00:00:03,200 --> 00:00:10,333

Today, I will introduce a consumable used in the maintenance of electronic products - PCB cleaner

2

00:00:11,900 --> 00:00:17,100

PCB cleaner is mainly used to clean the solder marks on the surface of the motherboard

3

00:00:17,500 --> 00:00:20,200

Such as welding oil,rosin

4

00:00:20,600 --> 00:00:27,633

It can also clean the traces of corrosion and oxidation on the surface of some water-infiltrated motherboards

5

00:00:27,966 --> 00:00:31,066

PCB cleaner is a strong corrosive liquid

6

00:00:31,233 --> 00:00:34,300

We must not clean some plastic surfaces when using

7

00:00:34,666 --> 00:00:37,500

Such as mobile phone shell,computer shell

8

00:00:37,800 --> 00:00:39,500

I have a remote control now

9

00:00:39,800 --> 00:00:42,966

Let's dip a little PCB cleaner and take a look at it

10

00:00:45,233 --> 00:00:49,000

After a few seconds, the plastic surface has softened

11

00:00:50,900 --> 00:00:52,800

It fell off when I wiped it again

12

00:00:56,600 --> 00:00:58,900

PCB cleaner is very corrosive

13

00:00:59,133 --> 00:01:02,366

It must not be used to clean some plastic casings

14

00:01:03,866 --> 00:01:09,566

Another thing to note is that PCB cleaners are mostly flammable and explosive materials

15

00:01:10,366 --> 00:01:14,266

We must use a dedicated bottle when using PCB cleaner

16

00:01:16,566 --> 00:01:17,966

This one is safe

17

00:01:19,833 --> 00:01:21,266

It looks like a tower

18

00:01:23,133 --> 00:01:25,033

It's not easy to overturn

19

00:01:25,433 --> 00:01:29,933

It is best not to use that kind of high plastic bottle, which is unstable

20

00:01:30,266 --> 00:01:31,466

After use

21

00:01:31,800 --> 00:01:36,300

It is best to cover the bottle with a plastic cap to prevent evaporation

22

00:01:36,466 --> 00:01:40,266

It will be equipped with a plastic cover when it leaves the factory

23

00:01:40,566 --> 00:01:43,333

We must pay attention when buying PCB cleaner

24

00:01:43,700 --> 00:01:47,433

That is try to avoid buying some flammable materials

25

00:01:47,700 --> 00:01:54,133

Most of the PCB cleaners are blended with flammable chemicals such as alcohol and banana oil

26

00:01:54,500 --> 00:01:59,833

Now there is a new type of environmentally friendly PCB cleaner in the market

27

00:02:00,000 --> 00:02:02,633

Its main ingredient is trichloroethylene

28

00:02:02,800 --> 00:02:07,033

This kind of PCB cleaner is basically difficult to light with a lighter

29

00:02:07,933 --> 00:02:09,633

Relatively safe to use

30

00:02:10,300 --> 00:02:14,900

But the material of trichloroethylene is also a strong corrosive liquid

31

00:02:16,266 --> 00:02:20,033

We still can't clean the surface of some plastics when we use it

32

00:02:20,300 --> 00:02:23,666

That's all about PCB cleaner.Thank you for watching.
