00:00:03,366 --> 00:00:04,333

Hello,everyone

2

00:00:05,166 --> 00:00:10,233

Today, I will explain to you how to disassemble and weld the glued chip on the motherboard

3

00:00:11,200 --> 00:00:18,133

Through observation, the black glue can be clearly seen in the gap between the glued chip and the surrounding components

4

00:00:18,300 --> 00:00:19,800

We call it a glued chip

5

00:00:21,100 --> 00:00:25,466

We need to use some tools in the process of disassembling this kind of chip

6

00:00:26,466 --> 00:00:31,766

The first is to separate the residual glue in the gap between the chip and the surrounding components

7

00:00:32,533 --> 00:00:35,433

This tool is called the edge glue knife

8

00:00:36,766 --> 00:00:39,533

What I'm holding right now is an edge glue knife

9

00:00:40,366 --> 00:00:42,400

It's a metal piece of iron

10

00:00:43,066 --> 00:00:45,100

Then make the front position thinner

11

00:00:46,000 --> 00:00:49,733

Then use this thin sheet to cut back and forth in the gap

12

00:00:49,933 --> 00:00:50,966

To cut the glue

13

00:00:51,466 --> 00:00:54,233

The newly bought blade may be slightly thicker

14

00:00:54,766 --> 00:00:56,166

We need to sand the front

15

00:00:56,900 --> 00:00:58,800

This is a new one I bought back

16

00:01:01,466 --> 00:01:03,066

I need to sand the front part

17

00:01:05,700 --> 00:01:08,000

When I bought it, the front was thicker

18

00:01:08,433 --> 00:01:09,300

To thin it

19

00:01:10,300 --> 00:01:14,900

Let's compare these two, one polished and the other unpolished

20

00:01:15,633 --> 00:01:18,466

The thickness of the back is basically the same

21

00:01:20,533 --> 00:01:23,466

Then the sharp point in the front has been polished

22

00:01:25,566 --> 00:01:27,533

It's narrowed on both sides

23

00:01:29,400 --> 00:01:34,700

After grinding, the sharp point in the front should also be rounded a little bit

24

00:01:35,200 --> 00:01:38,466

Like mine, the front tip has been smoothed

25

00:01:38,700 --> 00:01:40,966

It is not easy to scratch the motherboard

26

00:01:41,600 --> 00:01:43,100

This is the first knife

27

00:01:44,100 --> 00:01:46,400

The second tool is for chip removal

28

00:01:47,000 --> 00:01:48,266

The chip is glued

29

00:01:48,966 --> 00:01:54,766

It can't be picked up with tweezers after blowing directly like the ordinary glue-free chips

30

00:01:55,100 --> 00:01:56,633

After we blow this chip

31

00:01:57,000 --> 00:02:00,766

Put a thin piece of metal in the gap between the chip and the motherboard

32

00:02:01,500 --> 00:02:04,266

After putting it in, twist the handle

33

00:02:04,733 --> 00:02:06,200

Or just lift it up

34

00:02:06,566 --> 00:02:07,833

To pry up this chip

35

00:02:08,366 --> 00:02:12,366

At this time, you need to use a knife like this to pry the chip

36

00:02:13,066 --> 00:02:16,000

This is what the knife looked like when I bought it

37

00:02:16,466 --> 00:02:18,566

Grind the front to an arc angle

38

00:02:19,866 --> 00:02:21,633

Grind it on the sandpaper

39

00:02:22,066 --> 00:02:23,100

Round the front part

40

00:02:23,600 --> 00:02:24,566

As for the edge

41

00:02:25,466 --> 00:02:27,733

The edge of the new blade is very sharp

42

00:02:28,233 --> 00:02:30,533

And there may be some burrs on the edges

43

00:02:31,433 --> 00:02:34,033

We also need to smooth this burr on this edge

44

00:02:35,066 --> 00:02:36,633

This is a grinded one

45

00:02:37,633 --> 00:02:39,000

Let's look at the front

46

00:02:40,366 --> 00:02:41,666

Relatively round

47

00:02:42,600 --> 00:02:43,700

So is the edge

48

00:02:44,433 --> 00:02:48,200

Just grind back and forth on the sandpaper a few times

49

00:02:49,966 --> 00:02:58,533

Another one is that after the chip is removed, it is necessary to clean up the glue remaining on the motherboard and the glue remaining on the chip

50

00:02:59,533 --> 00:03:01,400

We're going to use a glue scraper

51

00:03:02,266 --> 00:03:05,300

The glue scraper uses No.16 knife blade

52

00:03:06,433 --> 00:03:08,800

This is a new No.16 cutter blade

53

00:03:09,433 --> 00:03:10,433

Then grind it

54

00:03:11,933 --> 00:03:13,833

Narrow this area of the blade

55

00:03:16,166 --> 00:03:18,066

Narrow the area I'm pinching now

56

00:03:18,433 --> 00:03:23,266

Then blunt the tough edge in front of the knife which you can see a small beveled edge

57

00:03:26,866 --> 00:03:30,100

Round the tip that is in contact with the chip at the front

58

00:03:32,800 --> 00:03:36,700

The tip of the back part in contact with the chip should also be rounded

59

00:03:38,333 --> 00:03:39,500

After grinding

60

00:03:40,566 --> 00:03:42,566

The finished state is like this

61

00:03:43,300 --> 00:03:44,333

One is narrowed

62

00:03:45,833 --> 00:03:49,533

The other is that the pointed position in the front is rounded

63

00:03:51,266 --> 00:03:53,400

The position of the rear is rounded

64

00:03:54,633 --> 00:03:57,033

These are the three knives we need to use

65

00:03:58,500 --> 00:04:00,066

No.16 glue scraper

66

00:04:00,633 --> 00:04:02,400

This is the edge glue knife

67

00:04:03,166 --> 00:04:04,933

There's also a chip knife
