1

00:00:01,566 --> 00:00:03,833

Next, we will start to flatten the chip

2

00:00:08,966 --> 00:00:12,500

Cut the sloder suction wire to a length of about 2 cm

3

00:00:13,033 --> 00:00:16,100

Then fold it in half twice to make four layers

4

00:00:21,633 --> 00:00:24,833

Then put the solder suction wire on the surface of this chip

5

00:00:26,833 --> 00:00:29,933

Add some soldering oil, and then remove the tin

6

00:00:34,800 --> 00:00:36,900

But we don't use the soldering iron

7

00:00:37,500 --> 00:00:39,000

after blowing the tin

8

00:00:39,533 --> 00:00:42,766

We are using a tweezer to hold this suction wire to sweep

9

00:01:32,000 --> 00:01:34,666

Now, the pad has been completely flattened

10

00:01:35,900 --> 00:01:38,166

Let's wait for it to cool down and clean it

11

00:01:56,233 --> 00:01:58,366

Put a dust-free cloth on the surface,

12

00:01:58,400 --> 00:01:59,433

and brush on it

13

00:02:29,800 --> 00:02:31,266

Now, we're done with the pads

14

00:02:33,766 --> 00:02:36,966

Now let's put some soldering oil on the points that broke off

15

00:02:42,900 --> 00:02:45,766

We don't need to worry about the points broke off in the middle

16

00:02:47,433 --> 00:02:51,266

Because these points in the middle area are powered or grounded,

17

00:02:53,200 --> 00:02:54,766

there is no control signal

18

00:02:55,233 --> 00:02:57,133

There are 2 more points broke off

19

00:03:15,866 --> 00:03:18,500

The green oil on one spot is a little thick

20

00:03:20,366 --> 00:03:21,766

Swipe it to the side

21

00:03:29,433 --> 00:03:30,633

don't make it too thick

22

00:03:31,033 --> 00:03:33,333

Otherwise, it will hit the steel mesh

23

00:03:35,366 --> 00:03:37,266

Let's cure it with the curing light

24

00:04:09,366 --> 00:04:10,366

On the CPU, we can see

25

00:04:10,366 --> 00:04:11,633

In the middle of it,

26

00:04:11,966 --> 00:04:16,166

there is a frame made up of a blank area with no soldering points

27

00:04:23,700 --> 00:04:26,733

Outside this wider border area is the signal line

28

00:04:29,533 --> 00:04:33,933

There will also be some power supply points, ground and empty points

29

00:04:35,500 --> 00:04:38,500

Signal control lines are all outside this frame

30

00:04:41,566 --> 00:04:45,833

And then all the points in this box are power supplies and ground cables

31

00:04:48,466 --> 00:04:50,900

There are multiple points of power supply

32

00:04:51,266 --> 00:04:54,733

Maybe there are hundreds of them, or at least a dozen or twenty

33

00:04:55,600 --> 00:04:58,100

So, a few points broke off in the middle area.

34

00:04:58,300 --> 00:04:59,566

we don't have to worry about it
