1

00:00:02,766 --> 00:00:04,866

Same fault as last video

2

00:00:05,566 --> 00:00:07,233

Loose insurance components

3

00:00:07,800 --> 00:00:10,133

We can also use another method to repair

4

00:00:10,766 --> 00:00:13,666

At this time we need to use a soldering iron

5

00:00:14,166 --> 00:00:17,766

We first use a soldering iron to remove the loose components

6

00:00:20,333 --> 00:00:23,933

Use a soldering iron to heat the solder joints and tinning

7

00:00:28,266 --> 00:00:29,400

Two solder joints

8

00:00:29,633 --> 00:00:32,900

Dip some medium melt solder on the tip of the soldering iron

9

00:00:33,400 --> 00:00:35,100

This will make it rounded

10

00:00:36,933 --> 00:00:39,533

After making sure there is solder on it

11

00:00:40,066 --> 00:00:42,266

Let's cut a piece of desoldering wick

12

00:00:46,266 --> 00:00:51,733

Then separate a pinch of copper wire in the desolder wick from the inside to separate it

13

00:00:54,300 --> 00:00:59,933

Then use a scalpel to cut off the bent position at the front of the separated copper wire

14

00:01:00,666 --> 00:01:02,066

Make the front straighter

15

00:01:03,533 --> 00:01:07,900

At this time, we use this copper wire to connect the insurance component

16

00:01:11,400 --> 00:01:16,100

Put the copper wire to the right of the solder joint on the side farther from us

17

00:01:16,866 --> 00:01:20,533

Because most people hold a soldering iron in their right hand

18

00:01:20,900 --> 00:01:23,833

Then push it from right to left with the soldering iron

19

00:01:24,100 --> 00:01:27,666

In this way, the copper wire is soldered to a solder joint

20

00:01:28,266 --> 00:01:32,033

Then put the copper wire on the side close to us on the solder joint first

21

00:01:32,300 --> 00:01:33,800

Heat with a soldering iron

22

00:01:34,000 --> 00:01:35,566

Melt the solder underneath

23

00:01:37,200 --> 00:01:40,566

This copper wire is connected to the two solder joints now

24

00:01:40,833 --> 00:01:43,066

Then cut this copper wire with a blade

25

00:01:45,700 --> 00:01:46,866

Clean with the brush

26

00:01:49,133 --> 00:01:51,466

We mainly demonstrate the method of connection

27

00:01:53,033 --> 00:01:57,366

The component I disassembled is not necessarily an insurance inductor

28

00:01:57,800 --> 00:02:01,633

Both sides of the solder joints are grounded like the bottom side

29

00:02:02,666 --> 00:02:04,633

It dissipates heat very fast

30

00:02:05,500 --> 00:02:08,933

This leads to the less rounded soldering of the solder joint

31

00:02:09,033 --> 00:02:10,366

But it's solidified

32

00:02:12,666 --> 00:02:14,966

We mainly observe the method of welding

33

00:02:16,133 --> 00:02:18,866

I just randomly dismantled a component

34

00:02:20,333 --> 00:02:22,533

This is how to connect with a soldering iron

35

00:02:22,666 --> 00:02:24,266

We have other ways to obeserve

36

00:02:25,666 --> 00:02:27,500

Burn this with a soldering iron

37

00:02:30,133 --> 00:02:34,200

Also, there should be a little bit of solder on the solder joints

38

00:02:34,366 --> 00:02:36,933

There is a little solder on both solder joints

39

00:02:37,300 --> 00:02:38,900

Still use copper wire

40

00:02:41,233 --> 00:02:44,066

We will directly disassemble it on the motherboard

41

00:02:44,900 --> 00:02:46,566

This can be more accurate

42

00:02:49,700 --> 00:02:52,533

Cut off the one that sticks to the dirty stuff at the top

43

00:02:55,100 --> 00:02:56,133

Get rid of it

44

00:02:59,466 --> 00:03:01,200

Then place it near the component

45

00:03:04,733 --> 00:03:07,666

Use a blade to cut a piece about the size of the component

46

00:03:12,733 --> 00:03:13,633

Put it aside

47

00:03:18,000 --> 00:03:19,600

Let's adjust the direction

48

00:03:22,333 --> 00:03:23,933

It's easier to operate

49

00:03:24,233 --> 00:03:25,500

Straight-air gun

50

00:03:25,700 --> 00:03:28,800

450 degrees with maximum air volume

51

00:03:28,966 --> 00:03:33,100

Hold the copper wire with tweezers and place it on the two pins of the component

52

00:03:33,200 --> 00:03:35,000

Then blow it with a hot air gun

53

00:03:35,600 --> 00:03:36,566

Blow and leave

54

00:03:36,733 --> 00:03:37,866

Repeat doing that

55

00:03:45,166 --> 00:03:48,700

It is obvious to see that the solder is wrapped on the copper wire

56

00:03:51,200 --> 00:03:52,466

So we're done welding

57

00:03:58,166 --> 00:04:00,766

The excess on both sides can be cut off

58

00:04:06,033 --> 00:04:09,066

Dip the brush into the PCB cleaner to clean it

59

00:04:16,200 --> 00:04:23,266

The solder joints that are repaired in this way will look more perfect than the second one we repaired with a soldering iron

60

00:04:27,866 --> 00:04:32,466

This is our repair method when our insurance components are loose or damaged
