Hello everyone, today I will show you the welding process of the A10 CPU used by the iPhone 7 and iPhone 7 plus

2

00:00:11,166 --> 00:00:14,533

When you get a motherboard, before going to operate the CPU

3

00:00:15,133 --> 00:00:19,300

We're going to tear off the foam tape next to the plastic connector first

4

00:00:25,633 --> 00:00:27,100

Then remove the shield

5

00:00:29,766 --> 00:00:35,033

There is a transparent hot melt adhesive on the upper side of the shield of the A10

6

00:00:35,733 --> 00:00:38,066

I'll pick this hot melt glue off first

7

00:00:38,466 --> 00:00:41,333

Rotary-air hot gun with 350 degrees

8

00:00:42,266 --> 00:00:43,800

Maximum air volume

9

00:00:45,333 --> 00:00:49,000

With a little high temperature,the hot melt adhesive will be loose

10

00:00:49,366 --> 00:00:52,600

Just blow it and take off the hot melt adhesive first

11

00:00:56,533 --> 00:00:57,800

Why would we do this?

12

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

Because sometimes it will be more

13

00:01:00,366 --> 00:01:05,400

If there are some places around where the black glue is not applied, it will wrap the components

14

00:01:05,700 --> 00:01:11,333

When the shield is removed, if the temperature is too high, some small components may be taken away

15

00:01:11,533 --> 00:01:13,466

So let's get rid of it first

16

00:01:13,633 --> 00:01:15,666

Next we start to remove the shield

17

00:01:15,766 --> 00:01:18,000

The shield of the A10 is longer

18

00:01:18,466 --> 00:01:21,766

When disassembling, we first pry it from the upper right corner

19

00:01:22,166 --> 00:01:24,766

We blow the upper half and the right side first

20

00:01:29,900 --> 00:01:30,866

It's loose here

21

00:01:32,166 --> 00:01:34,666

After loosening, then we blow the left

22

00:01:40,300 --> 00:01:42,166

After loosening the whole of it

23

00:01:43,100 --> 00:01:45,066

Let's clamp this position in the middle

24

00:01:46,900 --> 00:01:49,233

Then slightly warm up the sticker on top

25

00:01:53,666 --> 00:01:54,900

Then tear off this sticker

26

00:01:56,666 --> 00:02:00,333

In this way, we can paste it back after we finish the CPU

27

00:02:01,933 --> 00:02:03,000

It will look better

28

00:02:08,433 --> 00:02:12,033

Let's shovel the residual silicone grease on the CPU surface

29

00:02:18,400 --> 00:02:22,766

If there are larger pieces in the gap, you can also use tweezers to pick them first

30

00:02:23,300 --> 00:02:26,433

Otherwise, it will be dirty when you clean it later

31

00:02:34,766 --> 00:02:37,233

After the larger particles have been removed

32

00:02:37,466 --> 00:02:39,200

We can clean up the dirty place

33

00:02:48,400 --> 00:02:51,633

Use a brush and then dip it in the PCB cleaner to brush it

34

00:02:53,833 --> 00:02:55,633

Okay, we're done with this shield
