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

In this lesson,

2

00:00:01,500 --> 00:00:04,333

we will talk about the mainboard number of Android phones

3

00:00:04,533 --> 00:00:07,833

The mainboard number of an Android phone is a set of numbers

4

00:00:07,833 --> 00:00:10,700

used in a brand to distinguish specific models

5

00:00:12,300 --> 00:00:16,200

The placement of components with different board numbers is different,

6

00:00:16,333 --> 00:00:20,400

and the drawings of mainboards with different board numbers are also different

7

00:00:22,366 --> 00:00:24,633

For example, in the picture on the left,

8

00:00:24,633 --> 00:00:31,233

the number that starts with HL is the board number of this mainboard, HL2ELLEM

9

00:00:33,633 --> 00:00:37,933

Then the board number of the Android mobile phone mainboard is generally regular,

10

00:00:38,100 --> 00:00:40,666

and it is on the A side of the mainboard

11

00:00:41,700 --> 00:00:43,466

What is the A side of the mainboard?

12

00:00:43,966 --> 00:00:46,033

Generally, the mainboard has two sides

13

00:00:46,366 --> 00:00:49,266

One side has the battery holder and power supply,

14

00:00:49,300 --> 00:00:51,266

and there are many connection sockets

15

00:00:51,366 --> 00:00:54,033

This side is called the A side of the mainboard

16

00:00:56,400 --> 00:00:59,933

The board number is generally located on the A side of the mainboard,

17

00:00:59,966 --> 00:01:02,633

and is designed at the corners of the four sides

18

00:01:05,600 --> 00:01:07,833

For example, this mobile phone,

19

00:01:08,000 --> 00:01:10,566

its board number is close to the edge of the mainboard

20

00:01:11,000 --> 00:01:12,066

23

00:01:19,833 --> 00:01:21,333

For example, this picture,

24

00:01:21,566 --> 00:01:25,266

which is a screenshot of a part of Huawei's mobile phone mainboard

25

00:01:25,433 --> 00:01:30,633

The board number of this mainboard is HL6VOGUEMVA

26

00:01:33,500 --> 00:01:38,166

The board number of Oppo mobile phone mainboard generally starts with the number 2,

and is composed of numbers and letters

28

00:01:41,300 --> 00:01:43,366

For example, in the picture on the right,

29

00:01:43,600 --> 00:01:47,366

the board number of this mainboard is 2AD027

30

00:01:47,533 --> 00:01:51,900

42

00:02:45,466 --> 00:02:49,833

What is the role of the board number of the mobile phone mainboard in the actual maintenance?

43

00:02:52,133 --> 00:02:53,500

In actual maintenance,

44

00:02:53,833 --> 00:02:55,800

we sometimes receive a mainboard,

45

00:02:56,066 --> 00:02:59,166

or a whole machine that has been seriously dropped

46

00:03:02,800 --> 00:03:04,033

From the appearance,

47

00:03:04,466 --> 00:03:07,733

we can't tell what brand or model this mainboard is

48

00:03:13,733 --> 00:03:14,633

At this time,

49

00:03:14,766 --> 00:03:17,600

we can remove the mainboard and find the board number

50

00:03:18,666 --> 00:03:23,400

We can enter the board number into the Xinzhizao equipment maintenance inquiry system,

51

00:03:25,200 --> 00:03:29,566

and then we can quickly find the specific model and information of this mainboard,

52

00:03:30,033 --> 00:03:32,133

including the drawings and data

53

00:03:37,833 --> 00:03:39,133

Now, let me show you

54

00:03:39,866 --> 00:03:42,133

For example, Oppo mainboard,

55

00:03:42,600 --> 00:03:49,033

we enter this board number 2AD027 into Xinzhizao equipment maintenance query system,

56

00:03:49,733 --> 00:03:51,066

click search

57

00:03:59,333 --> 00:04:04,966

The search results include R17 2AD027 easy-to-use,

58

00:04:05,600 --> 00:04:08,800

physical scanning diagram and component map

59

00:04:15,866 --> 00:04:18,600

We can open these files directly,

60

00:04:18,900 --> 00:04:21,366

which will guide and assist our maintenance

61

00:04:28,466 --> 00:04:30,266

Well, that's it for our lesson
