1

00:00:03,000 --> 00:00:05,066

Now let's reball another chip

2

00:00:05,633 --> 00:00:07,800

This one is relatively smaller

3

00:00:13,533 --> 00:00:14,800

No right stencil

4

00:00:16,733 --> 00:00:17,966

No right position

5

00:00:22,500 --> 00:00:24,566

If there is no suitable stencil

6

00:00:24,733 --> 00:00:26,600

We can also reball in this way

7

00:00:26,966 --> 00:00:30,200

As long as all the solder joints of the chip are exposed

8

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

Then we can reball

9

00:00:32,300 --> 00:00:34,033

During Android Repair

10

00:00:34,233 --> 00:00:36,100

This method is often used

11

00:00:36,533 --> 00:00:40,033

As long as the holes of the stencil can correspond to the chips

12

00:00:40,500 --> 00:00:42,766

Then you can use this stencil to reball

13

00:00:50,066 --> 00:00:52,066

Blow on a large area first

14

00:00:52,766 --> 00:00:55,000

Don't be in a hurry to melt the solder

15

00:00:55,700 --> 00:00:57,700

This is how any chip is reballed

16

00:01:03,800 --> 00:01:05,466

Blow for about 1 minute

17

00:01:06,233 --> 00:01:08,033

Stop and blow from the corner

18

00:01:10,100 --> 00:01:11,800

Withdraw the hot air gun

19

00:01:12,000 --> 00:01:14,266

Do not rush to loosen the tweezers

20

00:01:16,200 --> 00:01:20,166

Chips reballed in this way have no problems with solder joints

21

00:01:21,233 --> 00:01:23,333

Here are the two chips we reballed
