00:00:00,900 --> 00:00:04,033

In this lesson we are going to learn about the Face chip

2

00:00:05,133 --> 00:00:06,400

In Apple's model,

3

00:00:06,733 --> 00:00:10,200

the Face chip main function is to convert the battery power supply

4

00:00:10,200 --> 00:00:14,866

into the voltage needed by the face component for lattice and flood lighting

5

00:00:17,433 --> 00:00:21,800

The Face feature is only available on Apple's iPhone x and above

6

00:00:24,033 --> 00:00:27,200

It's in these models that we can find the Face chip

7

00:00:28,933 --> 00:00:31,233

Face chip surface is silver white,

8

00:00:32,300 --> 00:00:34,933

most of the square, is a glass chip

9

00:00:35,933 --> 00:00:40,766

Face chip is mainly used to provide operating voltage for face components

10

00:00:41,400 --> 00:00:45,300

In the actual maintenance, it is less likely to be damaged

11

00:00:46,333 --> 00:00:50,300

If it's damaged, it'll disable the face function

12

00:00:51,733 --> 00:00:55,666

The chip is not tied to the CPU, it belongs to a power chip

13

00:00:57,700 --> 00:01:01,366

We need the same model to replace it when it is damaged

14

00:01:02,500 --> 00:01:05,666

Below we go to the physical mainboard to know the face chip

15

00:01:08,100 --> 00:01:09,833

The mainboard is XR model,

16

00:01:10,666 --> 00:01:14,300

its face power supply chip is in the position above the big audio

17

00:01:15,533 --> 00:01:18,366

This chip is the face power supply chip of XR,

18

00:01:19,500 --> 00:01:23,766

the surface is glass crystal, the model is difficult to identify

19

00:01:24,433 --> 00:01:26,833

This mainboard is the xs upper board,

20

00:01:28,266 --> 00:01:31,400

its face chip is in the upper reverse position

21

00:01:32,500 --> 00:01:35,066

This chip is the xs face power chip

22

00:01:37,666 --> 00:01:40,333

This is the top mainboard of the iPhone 11,

23

00:01:40,633 --> 00:01:43,300

and its face chip is to the right of the CPU

24

00:01:44,500 --> 00:01:47,100

This chip is the face power chip of 11

25

00:01:48,000 --> 00:01:50,000

Ok, that's it for this lesson
