00:00:00,700 --> 00:00:05,766

Hello everyone, in this lesson we will talk about the tools needed to repair the graphics card

2

00:00:06,566 --> 00:00:08,766

First is the soldering tool

3

00:00:09,266 --> 00:00:13,266

Soldering tools include: air gun, soldering iron, heating table, BGA

4

00:00:15,000 --> 00:00:19,066

Air gun, soldering iron are necessary, heating table is also necessary

5

00:00:20,566 --> 00:00:24,500

The two pictures on the right are two different heating stages

6

00:00:25,000 --> 00:00:29,800

The main function of the heating table is to heat the back of the graphics card

7

00:00:30,366 --> 00:00:33,200

Because the graphics card board layer is relatively thick,

8

00:00:33,466 --> 00:00:36,300

and the area of the middle ground layer is relatively large

9

00:00:36,500 --> 00:00:39,966

This causes the graphics card to dissipate heat very quickly

10

00:00:40,733 --> 00:00:47,100

Because the mainboard of the graphics card dissipates heat very quickly, the soldering time will be longer

11

00:00:47,500 --> 00:00:52,600

And some chips that are sensitive to temperature may die due to heating for too long

12

00:00:53,800 --> 00:00:56,133

For example the video memory

13

00:00:56,900 --> 00:01:01,666

If you don't use the heating table, the video memory is basically not good to change.

14

00:01:02,766 --> 00:01:07,666

Therefore, when changing the video memory, you must use a heating table to heat the bottom of the video card

15

00:01:09,033 --> 00:01:12,733

The heating table generally needs to be opened at a temperature of about 200 degrees

16

00:01:13,300 --> 00:01:15,333

Both heating stages can

17

00:01:16,133 --> 00:01:20,033

However, when using the above heating platform, the graphics card needs to be padded

18

00:01:21,400 --> 00:01:25,400

Do not allow the components on the graphics card to directly contact the heating aluminum plate

19

00:01:25,666 --> 00:01:28,733

BGA is not a must-have tool

20

00:01:28,966 --> 00:01:34,300

Because for the maintenance of graphics cards, BGA can only be used to desolder GPU

21

00:01:35,066 --> 00:01:37,900

And the GPU we usually disassemble less.

22

00:01:38,133 --> 00:01:42,933

Therefore, BGA can be without if the conditions are not allowed

23

00:01:43,533 --> 00:01:47,066

Next, let's look at the test tools for repairing graphics cards

24

00:01:47,366 --> 00:01:52,000

The test tools for repairing the graphics card include multimeter, PCIE adapter card,

25

00:01:52,500 --> 00:01:55,833

video memory test hard disk, mainboard and graphics card test base

26

00:01:58,466 --> 00:02:03,866

First of all, the multimeter is a must-have for maintenance.

27

00:02:04,700 --> 00:02:07,600

PCIE riser card is this thing

28

00:02:08,166 --> 00:02:11,200

PCIE riser card has two main purposes

29

00:02:11,600 --> 00:02:16,133

The first use is to break away from the mainboard and desktop power supply

30

00:02:16,700 --> 00:02:19,100

to repair the power supply of the graphics card

31

00:02:19,566 --> 00:02:25,400

The second purpose is to transfer the graphics card from the mainboard for easy measurement

32

00:02:26,766 --> 00:02:30,566

PCIE riser card is a very useful tool

33

00:02:31,366 --> 00:02:36,433

It can improve the efficiency of graphics card maintenance by more than 50%

34

00:02:37,066 --> 00:02:42,766

Let's talk about its function of breaking away from the mainboard and desktop power supply

35

00:02:43,400 --> 00:02:48,833

Through the previous analysis of timing, we know that as long as the graphics card has three input voltages,

36

00:02:49,200 --> 00:02:52,500

all its power supplies will generate

37

00:02:53,066 --> 00:02:56,600

This small board can input 12V power supply

38

00:02:57,266 --> 00:03:02,500

This 12V power supply will generate a 3V power supply on the small board to the PCIE interface

39

00:03:02,666 --> 00:03:06,400

At the same time, the 12V power supply will also be supplied to the PCIE interface.

40

00:03:06,966 --> 00:03:10,533

Then the 3V and 12V on the golden finger will be

41

00:03:10,900 --> 00:03:14,566

We only need to provide 12V power supply to this small board,

42

00:03:14,700 --> 00:03:18,166

and the 3V and 12V of the golden finger are enough

43

00:03:18,800 --> 00:03:22,733

We prepare one or two 8PIN to double 8PIN cables,

44

00:03:22,900 --> 00:03:26,733

and then we can supply power to the small board and the graphics card at the same time.

45

00:03:27,533 --> 00:03:31,133

Connect the 8PIN to double 8PIN cable to the adjustable power supply,

46

00:03:31,300 --> 00:03:34,900

then you can use the adjustable power supply to power the graphics card

47

00:03:35,766 --> 00:03:39,566

In this way, the main board and desktop power supply can not be used, and the maintenance

48

00:03:40,266 --> 00:03:42,400

The efficiency will be much higher

49

00:03:43,066 --> 00:03:46,000

The third is the video memory test hard drive

50

00:03:46,400 --> 00:03:50,366

It is the hard disk used to store the video memory test program

51

00:03:51,266 --> 00:03:52,966

Fourth, the mainboard

52

00:03:53,700 --> 00:03:58,366

This mainboard must support switching between independent display output and integrated display output

53

00:03:58,766 --> 00:04:03,666

Because when repairing the graphics card, we often encounter machines that do not display

54

00:04:04,000 --> 00:04:07,800

At this time, we need to use the integrated display to test the graphics card

55

00:04:09,733 --> 00:04:12,900

The last one is the graphics card test base

56

00:04:13,133 --> 00:04:15,266

It's not a necessity

57

00:04:15,733 --> 00:04:17,800

It's the thing on the right

58

00:04:18,200 --> 00:04:23,066

Its main function is to fix the mainboard and graphics card.
