00:00:01,866 --> 00:00:07,833

Today I will introduce an electronic product repair tool-carving knife

2

00:00:08,200 --> 00:00:11,433

There are three types of blades we often use

3

00:00:12,566 --> 00:00:19,500

No. 16 blade, mainly used to scrape the insulating coating of circuit boards and PCBs

4

00:00:20,233 --> 00:00:24,666

Scrape out the original circuit of the motherboard for repair

5

00:00:25,066 --> 00:00:32,133

No. 11 blade is mainly used for scraping plastic slots that are corroded and oxidized by water

6

00:00:32,266 --> 00:00:34,033

Or some loose pins

7

00:00:34,533 --> 00:00:38,133

You can use this very sharp tip to test for looseness

8

00:00:38,633 --> 00:00:42,133

No. 4 blade can shovel some glued chip on the motherboard

9

00:00:42,366 --> 00:00:43,500

and residual glue

10

00:00:43,866 --> 00:00:46,366

Or apply solder paste for reballing

11

00:00:46,966 --> 00:00:52,633

Then again, this off-the-shelf irregularly shaped blade is available in the market

12

00:00:53,433 --> 00:00:57,400

There are many shapes,specifications and functions

13

00:00:57,833 --> 00:01:01,933

It can be used to pry chips, remove glue

14

00:01:02,700 --> 00:01:06,633

This flat wide blade can also be used for solder paste

15

00:01:07,300 --> 00:01:10,666

All of these blades are installed on the handle to use

16

00:01:13,433 --> 00:01:16,100

The front of the handle has a cross-shaped opening

17

00:01:18,633 --> 00:01:20,333

Loosen the back bolt

18

00:01:24,533 --> 00:01:25,933

Get a blade

19

00:01:29,966 --> 00:01:32,333

Put this blade in this cross slit

20

00:01:34,200 --> 00:01:37,466

When installing, keep your hands away from the blade

21

00:01:38,600 --> 00:01:41,333

Because the blade of the knife is very sharp

22

00:01:41,600 --> 00:01:44,600

It is easy to cut your hand if you are not careful

23

00:01:45,700 --> 00:01:48,766

After plugging into the gap, press down

24

00:01:50,200 --> 00:01:52,400

Tighten the bolt after pressing

25

00:01:55,000 --> 00:01:56,700

So the blade is installed

26

00:01:58,500 --> 00:01:59,233

For this kind of blade

27

00:01:59,233 --> 00:02:04,466

You can remove this one by itself when you need it, like this

28

00:02:07,400 --> 00:02:09,800

Install it on the handle in the same way

29

00:02:11,500 --> 00:02:15,566

That's everything about the blade and the handle.Thank you for watching
