There is actually a major change about the iPhone 15 Pro that is "invisible", which is the redesign of its internal frame structure. In the latest video, the YouTube channel PBKreviews disassembled the Apple iPhone 15 Pro model. Today, PHONEFIX will lead you to explore the internal structure of iPhone 15 Pro.

Design structure

For years, smartphones have either opened from the front or the back. Apple finally solved this problem with the regular iPhone 14 in 2022, enabling the phone to open from the front and back. This huge upgrade allowed us to improve the iPhone's repairability score over previous models.

Apple has redesigned the middle frame structure of the iPhone 15 Pro to make it easier to replace the back glass. If you need to replace the back glass, you only need to heat the back plate, then pry open the glass on the back cover, and disconnect the flexible circuit board from the back of the circuit board. Cables, just replace it with new back glass.

USB-C

Apple has always been widely criticized for planning its own product design route, but convincing Apple to change its direction required tremendous pressure. It was not until the European Parliament mandated a unified interface that it was achieved.

In addition to the obvious compatibility benefits, the new USB-C port can deliver 4.5 watts of power to external devices. Compared with the previous Lightning mobile phone interface that could only output 0.3 watts, this is a 15-fold upgrade.

The A17 system-on-chip (SoC) adds a USB 3 controller, enabling USB 3.2 Gen 2 10 Gbps transfer efficiency. Because non-iPhone 15 Pro models inherit the older A16 Bionic, they only support USB 2 and are limited to the same transfer speeds as previous Lightning-powered devices.

Cell phone battery

The battery capacity of the iPhone 15 Pro is 3274 mAh, which is better than the 3200mA of the previous iPhone 14 Pro, an increase of about 2.3%. According to Apple’s official battery life data, the battery life of the two is the same, and the video playback time can be up to 23 seconds. Hour. Therefore, the actual experience of the increase in battery capacity is probably not strong.

Overall, battery capacity growth is weak. This is certainly not good news, as the A17 Pro is very power-hungry. There have been previous reports that the phone will get hot and continue to heat up, and the battery life will be shortened accordingly.

Brand new titanium case

The largest amount of metal in an iPhone is in the frame, so Apple turned to advanced metallurgy to save weight and gain some marketing points.

An interesting theory about weight reduction is that by taking the weight off the perimeter of the phone, it will feel easier to move around. The technical term for this is moment of inertia, or the force required to rotate the phone about its axis. The technical term for this is moment of inertia, which is the force required to rotate the phone on its axis. With less edge weight, the phone feels more nimble in your hand—like tucking its legs in when rotating. Compared with the actual weight reduction of 9%, the iPhone 15 Pro series will bring a greater "feeling" of being lighter.

Electronic components

Through the teardown, we can confirm that Apple is using Qualcomm's high-end Snapdragon X70 modem. According to Qualcomm, it is powered by artificial intelligence for beam management and antenna tuning.

The Apple A17 Pro six-core application processor comes with a six-core GPU that may sit under SK Hynix DDR5 memory.

Camera

The big camera upgrade this year is a "prism" periscope lens that boosts the iPhone's optical zoom from 2x to 5x. The Samsung Galaxy S23 Ultra technically beats this with 10x zoom, but the way Apple engineers achieved it is particularly interesting.

A physical challenge smartphone camera designers have struggled with is the thickness of the phone's lens system, and using a periscope allows the sensor to be slightly offset from the lens, thus reducing the thickness of the lens module.

About PHONEFIX

PHONEFIX is a large Chinese store selling tools and consumables for workshop and mobile equipment repair. Soldering stations, programmers, heaters, splitters and other tools on the official store page.

With the launch of the latest iPhone 15 series, people's attention will once again focus on Apple. There are many people using it, but as the use time increases, your iPhone will start to have problems, so how to solve it? Today, PHONEFIX will solve 6 common mobile phone repair problems for you.

