00:00:00,733 --> 00:00:02,866

How to use the location diagram

2

00:00:03,400 --> 00:00:07,800

This video mainly demonstrates how to find the corresponding component objects

3

00:00:08,866 --> 00:00:12,266

through the location diagram when viewing the schematic diagram

4

00:00:14,033 --> 00:00:16,566

Let me demonstrate with the Apple model first

5

00:00:18,733 --> 00:00:24,433

Open the schematic diagram, location diagram and physical diagram of the iPhone 11 Pro Max

6

00:00:25,033 --> 00:00:29,433

Let's check the position of C1730 in the real object

7

00:00:35,766 --> 00:00:39,500

Search for the position number of the component in the location diagram

8

00:00:49,100 --> 00:00:53,833

This capacitor is the fourth capacitor from left to right under the CPU

9

00:00:56,666 --> 00:01:00,200

After opening the physical map, find the corresponding chip

10

00:01:02,166 --> 00:01:05,733

The third row below the chip is the fourth chip from left to right

11

00:01:07,766 --> 00:01:12,466

This component is the component C1730 in the schematic diagram

12

00:01:15,200 --> 00:01:18,133

Next, let me demonstrate the Huawei model,

13

00:01:18,600 --> 00:01:23,500

how to find the position of the component in the real object through the schematic diagram

14

00:01:25,166 --> 00:01:30,133

We open the P40 pro schematic diagram, location diagram and physical map

15

00:01:32,233 --> 00:01:33,833

In the schematic diagram,

16

00:01:34,133 --> 00:01:38,833

determine the component position number, such as L2501

17

00:01:40,400 --> 00:01:43,700

Then search for that location number in the location diagram

18

00:01:48,666 --> 00:01:52,400

After searching, find the corresponding component in the real object

19

00:01:52,400 --> 00:01:54,700

according to the location of the component

20

00:02:01,200 --> 00:02:02,700

In the physical picture,

21

00:02:03,166 --> 00:02:07,300

this component is the component that needs to be checked in the drawing just now,

22

00:02:07,700 --> 00:02:09,500

L2501

23

00:02:12,100 --> 00:02:14,766

Through the demonstrations of the above two models,

24

00:02:14,933 --> 00:02:18,866

we found that the viewing methods of different mobile phones are the same

25

00:02:20,800 --> 00:02:22,733

Ok, that's it for this lesson
