1

00:00:02,600 --> 00:00:06,466

Next, we start to install this chip on the new screen

2

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

Before installing the chip, let's clean it a little to prevent dirt on it

3

00:00:13,800 --> 00:00:15,766

We need to use alcohol to clean

4

00:00:16,800 --> 00:00:18,700

it is best not to use cleaner,

5

00:00:19,033 --> 00:00:22,300

because cleaner can easily scratch the surface of the cable

6

00:00:24,800 --> 00:00:29,300

Like this area, it was slightly bruised when it was ground just now

7

00:00:29,733 --> 00:00:34,066

If you wash it with cleaner, the surface layer will easily fall off

8

00:00:34,300 --> 00:00:38,500

Then heat it up a little so that there is a little temperature on the cable

9

00:00:39,766 --> 00:00:42,900

Then we apply a layer of flux to it evenly

10

00:00:49,000 --> 00:00:53,533

Put a reball paper towel on the bottom to make it less easy to dissipate heat

11

00:00:58,600 --> 00:01:01,633

If you put an iron or silicone pad underneath,

12

00:01:01,833 --> 00:01:06,200

the heat dissipation is too fast, and then the tin is not easy to melt

13

00:01:08,700 --> 00:01:11,800

After the flux is applied, let's place the chip

14

00:01:12,166 --> 00:01:14,800

Note that pin 1 is facing down,

15

00:01:14,800 --> 00:01:17,200

pin 1 is leading to the bottom of the cable

16

00:01:39,166 --> 00:01:41,966

After setting, use a rotary air gun,

17

00:01:42,066 --> 00:01:45,233

adjust the temperature to about 250 degrees,

18

00:01:45,633 --> 00:01:48,166

and the air volume to 3-4 level

19

00:01:48,533 --> 00:01:51,466

Blow it until the chip returns to its place

20

00:01:58,500 --> 00:02:00,400

Well, we can see that it moved a bit

21

00:02:01,066 --> 00:02:03,133

If you're stable to hold the tweezer,

22

00:02:03,766 --> 00:02:06,133

you can use a tweezer to gently touch it,

23

00:02:06,333 --> 00:02:08,500

and the chip can return to its position

24

00:02:17,900 --> 00:02:19,066

OK, we're done

25

00:02:20,533 --> 00:02:25,333

If we repair the machines from the customer, there is no need to make glue

26

00:02:26,733 --> 00:02:29,166

For refurbishment of second-hand phones,

27

00:02:29,266 --> 00:02:31,500

or for after-sales warranty,

28

00:02:31,600 --> 00:02:34,266

you can use glue to ensure a perfect appearance

29

00:02:42,500 --> 00:02:45,233

We only need to solder the chip on for maintenance,

30

00:02:45,500 --> 00:02:49,533

the iron sheet will not be loose, basically there will be no problem

31

00:02:54,400 --> 00:02:58,333

If you use glue, you need to wash the soldering oil with alcohol,

32

00:02:58,700 --> 00:03:01,833

then apply glue, or the black green oil,

33

00:03:02,466 --> 00:03:04,533

and cure it with the curing light