1. Screen repair

iPhone screen repair is one of the most common reasons why people need iPhone repair. It is estimated that more than 50 million iPhone screens in the United States are broken each year. But what can you do if you break the screen?

Repairing a damaged screen is possible, but you have to assess the extent of the damage. If your screen is severely cracked, use clear tape to prevent more shards of glass from falling. You can also use a screen protector.

You can replace your phone's screen yourself, but you need to know how much it will cost and whether it's covered by a warranty. If you try to repair the original iPhone screen yourself, your Apple Care service may become invalid. You must purchase the right screen repair kit and follow the step-by-step guide carefully.

Professional iPhone screen repair can be cheaper and less risky.

2. Charging problem

If your iPhone won't charge, don't panic. Some simple solutions can solve this problem. First, try using another iPhone Lightning cable and plug to see if the problem is with your phone. Also, try another power outlet and check the iPhone battery health.

Also check the iPhone charging port. Sometimes, dirt, lint, and other debris can build up and prevent charging. Before cleaning the ports, turn off your iPhone. Use a toothpick to gently loosen and remove debris; never use metal in the charging port.

If you're still having charging issues, try hard resetting or restarting your iPhone. How to do this depends on your model. For example, older iPhones often require you to hold down the power button and the home button at the same time.

Newer models usually require you to hold down the power and volume buttons. However, check the instructions for your specific iPhone model. If you're still having problems, you'll need a professional iPhone repair.

3. Device unresponsive

There are several reasons why an iPhone becomes unresponsive, such as a failed upgrade or hardware issues. It may experience screen freeze or it may get stuck on the Apple logo. Black and white screens can also make iPhone users shudder.

You can try restarting or resetting your phone. You can also try charging your phone to rule out battery issues. You can also try restoring your iPhone to factory settings, but be aware that this will result in the loss of your data unless you use a recovery data service.

If your touch screen is unresponsive, check to make sure the screen is dry and clean. You can try to free up storage space and clear iPhone cache data.

4. iPhone accidentally got water in it

Remove the phone from the water as soon as possible. Turn off your phone and remove any phone cases. The longer your phone is on, the more damage can be done, so every second counts.

You can use a dry cloth to dry your iPhone. Also, remove the iPhone SIM card and tray so the water can escape. You can try the port and then put your iPhone in a dry and warm place.

Wait at least 48 hours before trying to turn your iPhone back on. It can be helpful to take your phone to an iPhone repair facility to have your iPhone checked before you try to turn it on.

5. iPhone runs slowly

iPhone performance naturally degrades over time. Sometimes a reboot is all that's needed. However, bloated software, full storage, and apps can slow down your iPhone.

Start by checking that your iPhone’s iOS settings are up to date and update all apps. Delete any apps you don't use. You can also free up storage space and turn off background app refresh settings.

If your phone restarts frequently, you can also try reinserting the SIM card. You can also try a factory reset. If you're still having problems, you'll need a professional iPhone repair.

6. Wi-Fi and Bluetooth issues

If your phone isn't connected to cellular data service or Wi-Fi, turn on airplane mode for about 30 seconds. It helps your iPhone forget to connect and reconnect. You can also go into network settings, select a Wi-Fi network, and then select Forget network.

If you still can't connect to your Wi-Fi network, try resetting your network settings. Go to Settings > General > Reset > Reset Network Settings. You can also try renewing your lease under Wi-Fi settings.

If you have trouble connecting to Bluetooth, check to see if Bluetooth is turned on. If the device isn't listed under "My Devices," make sure to select and pair the device you want to add. You can also delete all other Bluetooth devices because sometimes there are too many connections.

Also, check that your iOS software is up to date. Sometimes, it's worth simply restarting your iPhone. Restarting can refresh iPhone memory.

Article conclusion

If you're having trouble with your iPhone, don't panic. There are many iPhone repair solutions. You can try these solutions to help repair your iPhone, or you can ask us at PHONEFIX, and we will do our best to give you the most sincere help suggestions; however, if the problem persists, you should seek professional support.

