1

00:00:03,000 --> 00:00:06,500

Next, we will de-glue the upper cover and the middle layer

2

00:00:07,300 --> 00:00:08,800

230 degrees

3

00:00:10,300 --> 00:00:11,633

Rotary-air hot gun

4

00:00:12,333 --> 00:00:14,200

Air volume level 3-4

5

00:00:17,400 --> 00:00:19,500

We'll start scraping from the middle part

6

00:00:24,000 --> 00:00:27,266

Although there is no pad in the middle but some remaining glue

7

00:00:28,600 --> 00:00:30,066

Scrape here gently

8

00:00:30,500 --> 00:00:31,433

Then to the left

9

00:00:54,400 --> 00:00:56,700

The position on the edge may not be scraped

10

00:00:57,933 --> 00:00:59,533

We just turn a direction

11

00:01:07,733 --> 00:01:09,333

The cover has been scraped

12

00:01:10,433 --> 00:01:12,666

Now let's do it with the middle layer

13

00:01:29,166 --> 00:01:31,300

The temperature is still the same as usual

14

00:01:31,800 --> 00:01:33,266

230 degrees

15

00:01:33,600 --> 00:01:35,533

Air volume level 3-4

16

00:01:36,066 --> 00:01:38,866

But we can't use sanded No. 16 blade

17

00:01:39,300 --> 00:01:40,666

We gotta find a new one

18

00:01:43,433 --> 00:01:44,966

We must put the blade flat

19

00:01:45,600 --> 00:01:47,966

Scrape backwards flat like this

20

00:01:48,800 --> 00:01:51,200

Never use the tip of the blade to scrape

21

00:01:51,866 --> 00:02:00,633

The position with the solder bead should be flat and gently scraped back and forth

22

00:02:01,333 --> 00:02:03,500

Just scrape the glue off the surface

23

00:02:04,300 --> 00:02:07,000

It is also a material similar to the plastic

24

00:02:07,500 --> 00:02:09,833

So this position can be easily scratched

25

00:02:20,933 --> 00:02:22,233

After scrapping

26

00:02:23,166 --> 00:02:27,666

Let's look at this area of the glass and the area between the glass and the pads

27

00:02:30,466 --> 00:02:32,866

Which is the area where my blade went

28

00:02:33,166 --> 00:02:35,900

Then also the area from the pad to the edge of the chip

29

00:02:36,433 --> 00:02:38,066

Scrape these three positions

30

00:02:38,600 --> 00:02:42,966

Now we can see that there is still a lot of glue in the three rows of pads

31

00:02:43,500 --> 00:02:44,833

We don't need to scrape here

32

00:02:45,433 --> 00:02:49,400

Put the blade flat on the surface, so that you can scrape it slowly

33

00:02:49,866 --> 00:02:54,666

Whether there is more glue or less glue in the middle position, don't worry about it

34

00:02:54,966 --> 00:02:57,400

We just need to scrape this plane out

35

00:02:59,333 --> 00:03:00,533

Let's scrape this side

36

00:03:15,333 --> 00:03:20,066

After scraping horizontally, we adjust the direction and scrape vertically.

37

00:03:20,533 --> 00:03:21,966

It'll take a little longer

38

00:03:22,666 --> 00:03:25,500

Let's slide this red block slightly towards the back

39

00:03:26,233 --> 00:03:27,033

Stuck the chip

40

00:03:35,600 --> 00:03:37,833

And the location where we start the operation

41

00:03:38,133 --> 00:03:39,100

Let's see it

42

00:03:40,233 --> 00:03:42,566

The knife is operated from this position

43

00:03:42,933 --> 00:03:44,900

Don't put it on this solder bead

44

00:03:45,133 --> 00:03:48,066

There are three rows of solder beads horizontally

45

00:03:48,233 --> 00:03:50,433

Do not put the blade in this position

46

00:03:50,600 --> 00:03:52,466

Scrape down from the third row

47

00:03:54,600 --> 00:03:57,200

Scrape to the top of the first row below

48

00:03:57,300 --> 00:03:58,600

Scrape here and stop

49

00:04:18,866 --> 00:04:20,333

It's basically scraped

50

00:04:22,133 --> 00:04:23,866

Then we turn the chip side over

51

00:04:30,333 --> 00:04:32,933

Because we start from this position to this position

52

00:04:35,133 --> 00:04:37,633

Then there will be a corner that can never be scraped

53

00:04:38,300 --> 00:04:42,333

According to the method we just did, it will never be scraped

54

00:04:43,166 --> 00:04:47,200

So at this time, we need to scrape the corners sideways like this

55

00:04:51,933 --> 00:04:55,300

This corner has been scraped flat and change with a new one

56

00:05:04,533 --> 00:05:05,966

This is the scraped chip

57

00:05:10,066 --> 00:05:11,166

After scraping

58

00:05:11,633 --> 00:05:16,600

Just that the excess glue on the surface that is above the plane we see is scraped off

59

00:05:20,133 --> 00:05:22,766

Do not scrape the original black glue of this chip

60

00:05:23,833 --> 00:05:26,966

If you scrape it a little bit, it will be scratched

61

00:05:27,500 --> 00:05:29,400

Especially this location with pads

62

00:05:30,066 --> 00:05:31,733

Very easy to scratch

63

00:05:32,366 --> 00:05:33,733

So don't do it
