1. What temperature do I use for my hot air rework station?
2. How do I start troubleshooting a problem?

We’re going to try to address these things in our online courses.  In the meantime, we have two course available now, which cover the absolute basics of how the iPhone logic board works all the way up to the intricacies of doing a touch IC repair on an iPhone 6 plus.

The first course in our series is called iPhone Logic Board Repair: The Basics.

The online course lasts 1- hour and it’s broken down into 6 different sections:

1. Introduction
2. The Logic Board
3. The Tools
4. Defects
5. Troubleshooting
6. Repair

In the “Logic Board” section, you’ll learn about how the logic board operates and the building blocks of the logic board.  In the “Tools” section, you’ll learn about everything related to the tools and equipment required for microsoldering, like zxw tools dongle and schematics and physical tools.  In the “Defects” section, you’ll learn about the most common reasons for defects to the logic board.  In the “Troubleshooting” section, you’ll learn about some real life examples on how to diagnose a problem.  And finally, in the “Repair” section, we’ll give you examples of how the thought process behind a water damaged phone and touch screen problems.

All in all, this course is mainly for those just getting started and don’t really know where to start.  The hour long course will give you general ideas on what to expect.

In our second course of the the series, labeled iPhone Logic Board Repair: Advanced.  We cover the three most common iPhone microsoldering repairs: No Backlight, Touch IC Disease and Charging problems.

The course is broken down in the three sections.  Each section details how the circuit works, the common points of failure, and then we dive into step-by-step instructions on how to troubleshoot and repair the failure.  These are extensively tested and defined solutions to the most common iPhone problems.  We’ve literally fixed hundreds and hundreds of these devices with the methods described in the course.

These are just the first two courses in our series.  We’re aiming for a complete course teaching everything from how to get started to fixing the hardest microsoldering repairs, like BGA problems.

Update! We no longer sell the individual courses.  We only sell The Basics and The Full Curriculum courses.  See the below link for more information.

The problem seems to lie in the NFC flex.  This is the plate that is usually connected and screwed in last after a screen repair.  It looks like this:

If we drill down a little more closely near the connector on this plate, we can see that there is a little tiny resistor embedded in the plate.

I’m not exactly sure why Samsung decided to place this resistor on the NFC flex, but this little thing serves a big purpose, which is to tell the phone when it’s too hot to charge.  Without the NFC flex connected to the phone, the phone will display the temperature too low warning.

The actual problem doesn’t usually have anything to do with this NFC flex.  The actual problem is the connector on the logic board in which this NFC flex connects to.

This is what the connector looks like on the logic board.  It’s located slight below and to the left of the battery connector.  You’ll know exactly where it is because it’s where the NFC flex connector connects to.

In the blurry image above, if you look at the bottom row of pins, you can see the gold contacts showing through the black plastic connector.  In the top row, you can’t see the pins sticking out and if you look closely, you’ll see that the connector is actually bowed outwards.  The connector in this shape usually results in the Note 10 temperature too low warning.

This is usually due to repeated attempts at connecting this NFC flex using too much force.  I must admit that after trying to connect this flex myself, I found it very difficult to put back on without using my microscope.  I’ll just chalk it up to a poor design by Samsung.

the fix for this problem is to use some very fine tweezers to bend the pins and connector back into shape so that the pins are showing beyond the plastic again.

You’ll need some very pointy tweezers.  Probably better to have two of them, so that you don’t break the connector.  Using one tweezer, you want to push inwards from the outside and then using the other tweezers, you want to push the bottom outside of the connector, which should result in the middle row of the pins showing past the plastic again.  You can watch a video of the process here:

If you don’t feel comfortable repairing this yourself, then feel free to request a quote and we can fix it for you.

iPhone X Logic Board Repair

The iPhone X logic board is a whole new animal. All of the iPhone logic boards prior to the iPhone X were one piece:The iPhone X logic board on the other hand is made up of two pieces held together by a middle connector ring, which is soldered to both separate logic boards.

The top logic board contains the CPU, display system, cameras, and logic for most of the accessories.  The bottom logic board contains the logic for the touch system, wifi, and cell service.

