How To Repair iPhone Can't Connect To Bluetooth?

The Bluetooth function on the iPhone is a very practical design. Its presence not only makes the user's daily use more convenient, but also does not require a wireless network connection, which reduces costs and improves efficiency. But in the Bluetooth connection process, we may encounter problems such as unsuccessful, what should we do at this time? How to repair iPhone can't connect to Bluetooth? Today our phonefix shop team will teach you how to solve this problem.


Before you start repair this issue, make sure you do the following:

Make sure Bluetooth is enabled. Go to Settings and turn on Bluetooth.

Charge your iPhone/iPad and the device you want to pair with.

Your iPhone and Bluetooth devices should be close to each other.

Do not get close to the USB port and Wi-Fi router, as the router and USB port may cause Bluetooth interference.

Has your Bluetooth device been recently paired with other gadgets? If yes, turn off the device or disable Bluetooth.

Try connecting to another Bluetooth device

The first thing you should try to find out is whether there is a problem with your iPhone or Bluetooth device. So, use another Bluetooth device (it doesn't have to be the same) and try to connect both and see if any one or two devices are successfully connected to your iPhone. If you find that a Bluetooth device does manage to connect to your iPhone and the other does not, then this means the problem is with the Bluetooth device and not your iPhone. If you find that the iPhone cannot connect to two Bluetooth devices, it means the problem is with the iPhone.

Switch Bluetooth


We will start with the simplest thing that usually solves the problem. All you have to do is turn off Bluetooth, wait a few seconds, then enable it again. Swipe up from the bottom of any screen to open the Control Center, tap the Bluetooth icon and turn off Bluetooth. Click the icon again to open it. Alternatively, go to Settings > Bluetooth, turn it off, wait and reopen.

Restart iPhone / iPad and Bluetooth accessories

Hold down the iPhone Sleep/Wake button and drag the slider when "Slide Off Power" appears

After turning off the iPhone, press and hold the Sleep/Wake button until you see the Apple logo.

Then restart the Bluetooth accessory. Once this is done, try pairing your Bluetooth device with your iPhone.


Turn off pairing mode on the Bluetooth device and turn it on again


Almost every Bluetooth device has a switch or button for easy pairing (pairing mode). Sometimes even if you have tried everything to fix the iPhone not connected to Bluetooth, the problem is probably not in your iPhone but in the Bluetooth device itself. It may encounter a glitches or errors, or it's just not the first time you have a very good connection.

Step 1: Try a Bluetooth device paired with your iPhone and find the switch or button you want to press sync/pair.

Step 2: Just press and hold the button or turn on the Bluetooth device to remove it from the Bluetooth pairing mode.

Step 3: Wait approximately 30 seconds, then press the button or flip the switch again to pair the device with the iPhone. Try pairing your device with your iPhone now, just like using Bluetooth to see if the issue is resolved.

Use iTunes to restore your iPhone to factory settings

Make sure you have the latest version of iTunes installed. Launch iTunes and connect your iPhone to your computer with the iPhone cable.

Select your device when it appears in iTunes. In the summary panel, select the "Restore iPhone" or "Restore iPad" option. Click "Restore" to confirm your operation. iTunes will erase your iPhone/iPad and will install the latest iO. Your device will reboot. Please set it to new.

BGA Welding Tips: You Should Learn

What is BGA? Most people are a bit strange to this word, BGA's full name is Ball Grid Array. It is to make an array of solder balls at the bottom of the package substrate as the I/O end of the circuit and the printed circuit board (PCB). The device packaged with this technology is a surface mount device. With the rapid development of the electronics industry, people are increasingly demanding the functions of electronic products, and their performance is getting strong. BGA technology has emerged. In the initial time, there were doubts about the solderability and reliability of BGA components. BGA components provide a better solution for many boards. During the BGA soldering repair process, the pads are under the device and are not visible, so the usage of zoom LED stereo microscope is a good assistant. Today, our Vipfixphone team will talk about BGA welding repairs.


Check BGA Solder Joints

When repairing BGA, as the pads are under the device and are not visible, so proper soldering and inspection processes are ital.

BGA inspection is one of the most difficult tasks. Since the solder is under the BGA package and is not visible, it is extremely difficult to inspect the BGA connector. The only satisfactory method of testing BGA solder joints is to use zoom LED stereo microscope. This way you can clearly check the connectors underneath the package to help you check.

Desoldering BGA

The most common practice for desoldering BGA is to complete the desoldering with 861D hot air rework station. Here are the steps to use the hot air rework station to desolder the BGA package:

1. Apply liquid flux to both sides of the package.

2. Preheat the package from the top and bottom. Heat can be given from the bottom using preheating while using a hot air recirculation system to give heat from the top. Hakko FR-820 is the best preheater, and Hakko FR-803 is the most economical hot air SMD / BGA rework system


3. The solder balls under the BGA package will melt. Use the tweezers of the vacuum suction device to pick up the package.

Soldering BGA 

When welding BGA, it is necessary to adjust the position reasonably to ensure that the chip is between the upper and lower air outlets, and be sure to tighten the PCB to the ends with iphone fixture platform clamp, and fix it! It is standard to touch the motherboard of the motherboard without shaking.


1. Apply flux paste (non-liquid flux) to the pad. Flux helps the solder ball stick so it doesn't fall or change position.

2. Place the solder balls on the pads very carefully.

3. Apply solder paste to the bottom of the BGA package (welded surface).

4. Carefully place the solder ball in the BGA package.

5. Preheat and then apply hot air from the top and bottom.

6. The solder balls will melt and solder.

BGA welding work will be very reliable and successful if done with the correct procedure. The BGA has less heat resistance, so there is less or no damage due to overheating.

Okay, the above is the BGA soldering skill shared by our vipfixphone team. If you are interested in this article or have questions, you can contact us at www.vipfixphone.
