1

00:00:03,000 --> 00:00:06,766

We have welded two copper wires to these two broken wires

2

00:00:07,266 --> 00:00:08,866

We can directly solder chip

3

00:00:09,133 --> 00:00:12,500

A single copper wire has a very small contact area

4

00:00:12,800 --> 00:00:14,466

May cause poor contact

5

00:00:14,966 --> 00:00:19,733

In order to increase the contact area, we can wrap the copper wire in a circle

6

00:00:20,566 --> 00:00:27,333

Use a pair of tweezers and a blade or two pairs of tweezers to work together to bend the copper wire

7

00:00:34,700 --> 00:00:39,666

The folded circle should not be larger than the original pit of the solder joint

8

00:00:46,466 --> 00:00:49,733

After folding the circle, we start to add green oil

9

00:00:53,733 --> 00:00:56,500

Green oil mainly plays a role similar to glue

10

00:00:57,033 --> 00:00:58,466

to fix this copper wire

11

00:01:00,333 --> 00:01:04,533

Prevent the copper wire from shifting after melting during the soldering process

12

00:01:08,633 --> 00:01:10,433

Do not apply too much green oil

13

00:01:11,066 --> 00:01:13,366

If it is too much,it'll hit the chip

14

00:01:14,366 --> 00:01:17,100

As a result, we can't solder the chip to it

15

00:01:19,833 --> 00:01:24,933

After the green oil is applied, we use a UV curing lamp to dry the green oil

16

00:01:29,733 --> 00:01:34,533

This kind of high-power curing lamp can cure the green oil in about 10 seconds

17

00:01:37,466 --> 00:01:40,533

After curing, use the blade to test it

18

00:01:42,866 --> 00:01:44,600

Not too solidified yet

19

00:01:46,766 --> 00:01:48,366

Can be cured a little longer

20

00:01:53,266 --> 00:01:54,433

It's almost done

21

00:01:54,900 --> 00:01:58,233

Then scrape out the copper wire at the position of the solder joint

22

00:01:59,300 --> 00:02:00,966

The welding position at the back

23

00:02:01,700 --> 00:02:04,533

There is no need to scratch the location of the wiring

24

00:02:05,533 --> 00:02:07,900

Scrape this area of the solder joint

25

00:02:15,566 --> 00:02:18,933

Then use a brush to clean the scraped green oil debris

26

00:02:23,633 --> 00:02:27,033

Now the copper wire has been completely covered with green oil

27

00:02:28,400 --> 00:02:30,733

Don't worry about brushing it off

28

00:02:32,266 --> 00:02:36,166

In this way, the solder joint of the surface wiring is repaired