When the logic board on your iMac , Macbook Pro, or Macbook Air fails, or if it has been liquid damaged, we can fix it!

Motherboards / logic boards are printed circuit boards which allow all components to communicate to each other. If one component fails usually the whole motherboard fails. Each component has a unique function to carry out.

A microscope is required to see the components in order to fault diagnose. Replacing the faulty components is not as easy it may sound because firstly, you have to know which IC or filter is faulty. To find the faulty part,  motherboard schematics are used. Once the faulty chip is identified, the next stage is to remove the faulty component and solder the new chip in its place.

This is much cheaper than spending hundreds of pounds on replacement salvaged parts,  normally second hand from eBay sellers, or posting your valuable computer to some company in London who you don`t know.

MIcro Soldering Iron

Soldering iron is an inseparable part of a Macbook logic board repair tool kit. The responsibility of the Soldering iron is to generate the heat that is needed to melt the solder, which is a metal alloy that is used for creating the permanent bond between multiple metal pieces or to separate a piece of metal from the other.

The tool comes with two parts – a metal tip that can be heated and an insulated handle to grab the tool. This soldering iron comes in handy repairs and installation, and limited assembly of electronics. Thus, this is one of the most vital tools needed for Macbook logic board repairs. 

Micro Soldering Pencil

Technically speaking, a micro soldering pencil is the same as a micro soldering iron, and carries out the same task as the micro soldering iron. There is one difference though, between the two.

While the soldering iron is used to deal with relatively bigger circuits, specialists conducting Macbook repairs in Prospector or other Adelaide suburbs would use a micro soldering pencil to deal with spare parts and circuits that are too small to be soldered by the normal soldering iron .

Soldering Tips 

The soldering tips are the top most detachable portions of the soldering irons. These are pointed stuff, and are available in extremely thinner dimensions. The Macbook’s logic board is made up of innumerable microscopic internal components that can be dealt with under the microscope only and only by these immensely finer tips.

2UUL Solder Paste

This is not a tool strictly speaking, but s paste, which is a mixture of finely powdered soldering metal, which comes as minute flux and spheres. The main function of this paste is to connect the components of the PCB or printed circuit board. The techies would apply the paste directly to the logic board and then the components are carefully put at the respective places manually. 

Hot Air Station 

This is another very important micro soldering component that is needed by the specialists conducting Macbook repair in Golden Grove. Also termed as a hot air gun, it is basically a heating tool,which is used for melting the existing soler. This device applies heat and once the soldering melts, they loosen up and can be easily removed or appropriately placed as per the requirements.

These are the tools sans which, it is impossible to conduct micro soldering the logic boards of Macbook.

Any problem with the programmer or repair skill, welcome to leave us to comment

iPad can make work easier and more efficient. High-resolution screens can display engaging images and videos. But once something goes wrong, it becomes very difficult to fix. For those who rely on their equipment every day, deciding whether to repair it or replace it with a new one can be difficult. Ultimately, users need to weigh the pros and cons to determine which option is best for their situation. PHONEFIX will describe the pros and cons of both options.

The benefits of professional repair

While it is possible to make some repairs to your iPad on your own, taking it in to be professionally repaired is generally the best solution. Experts may detect specific problems that users may overlook if they attempt the repair, Service providers offer professional repairs for broken or broken screens, audio issues, iPad charging slots that don't work, iPads that won't connect to Wi-Fi, and batteries that drain quickly. The experts also have the tools and components they can install to prevent further damage later.

Plus, experts are less likely to make mistakes when repairing an iPad. They are trained to repair thousands of devices on a regular basis, and they also have good phone repair tools. So their technique was perfected. If users try to repair the device themselves, they may not only void the warranty, but they may risk causing more damage.

Weigh up the costs

The cost of your iPad repair depends on the level of damage done to it. If the broken device is taken to Apple, the starting price for most minor repairs is $199 plus a service fee. However, if users take their damaged iPad to a general electronics specialist, the cost of repair may be significantly lower.

