Hello everyone, today I will show you how to safely disassemble the font library of the Android series.

2

00:00:13,600 --> 00:00:18,500

We got a mainboard, first remove the shield above the font

3

00:00:19,400 --> 00:00:22,333

This shield has a frame.

4

00:00:22,333 --> 00:00:29,100

After opening the upper cover, there is a very narrow metal strip on the edge

5

00:00:29,100 --> 00:00:35,266

This kind of frame, so we can鈥檛 cut it when we dismantle this font

6

00:00:35,666 --> 00:00:39,533

The font chip is different from other chips

7

00:00:39,533 --> 00:00:43,000

We can lift many chips from the gap on the edge

8

00:00:43,000 --> 00:00:48,300

If you use a lot of force to pry the library chip from the outside,

9

00:00:48,600 --> 00:00:52,200

the inside of the chip will be slightly deformed,

10

00:00:52,600 --> 00:01:00,600

and the internal crystal will be easily broken, making the data inside unreadable

11

00:01:00,833 --> 00:01:05,733

For example, stuck on logo, the screen does not light up and other faults,

12

00:01:05,733 --> 00:01:09,733

we must first destroy the shield before disassembling the font

13

00:01:10,033 --> 00:01:14,933

You can use scissors to cut from the edge, or you can use a sanding pen to polish

14

00:01:39,433 --> 00:01:42,833

This angle is not easy to operate

15

00:02:25,433 --> 00:02:29,233

Ok so cut it

16

00:02:30,300 --> 00:02:32,766

The side corner of the chip touched a little

17

00:02:33,433 --> 00:02:38,200

But it doesn't matter, just touched the outer black plastic protective layer

18

00:02:39,333 --> 00:02:41,633

The glass should be a little bit inward

19

00:02:42,533 --> 00:02:45,200

After cutting like this, next we start heating

20

00:02:45,200 --> 00:02:47,266

Remove this little strip

21

00:02:50,200 --> 00:02:55,266

The air volume of the straight air gun is adjusted to 450, the maximum wind

22

00:03:20,066 --> 00:03:22,866

Okay, we'll take care of this shield

23

00:03:24,066 --> 00:03:25,800

Next we scrape the edge glue

24

00:03:27,700 --> 00:03:30,000

Straight air gun or rotary air gun can be used

25

00:03:30,666 --> 00:03:34,800

The temperature is about 200 degrees, and the air volume is the largest

26

00:04:53,866 --> 00:04:58,733

This side of the lower knife is also scraped off

27

00:05:00,433 --> 00:05:02,866

Then blow the tin in this area to flatten it

28

00:05:02,933 --> 00:05:06,233

This temperature can't blow it, but it will soften a little

29

00:05:06,233 --> 00:05:08,800

Take the blade and push it to flatten the tin

30

00:05:09,400 --> 00:05:13,133

Otherwise, the back is slightly higher, and it will push the blade,

31

00:05:13,400 --> 00:05:15,433

which is not very easy to operate

32

00:05:36,933 --> 00:05:40,566

OK, that's all for this lesson
