1

00:00:03,366 --> 00:00:04,966

After this loosening

2

00:00:06,066 --> 00:00:11,133

We use a scalpel or a knife to scrape the corroded motherboard solder spots first

3

00:00:19,700 --> 00:00:20,966

Scrape lightly

4

00:00:46,800 --> 00:00:51,100

Then slightly scrape the pins of the plastic connector sideways

5

00:00:55,666 --> 00:00:57,466

Hard to see from this angle

6

00:01:06,433 --> 00:01:09,066

This way you can barely see the location

7

00:01:09,900 --> 00:01:11,266

Scrape this pin

8

00:01:11,266 --> 00:01:15,166

Because under the microscope, the angle can't stand too much

9

00:01:26,566 --> 00:01:28,266

After the pins are scratched

10

00:01:28,600 --> 00:01:30,233

Next let's weld

11

00:01:32,266 --> 00:01:39,400

Although this debris and oxidized residue have been scraped off, it still needs to be cleaned again

12

00:01:41,566 --> 00:01:44,900

The surrounding components next to it are corroded

13

00:01:45,666 --> 00:01:47,333

We also need to fix it later
