00:00:00,533 --> 00:00:02,366

How to use the location diagram

2

00:00:03,633 --> 00:00:08,866

This lesson mainly demonstrates how to find component parameters through the location diagram

3

00:00:10,733 --> 00:00:13,933

Let's take the iPhone model as an example to demonstrate

4

00:00:14,666 --> 00:00:20,266

First open the physical map, location diagram and schematic diagram of iPhone 11

5

00:00:21,500 --> 00:00:26,633

For example, find the parameters of the component in the lower right corner of the CPU

6

00:00:29,133 --> 00:00:33,800

We find the corresponding component number in the same position in the location diagram

7

00:00:35,233 --> 00:00:39,400

The position number of this component is C4400

8

00:00:39,966 --> 00:00:43,700

We search for C4400 in the schematic

9

00:00:45,133 --> 00:00:46,200

After searching,

10

00:00:46,533 --> 00:00:51,233

the information below the component represents the parameter information of the component

11

00:00:57,566 --> 00:01:00,666

Next, let me demonstrate the Xiaomi series

12

00:01:02,233 --> 00:01:07,733

Open the physical map, location diagram and schematic diagram of Xiaomi 10PRO

13

00:01:10,800 --> 00:01:14,166

We first find the position of the component in the physical diagram

14

00:01:18,233 --> 00:01:21,500

Let's take the small component above the CPU as an example

15

00:01:23,166 --> 00:01:28,600

After we determine the position, first find the corresponding position in the location diagram,

16

00:01:29,600 --> 00:01:31,500

and then find the component number

17

00:01:32,500 --> 00:01:36,566

The component is numbered L2027 in the location diagram

18

00:01:38,800 --> 00:01:41,866

Then search for L2027 in the drawing,

19

00:01:47,800 --> 00:01:50,800

and you can see the parameters of the component after searching

20

00:01:52,833 --> 00:01:55,600

Through the demonstrations of the above two models,

21

00:01:56,300 --> 00:02:00,933

it can be found that the location diagram of different models is used in the same way

22

00:02:04,633 --> 00:02:06,633

Ok, that's all for this video
