1

00:00:01,866 --> 00:00:04,366

Next we still use absorbent cotton

2

00:00:04,833 --> 00:00:06,633

To wrap the tweezers with it

3

00:00:08,200 --> 00:00:10,266

Then wash off the remaining flux

4

00:00:14,766 --> 00:00:16,066

Like the area above

5

00:00:17,266 --> 00:00:21,966

After the PCB cleaner volatilizes, there are still some oil stains

6

00:00:22,700 --> 00:00:24,566

This requires repeated cleaning

7

00:00:25,233 --> 00:00:26,666

The oil has been cleaned

8

00:00:26,766 --> 00:00:28,433

Now let's apply green oil

9

00:00:33,933 --> 00:00:36,133

The thinner the green oil, the better

10

00:00:36,733 --> 00:00:38,100

Must not be thick

11

00:00:38,566 --> 00:00:41,300

Otherwise it will affect our welding later

12

00:00:43,766 --> 00:00:46,033

Then cure it with a curing light

13

00:00:54,633 --> 00:00:57,733

Then use a blade to scrape out where we need to weld

14

00:01:03,066 --> 00:01:08,566

When scratching this solder joint, we must scratch it till it is reflective and shiny

15

00:01:11,833 --> 00:01:14,766

You don't need to scrape the entire solder joint out

16

00:01:15,500 --> 00:01:19,133

A part of green oil can be left on the edge for stabilization

17

00:01:21,500 --> 00:01:27,300

Even after you've scraped off all the green oil, this solder joint is relatively easy to loosen

18

00:01:31,833 --> 00:01:34,100

We left a little bit of the top edge

19

00:01:35,033 --> 00:01:39,100

In this way, it can stick a little tighter and won't fall off

20

00:01:46,566 --> 00:01:49,666

We left some in the upper right on the right side of this

21

00:01:51,333 --> 00:01:53,400

Then wash off the scraped green oil

22

00:01:57,000 --> 00:02:00,100

We have fixed two different solder joint drop points

23

00:02:00,966 --> 00:02:04,333

There is basically no third wiring method on the motherboard

24

00:02:05,466 --> 00:02:08,700

Either to wire from the edge, or from the bottom

25

00:02:09,333 --> 00:02:10,366

No other method

26

00:02:10,800 --> 00:02:12,666

After you have learned both

27

00:02:12,933 --> 00:02:16,266

You can repair them in the same if the solder joints are dropped
