logic board not working.

[@duongquan11]

Very good video Sir, but can you more clear and details on how to dip some rosin with soldering iron to smoke the logic board? Do we need to put rosin on the logic board and use soldering iron on top ? Thank you and waiting to hear from you

[@rewatechnology2008]

Dip some rosin on the top of soldering iron, then place it above the logic board with a distance of 1-2mm.

[@tony_zen]

i like all you have tool... nice

[@perceive8159]

When looking at the cutter mounted in the spindle, it is not running true , actually it is running way off centre line, is the cutter collet broken? For sure something is not correct in the cutter, spindle mounting?

[@DINKINCORPORATED]

hello sir i got an iphone SE that wont charge after water damaged! iv removed the shields and cleaned with the unltrasonic machine ! the little resistors next to the battery connector seems gone! should i get these resistors? or replace the u2 is enough? hope you can help me!

[@rewatechnology2008]

Use copper wire to connect the FL2400. It would be better to find a local repair shop.

[@danielrock3119]

[@Demifiend911]

can you give me link for the repair pad you are using ? so i can put my microscope on it

[@wonseok_song]

What is a benefit of grinding PMIC rather than removing it with hot air? It seems risky.

[@gidbi]

benefit for them because some of us now will wantt amachine and this company make some benefit :D otherwise it is usless,, because in the reinstallation process they also use the 265 degree heat gun but it loos nice and new thats all ;)

[@gtrichard89]

i'm pretty sure there would be a lot of warranty going back to them if using low solder paste.

[@egidbotan]

I want to come and work with you

[@Traveltheworld4946]

How much fees to learn this thing?

[@emperadorsonn3575]

hello good morning my iPhone 6s+ is dead and I don't know the problem and it's not charging

[@raidshadowlegendsad8938]

What's the DIfference Between the PMIC and the Power IC (U4500/U2)?

[@rewatechnology2008]

For iPhone 5/5c/5s, it is named U2; for iPhone 6/6 plus, it is named U1700; for iPhone 6s/6s plus, it is named U4500.

[@raidshadowlegendsad8938]

REWA Technology my good sir, where can I find a iPhone 6s Baseband?

[@ahmedsaeed-yj6kj]

how did you know that the logic board comes with leak current as 900mA?

[@manishmohandas1075]

See the switch It's in Amps not in milli amps, You see lower side 0-100-200... that's in milli amps, but when they switch it to A, see the upper label of analogue meter there you can see 0.5, 1.0, 1.5, their reading is at 0.9A ofcourse its 900ma when we convert it

[@mrsemifixit]

Since most of us don't own a CNC machine. What's best method for removing PMIC without damage to CPU on other side?

[@johnbaker26]

tape a thick coin (i use one from Thailand) onto the CPU with kapton as a heat sink. Quickly remove the coin when your done(be careful will be damn hot). Try to keep your air down to a min temp. For my station I would use 360C for the PMIC. And most importantly (as you will fry CPU if you dont do this) is carefully check for shorts out of those low voltage/high amperage output lines from PMIC to CPU BEFORE you connect battery/cable.

[@mrsemifixit]

John Baker Thanks for replying. What size nozzle? Normally I use 4mm nozzle with 325c and air set to 6 (from a 1-8 scale). Should I use bigger nozzle, lower heat and air or same heat but lower air?

[@johnbaker26]

I use 2mm for something like PMIC. Lower air and try to keep it straight down on the chip. I have a bent nozzle you can see pic here tinypic.com/r/2lazodz/9 that makes it easier to keep it pointing down right at the chip and not blowing across. Its so easy to short this chip. A lot of VCC main and ground pad neighbors.

[@mrsemifixit]

John Baker You use a super small nozzle on it? Whys that. So you keep same temp but less air flow? What's a good time reference for when it should come off (so don't keep hot air on too long)

[@johnbaker26]

I don't know time, for me its all about feel. Watching the flux, caps around it start glowing, than if you notice any shakes from chip its time to lift it. Basic stuff I guess. I think the most likely failure with PMIC changing is shorting, I said ground earlier but that wasn't right. I meant VCC main ball shorts to one of those

[@digitaldigital3969]

WHAT PRODUCT DOES IT USE TO FIND A REGION THAT HEATS?