Meanwhile, the cost of a standard new iPad starts at around $329. The latest iPad Pro can even be as high as $1,649.

Generally, the rule of thumb is that if the repair cost is half or two-thirds the cost of replacing your device, then investing in a new iPad may be the better option. However, it’s also important to note that newer iPad models may cost more to repair, and users are advised to consult a technician on the cost of repair before agreeing to the service.

Time is of the essence

When considering whether to replace or repair your broken iPad, your decision may be influenced by how soon you need the device.

The simplest iPad repair can take as little as two minutes, whereas ordering a replacement can sometimes take two weeks with shipping. It’s worth noting that iPads with more significant damage may take longer to fix.

Of course, there is also the option of buying a brand-new iPad from the Apple store. While this option may cost significantly more, it is a quick way of accessing a new device.

Consider sentimental value

Some users might find that they don’t want to part from their iPad. Perhaps it was a gift, or they haven’t gotten around to storing documents on the device into the cloud. Whatever the reason, if the iPad has sentimental value, parting from it can be difficult.

Not everybody forms an attachment to their device, but for those who do, taking it for repair may be the better option, no matter the cost.

Success lies in mastering the details, no matter how small. In the early stage of mobile phone maintenance, there is usually solder paste or solder wire, and their functions are the same. But many people don't know which one to use for maintenance! So, today, PHONEFIX will explain their advantages and disadvantages for your reference.

Today we will give examples of two products from Mechanic, namely: Mechanic BGA rosin solder wire and Mechanic lead-free BGA solder paste.

Definition of both:

What is solder wire?

Solder wire is an alloy or mixture of tin and lead (leaded solder) or tin, silver and copper (lead-free solder). Other compositions are possible, but tin/lead ( Sn/Pb ) and tin/silver/copper ( Sn/Ag/Cu ) are widely used and accepted.

Tin/lead solder wire is called leaded solder wire, while tin/silver/copper solder wire is called lead-free solder wire because it does not contain lead.

What is Solder Paste?

Solder paste is a mixture of metal alloys, fluxes, and solvents made into a viscous solder paste. This thin layer acts as a medium to attach the component to the printed circuit board (PCB).

Solder paste comes in different thicknesses, from very thin to about 50 microns. Thicker formulations can be used for stencil printing, while thinner formulations require screen printing techniques.

Advantages of both:

What are the advantages of solder wire?

1. Good welding performance;
2. higher strength;
3. Good corrosion resistance;
4. easy to operate;

What are the advantages of solder paste?

1. Accurate solder placement;
2. No need for messy brushes;
3. Easy board cleanup and rework capability;
4. High-yield soldering reduces time to manufacture circuit boards;

Disadvantages of both:

What are the disadvantages of solder wire?

1. higher cost;
2. greater thermal impact;
3. Not suitable for high temperature;
4. Silver element is volatile;

What are the disadvantages of solder paste?

1. Solder paste is difficult to clean;
2. It takes longer than stencil printing and hand placement;
3. Requires stricter process control procedures (requiring extensive testing);

The role of both:

What is the use of solder wire?

Solder wire is used to solder electronic components, ICs or jumper wires. Since the introduction of RoHS (Restriction of Hazardous Substances) in electronics, more and more mobile phone manufacturers have started using lead-free solder. Lead-free solder wire comes in a variety of compositions, but the most common composition is tin/silver/copper in a ratio of 96.5:3.0:0.5.

What is solder paste used for?

Solder paste at room temperature can initially adhere electronic components to a given position. After AiXun H310D Internet BGA Rework Station is heated to a certain temperature, when the solvent and some additives evaporate, the tin powder melts and the soldered parts are connected to the pad , forming a permanently connected solder joint after cooling.

Conclusion

To ensure you are using the best solder paste or wire for the job, work with a full-service manufacturer who is familiar with your electronics assembly requirements, constraints, compliance issues, and more. PHONEFIX will work closely with you to determine the best option for your product.
