Introduction of short circuit burning detection tools for iPhone standby circuit

2

00:00:06,766 --> 00:00:10,666

We can use different types of burning detection tools in the maintenance

3

00:00:12,400 --> 00:00:16,300

There are three common types, the first is an adjustable power supply,

4

00:00:16,400 --> 00:00:18,266

the second is a short circuit detector,

5

00:00:18,533 --> 00:00:20,433

and the third is a burning battery

6

00:00:20,600 --> 00:00:24,700

Most of the adjustable power supplies we use when repairing are 5A

7

00:00:26,700 --> 00:00:28,366

But when detecting short circuit,

8

00:00:28,633 --> 00:00:30,200

5A current may not work

9

00:00:31,200 --> 00:00:35,000

It is best to choose an adjustable power supply for more than 10A

10

00:00:35,166 --> 00:00:37,300

but the price of it will be more expensive

11

00:00:37,566 --> 00:00:39,400

The higher current, the more expensive

12

00:00:41,900 --> 00:00:45,466

Or you can buy a professional tool, a short circuit detector

13

00:00:51,100 --> 00:00:54,300

This tool can adjust the voltage and output current

14

00:00:56,266 --> 00:00:57,866

It is a professional tool

15

00:01:03,733 --> 00:01:05,566

The third tool is the burning battery

16

00:01:06,733 --> 00:01:10,500

Generally, this kind of burning battery is modified with waste batteries

17

00:01:11,800 --> 00:01:15,066

The disadvantage is that the voltage cannot be adjusted,

18

00:01:15,066 --> 00:01:17,266

and the highest is 4.2V

19

00:01:17,566 --> 00:01:21,366

It can only be used to repair the fault of electrical short circuit

20

00:01:23,166 --> 00:01:26,066

The advantage is that the current is relatively large

21

00:01:26,066 --> 00:01:27,966

and the cost is relatively low

22

00:01:29,300 --> 00:01:31,400

This is a ready-made burning battery

23

00:01:32,033 --> 00:01:35,433

Next, we will demonstrate the production method of this battery
