1

00:00:00,833 --> 00:00:02,900

Identification of the motherboard number of the iPhone mobile phone

2

00:00:03,200 --> 00:00:05,400

In this course, we mainly explain the understanding and function of the motherboard number of the iPhone mobile phone

5

00:00:09,566 --> 00:00:10,900

What is the board number?

6

00:00:11,000 --> 00:00:13,433

The board number refers to the identification of the motherboard model

7

00:00:14,433 --> 00:00:18,466

The same series of mobile phone motherboards use different hardware, and different models will be marked on the motherboard

9

00:00:22,733 --> 00:00:25,500

The model is a board number of the motherboard

10

00:00:26,200 --> 00:00:27,733

For example, iPhone 7 motherboard, which uses Qualcomm baseband and Intel baseband

12

00:00:30,666 --> 00:00:33,600

The use of Qualcomm baseband is a board number

13

00:00:33,666 --> 00:00:36,200

The one using the Intel baseband is another board number

14

00:00:36,200 --> 00:00:37,600

The board numbers of the two boards are different.

16

00:00:40,000 --> 00:00:42,100

What is the use of the plate number?

17

00:00:42,500 --> 00:00:44,333

We can determine which model the motherboard is based on the board number of the motherboard.

20

00:00:50,666 --> 00:00:52,266

What are the characteristics of this model?

twenty one

00:00:52,500 --> 00:00:54,933

We can also query the corresponding drawings according to the board number

twenty three

00:00:56,466 --> 00:00:58,533

How to check the plate number

twenty four

00:00:58,966 --> 00:01:01,133

The board number is generally in the open position on the front or back of the motherboard

26

00:01:04,366 --> 00:01:05,566

The motherboard of the Apple mobile phone will identify the board number starting with 820

29

00:01:10,866 --> 00:01:13,933

For example, in the picture, iPhone 7 Qualcomm motherboard

30

00:01:14,200 --> 00:01:17,433

Its board number is on the reverse side of the main board

31

00:01:18,166 --> 00:01:22,633

The board number of this model is 820-00188, which refers to the board number of the Qualcomm baseband motherboard

33

00:01:26,833 --> 00:01:29,600

In some models, it will be on the front of the motherboard.

34

00:01:29,966 --> 00:01:31,600

For example iPhone 6s motherboard

35

00:01:31,933 --> 00:01:35,766

Its board number is in the open space at the top of the front of the motherboard

36

00:01:35,933 --> 00:01:40,166

Its plate number is 820-5507

37

00:01:40,466 --> 00:01:43,166

Then this kind of board number mark is the position of the single-layer motherboard mark

39

00:01:45,400 --> 00:01:47,400

Next, let's take a look at the double-layer motherboard

40

00:01:47,633 --> 00:01:50,833

iPhone 11 motherboard is divided into upper and lower layers

41

00:01:50,966 --> 00:01:54,400

The board on the upper layer will mark a board number

42

00:01:54,433 --> 00:01:56,966

The lower motherboard will also identify a board number

43

00:01:57,333 --> 00:02:02,166

The upper logo of iPhone 11 is 820-01523

44

00:02:02,533 --> 00:02:03,733

The lower layer is on the opposite side

46

00:02:05,300 --> 00:02:08,766

It is identified as 820-01525

47

00:02:09,200 --> 00:02:10,566

Different models have different plate numbers

49

00:02:13,033 --> 00:02:14,633

If we don't recognize the main board, we can use the board number to determine which model it is

53

00:02:19,500 --> 00:02:23,000

The board number of the motherboard is in the empty space at the top

54

00:02:23,566 --> 00:02:25,100

After zooming in, we can see that the board number of the motherboard is 820-01209

56

00:02:29,300 --> 00:02:32,033

Let's compare it in the table below to see which model it is

59

00:02:36,200 --> 00:02:38,233

In the table we can see that the board number of the iPhone XR is 820-01209

61

00:02:43,400 --> 00:02:45,900

Indicates that it is the motherboard of the XR model

62

00:02:46,100 --> 00:02:48,066

This table is a comparison table of motherboard numbers commonly used in the iPhone

65

00:02:51,366 --> 00:02:54,233

Different models have different board numbers

67

00:03:00,666 --> 00:03:02,433

Next, we will query the information of the model according to the board number

69

00:03:05,066 --> 00:03:07,433

Let's take the iPhone XR as an example

70

00:03:07,800 --> 00:03:09,866

We enter 820-01209 in the search box

72

00:03:13,933 --> 00:03:15,566

After searching, we can see some information about the model

74

00:03:17,633 --> 00:03:20,233

This is based on the board number to query

75

00:03:20,566 --> 00:03:23,133

So let's end this lesson first.
