1

00:00:02,600 --> 00:00:04,166

Next we start to repair

2

00:00:04,666 --> 00:00:09,300

First, we repair the relatively simple solder joints of this surface wiring

3

00:00:09,666 --> 00:00:12,366

We start by scraping out the connected lines

4

00:00:15,833 --> 00:00:19,166

This long strip of copper foil is the previous contact

5

00:00:24,900 --> 00:00:28,466

This long strip of copper foil is the contact of this solder joint

6

00:00:29,233 --> 00:00:31,900

After we scraped the two copper foils out

7

00:00:32,100 --> 00:00:33,366

Tin this copper foil

8

00:00:37,800 --> 00:00:41,066

We use tweezers to hold a little bit of medium melt solder

9

00:00:43,500 --> 00:00:46,133

183 degree medium melt solder

10

00:00:46,633 --> 00:00:49,833

Do not use low melt tin for poor line repairing

11

00:00:50,066 --> 00:00:54,900

The circuit that has been repaired by low melt solder will fall off with a light touch

12

00:00:55,333 --> 00:00:57,000

Apply to this solder joint

13

00:00:57,566 --> 00:01:00,566

Then stick it to the copper foil with a soldering iron

14

00:01:01,366 --> 00:01:02,700

Then deal with this one

15

00:01:06,600 --> 00:01:09,100

There is a lot of solder on the solder joints

16

00:01:09,866 --> 00:01:11,966

This will affect the operation

17

00:01:12,333 --> 00:01:15,566

Now let's flatten the solder joint with low melt solder first

18

00:01:16,100 --> 00:01:18,766

Soldering iron stick a little low melt solder

19

00:01:21,300 --> 00:01:22,533

Add a little flux

20

00:01:31,033 --> 00:01:31,733

Clean it

21

00:01:33,766 --> 00:01:35,933

Put a dust-free cloth on the surface

22

00:01:36,233 --> 00:01:38,733

Clean with a brush dipped in PCB cleaner

23

00:01:38,833 --> 00:01:40,633

Wash off the dirty things first

24

00:01:44,266 --> 00:01:48,733

In this way, the two points that need to be repaired have been scraped out

25

00:01:49,100 --> 00:01:50,200

Now they are tinned
