1

00:00:03,000 --> 00:00:05,333

Next, we start to remove the glue on the chip

2

00:00:06,466 --> 00:00:11,200

Rotary air gun, about 230 degrees, and the air volume is level 3-4

3

00:00:14,133 --> 00:00:16,000

The temperature is the same as when we

4

00:00:16,000 --> 00:00:17,966

usually remove the glue on the mainboard

5

00:00:27,800 --> 00:00:30,333

Take the rotary air gun to blow the chip first

6

00:00:30,533 --> 00:00:33,033

Blow the residual soldering tin on the pads

7

00:00:46,600 --> 00:00:49,766

The soldering tin is now clearly reflective and shiny

8

00:00:50,166 --> 00:00:51,966

It means it's in a melted state

9

00:00:52,600 --> 00:00:54,900

Then shovel with a size 4 flat blade

10

00:00:56,400 --> 00:00:59,300

Sharpen the blade a bit blunt and round the corners a bit

11

00:01:10,200 --> 00:01:12,500

Do not shovel directly with the new blade,

12

00:01:13,166 --> 00:01:16,466

otherwise, it is easy to shovel the yellow circuit board behind

13

00:02:14,900 --> 00:02:17,833

There may still be a little bit of residual tin on the chip,

14

00:02:18,166 --> 00:02:19,433

after shoveling the glue

15

00:02:20,133 --> 00:02:24,200

It is best not to use the soldering iron to press the solder wick to flatten

16

00:02:26,366 --> 00:02:28,433

Put a little soldering oil on it

17

00:02:28,533 --> 00:02:31,666

We can clearly see that there are many thin wires on it

18

00:02:33,566 --> 00:02:35,233

If you flatten too hard,

19

00:02:35,333 --> 00:02:37,800

the thin insulating layer on the surface of the thin wire

20

00:02:37,800 --> 00:02:41,100

can easily be scratched and cause a short circuit

21

00:02:42,533 --> 00:02:46,033

Let's sweep it with the used solder wick to remove the tin

22

00:02:48,066 --> 00:02:52,466

It must be used, and there is tin on it, so that it is not easy to disperse

23

00:02:57,366 --> 00:03:00,733

Set the temperature of the rotary air gun 230 degrees

24

00:03:03,800 --> 00:03:07,433

In this way, the excess tin on the surface is swept away at once.

25

00:03:32,500 --> 00:03:34,100

Okay, we're done with this chip