It’s obvious that Apple’s design was to save space within the iPhone housing, so that they could make the battery capacity bigger, since the battery takes up more than half of the real estate in the housing.

The one thing that has been causing most of the logic board problems on the different iPhones is the fact that housing bends most of the time.  The logic board is held into place with screws tightened to the housing, so any bending of the housing also causes bending to the logic board.

When the bending of the logic board occurs in the iPhone X, the top logic board separates from the bottom logic board causing no touch, no cell service, and/or no wifi problems:

The picture above is an image of the two logic boards and the middle connector ring.  Notice that the three pieces are separated from each other near the middle.  This means that the solder joints have disconnected from each other.

As you can see in the picture below, when the two logic boards have disconnected from the middle ring, you’ll often see missing pads.  In this case, there are many missing pads.

All of the black/brown spots are supposed to be silver and shiny like the other ones on each side.  There are hundreds of these pads, which connect the two logic boards.In order to fix the logic board, one would need to desolder the two logic boards along with the middle ring, fix the missing pads by running jumpers for each necessary pad, THEN put everything back together and hope it works.  As you can imagine, repairing the iPhone X may not be the most feasible thing to do. Especially when a lot of these pads run under other chips:

Unfortunately, there is no easy way to run a jumper under a chip to a missing pad.  One option would be to transfer the wifi chip (UWLAN_W) and the baseband chip (cell service) to another donor logic board, but doing that itself is no easy task.  And the last thing is, how could anyone warranty this type of repair?  If a repaired iPhone X comes back in as a warranty repair, it would most likely take a few hours to try to fix again.  With all things considered, I don’t see an easy way to repair the iPhone X.  However, data recovery is a different story.

iPhone X Data Recovery

The bad thing about the iPhone X is that repairing the logic board is going to be very difficult.  The good thing is that the success rate for data recovery should be pretty good.  The reason being, the iPhone will still boot with another bottom logic board from another iPhone X.  So, the typical data recovery will go as follows:

1. Disassemble the logic board.
2. Separate the top logic board from the middle ring and bottom logic board.
3. Place a known good bottom logic board/middle ring into an iPhone X jig (e.g. iSocket, JC TX-BAS) and then attach the top logic board.
4. Boot up the phone with a known good screen, charge port, and battery.
5. Do a backup into iTunes.

This is what an iPhone X jig looks like:

This is a setup of the actual jig hooked up to our donor iPhone X logic board with battery, screen and charge port.

Using a different bottom logic board prevents the wifi and cell service to work since the original cell service and wifi chips have to be used in order for them to work, which is why you see the triangle icon at the top right and no wifi networks to connect to.

Conclusion

Unlike previous versions of the iPhone, the path to data recovery on the iPhone X is actually easier than repairing the logic board.  In terms of repair, at this point, I don’t see a feasible solution to repairing the iPhone X due to the amount of time that it would take to diagnose and repair.  And I don’t think anyone would logically want to warranty any type of repair on the iPhone X.

If you would like to your data recovered on the iPhone X, then please contact us using the request a quote form.   If you want your iPhone X repaired, then you can still contact us, but understand that data is the only thing that we would be able to guarantee.

With devices getting smaller and smaller and more and more expensive, sometimes fixing these devices is more beneficial than replacing them.  Devices like Amazon’s Kindle Fire that sometimes cost less than $50 are usually not worth the time to fix, but iPhones and iPads that cost up to $1,000 with a broken $2 chip or connector makes sense to fix instead of buying a new one.

Also, Apple does not offer micro soldering as a repair option.  They have aggressive upgrade programs, almost always recommending that customers upgrade to a new phone or tablet instead of repairing them.  Most of the times, these micro soldering repairs are easily repairable with the proper tools and equipment.

Let’s look at an iphone logic board zoomed in about 200x:

Now imagine trying to place a small bead of solder on one of those small components.  Nearly impossible without the proper micro soldering tools and equipment, like a microscope, hot air rework station and a soldering station.  Also required are the proper parts, supplies, and components.

Gone are the days of big CRT TVs and VHS recorders with many moving parts.  These days, devices fit in your pocket and there are zero moving parts inside of the device.
