00:00:00,933 --> 00:00:03,766

In this video we're going to talk bout the USB chips

2

00:00:05,466 --> 00:00:10,266

The USB chip is the lightning port that Apple has adopted since the iPhone5

3

00:00:12,000 --> 00:00:15,300

The USB chip is a chip that manages the interface

4

00:00:16,833 --> 00:00:21,166

In the iPhone 5, the location number of the USB chip is U2

5

00:00:22,200 --> 00:00:24,333

It's particularly prone to break,

6

00:00:25,000 --> 00:00:28,300

and a replacement of USB chip can fix the problem

7

00:00:29,266 --> 00:00:33,800

That's why repairmen call the USB chip in all Apple models U2

8

00:00:37,500 --> 00:00:41,566

USB chip is mainly responsible for mobile phone connection function,

9

00:00:42,666 --> 00:00:46,966

data conversion function, charging voltage detection and so on

10

00:00:48,766 --> 00:00:51,300

The chip damage will cause a lot of problems,

11

00:00:52,233 --> 00:00:53,933

such as stuck white apple,

12

00:00:54,366 --> 00:00:58,266

white apple restart, brush error, etc

13

00:00:59,100 --> 00:01:03,700

After the USB chip is damaged, we need to replace it with the same model

14

00:01:04,566 --> 00:01:09,633

In iphones, the USB chip is universal in many cases

15

00:01:10,600 --> 00:01:14,300

The iPhone 6 to iPhone 7p models, for example,

16

00:01:14,900 --> 00:01:18,766

have the same USB chip model and look and can be interchangeable

17

00:01:19,700 --> 00:01:22,233

iPhone 8 to iPhone 11 pro max models,

18

00:01:22,500 --> 00:01:26,233

which all have the same USB chip model and can be interchangeable

19

00:01:28,333 --> 00:01:31,133

The surface of USB chips is mostly black

20

00:01:33,100 --> 00:01:36,366

Before the iPhone 7, the USB chip was square,

21

00:01:37,633 --> 00:01:41,133

and iPhone 8 and up, the USB chip is rectangular

22

00:01:42,800 --> 00:01:45,333

Let's get to know the USB chip in real life

23

00:01:49,066 --> 00:01:51,366

The mainboard is an iPhone 7 mainboard,

24

00:01:51,600 --> 00:01:55,533

and its USB chip is located in the lower right corner of the hard drive

25

00:01:55,966 --> 00:01:58,300

The chip is square with a black surface

26

00:02:01,000 --> 00:02:03,333

The mainboard is an iPhone 8p mainboard,

27

00:02:03,600 --> 00:02:07,366

and its USB chip is also located in the lower right corner of the hard drive

28

00:02:07,933 --> 00:02:12,866

The chip is rectangular, and 1612A1 can be seen faintly

29

00:02:15,733 --> 00:02:18,133

The mainboard is an iPhone xs mainboard,

30

00:02:18,566 --> 00:02:21,500

and its USB chip is located inside the shield

31

00:02:21,700 --> 00:02:23,266

We've removed the shield,

32

00:02:24,900 --> 00:02:28,466

and this chip is a USB chip, and it's also a rectangle

33

00:02:30,066 --> 00:02:33,366

We can faintly see the model 1612-A1

34

00:02:34,800 --> 00:02:37,100

The mainboard is an iPhone 11 mainboard,

35

00:02:38,833 --> 00:02:41,700

and its USB chip is located inside the shield

36

00:02:44,300 --> 00:02:47,800

When we remove the shield, we can see the rectangular chip

37

00:02:48,900 --> 00:02:51,466

From iPhone 8 to 11 pro max models,

38

00:02:52,700 --> 00:02:55,933

the USB chip model is the same and can be interchangeable

39

00:02:57,500 --> 00:02:59,600

So that's all for this lesson
