00:00:00,633 --> 00:00:02,833

iPhone common terms explanation

2

00:00:03,166 --> 00:00:07,100

In this lesson, we will mainly explain the meaning of moving board and grinding

3

00:00:08,700 --> 00:00:09,700

Moving board

4

00:00:10,933 --> 00:00:13,766

Moving board refers to welding the chips on the deformed

5

00:00:13,766 --> 00:00:15,933

and corroded mainboard to a good mainboard

6

00:00:17,400 --> 00:00:19,966

This welding process is the board moving process

7

00:00:20,300 --> 00:00:24,433

The chip of the moving board is the same as the chip of the hard solution ID

8

00:00:25,466 --> 00:00:29,033

This picture refers to the chips that need to be soldered when moving the board

9

00:00:31,733 --> 00:00:32,400

Grinding

10

00:00:32,566 --> 00:00:36,766

Grinding refers to removing the chips on the mainboard through mechanical equipment

11

00:00:38,066 --> 00:00:41,800

The damage of mechanical equipment to the mainboard is relatively low

12

00:00:42,033 --> 00:00:44,100

Because when we use the air gun to solder,

13

00:00:44,133 --> 00:00:46,866

if the temperature and feel are not well controlled,

14

00:00:47,166 --> 00:00:50,966

the chip may be dismantled or the bottom of the board may be damaged

15

00:00:51,366 --> 00:00:55,900

The mainboard ground by mechanical equipment reduces the difficulty of our welding,

16

00:00:56,066 --> 00:00:58,233

improves the maintenance efficiency,

17

00:00:58,566 --> 00:01:01,500

and also improves the efficiency of moving the board

18

00:01:02,100 --> 00:01:03,966

This picture shows the grinding machine,

19

00:01:03,966 --> 00:01:07,500

which is specially used to grind the chips on the mainboard of the mobile phone

20

00:01:08,866 --> 00:01:11,733

The picture shows the chip ground by the grinder

21

00:01:12,533 --> 00:01:16,633

When grinding, we generally grind off the chips that need to be replaced,

22

00:01:16,733 --> 00:01:18,766

such as the cpu and baseband

23

00:01:19,166 --> 00:01:23,500

Next, let's take a look at the process of grinding the chip by the grinding machine

24

00:01:59,233 --> 00:02:03,033

Now, the mainboard we see is the bottom of the board ground by the grinder,

25

00:02:03,333 --> 00:02:06,366

the CPU and baseband have been ground by the grinder

26

00:02:07,733 --> 00:02:10,800

Ok, this is the introduction of moving board and grinding