[@devanshtaneja5870]

digital digital steamed rosin to check if it melts. If it does the IC is overheating m

[@ctjk1982]

companies like this are the real eco-friendly unlike sending your apple device to apple in which the only thing they do is really just throw away the old device and try to give you a new one or try to get you to buy another device when companies like this fix the device so that there is less of a chance of the device going to a landfill which is good for the planet

[@tastytechaddictsmtb]

Apple actually repair your broken device and then send it back to the shops to sell them back to you are a referb phone. This is another one of their money making scams, they'll say your phone is unfixable and then take it in as a trade in for a new phone and then fix it and re sell it as a referb phone or as a replacement under warranty.

[@vincen.3590]

That is so true. They send these broken phones back to China and refurbish it. Apple is RIP off.

[@sams4976]

hello sir my iPhone is in endless restore loop can you help me get out of it thank you

[@lhk7006]

I thought a black iPhone has a black boot screen. Does the color change has something to do with the chip?

[@amalautpavathas6571]

verify back light ic and related parts

[@rewatechnology2008]

Our sample phone was usually bought from the market. The is a common problem for those faulty phones coming from recycling market.

[@itzzjok3rzz208]

L HK black iphones have a black boot screen, white iphones have a white screen, its pretty simple.

[@completemobilecare]

👌🏻👌🏻👌🏻

[@Lazier23]

Hi, my iphone 6s still won't turn on after changing the PMIC, why is that? Hope anyone can help me. Thanks.

[@rewatechnology2008]

@Zzul Hz Thanks for the comment. How about the boot current? Large current or low current? iPhone won't turn on might be caused by many reasons. Please make sure if it is the same situation as the video.

[@shahidkhan-mb8rm]

how to know if power ic or ram ic are dead ?

[@rewatechnology2008]

In this video, the logic board came with a heavy current. For this case, usually we will check the PMIC primarily.

[@yusrilraihan5365]

i'm you Fans from indonesia.. thanks for your video

[@rewatechnology2008]

The first, thanks. XD

[@mehmetali6934]

Please help me ghost touch fix ?

[@rewatechnology2008]

It would be better to replace the screen directly.

[@mrsomebody3984]

I Have The iphone 5s, but the screen won't turn on, after i replace the screen, charging port and also the battery, the phone doesn't have the home button after i break itself, i dont know how to do ?, before i replace the battery, the phone is getting warm and still not turning on ? what should i do ?

[@rewatechnology2008]

Did you also replace the home button?

[@completemobilecare]

🤘🤘🤘

[@user-bx3un6iu7e]

круто

[@Camilo19832001]

Uuhh.. can i send my phone so you can do upgrades on it?

[@rewatechnology2008]

So sorry that we do not offer individual services.

[@sharfazhameed6382]

That grinding machine sucks, I personally think it’s easier to remove the under fill and desolder the PMIC by hot air station.

[@azizbekyunusov9497]

😍😍😍😍👍👍👍👍👍

[@MasteringHow-To]

Connect the logic board with D.C. Power supply. Ohhhh ok. Hahah like who has these things laying around

[@knightphox]

General HowTo I do.

[@tastytechaddictsmtb]

virtually all repair shops do

[@keymatthew1]

I got one

[@vampirwrr]

i have one, and you can just use battery

[@HenningGu]

Those videos are for people who have a repair shop or are interested in opening one.

[@Andremzsptm]

although i love this videos, i cant see how this work can be profitable at all. why would anyone pay a lot to recovery an iPhone if you could just buy a new one with some hundreds of dollars? also the technical assistance would need to buy a lot of machines to make some of this work

[@mrsemifixit]

It's probably for data recovery

[@agarcia8800]

___ ____ also this is done in China repairs are cheap

[@phillipjames453]

My wife dropped her iphone 6 in water. She put it in rice overnight but did not shut it down. The next morning the iphone still works but we cannot shut it down. It stays on indefinitely. There is no response when pressing the side button. Does anyone have any suggestions how we can shutdown this iphone. Thank You in advance!

[@ratupmyass]

replace power button flex

[@ratupmyass]

alternatively search for 'shutdown' in the settings app

[@itzzjok3rzz208]

Phillip James the rice method isnt real i heard from many people, as it reaches cold temps it can make condensation. But about the home button, that sounds like a button problem, you might want to replace it, or try to possibly revive it? Good luck :)
