1

00:00:02,600 --> 00:00:04,133

now let's start to scrape

2

00:00:04,133 --> 00:00:06,466

after flattening the low mouth solder

3

00:00:10,200 --> 00:00:12,966

rotary air gun 2 and 30 degrees

4

00:00:12,966 --> 00:00:15,566

and the air volume level is 3 to four

5

00:00:19,266 --> 00:00:22,366

it is consistent with the temperature of rebolling

6

00:00:28,800 --> 00:00:30,566

let's test from the middle area

7

00:00:30,566 --> 00:00:32,533

to see if the team has melted

8

00:00:38,500 --> 00:00:42,466

now the pads are flat indicate that the tin has melted

9

00:00:42,500 --> 00:00:44,500

then slowly scrape around

10

00:00:54,300 --> 00:00:56,000

the edge must be clean

11

00:01:21,600 --> 00:01:24,066

turn the direction when you scrape the edge

12

00:01:32,800 --> 00:01:34,866

when there is too much glue on the blade

13

00:01:34,900 --> 00:01:36,466

let's clean it first

14

00:01:37,866 --> 00:01:39,766

and then continue to scrape

15

00:01:52,533 --> 00:01:53,999

there are some places on this

16

00:01:54,000 --> 00:01:56,200

edge where the team has not melted

17

00:01:56,200 --> 00:01:57,933

after blowing for a long time

18

00:01:59,333 --> 00:02:00,699

because they were not covered

19

00:02:00,700 --> 00:02:03,166

when we flattened the low melt solder

20

00:02:05,733 --> 00:02:07,566

we cannot scrape directly

21

00:02:07,900 --> 00:02:11,066

otherwise it is easy to scrape the pads off

22

00:02:13,300 --> 00:02:16,566

those places that have not been scraped flat

23

00:02:16,566 --> 00:02:18,333

we will flatten the low melt

24

00:02:18,333 --> 00:02:20,699

solder and continued scrape later

25

00:02:21,133 --> 00:02:22,199

like this edge

26

00:02:23,600 --> 00:02:26,733

because when the iron is flattening on the edge

27

00:02:26,766 --> 00:02:28,266

the glue is thicker

28

00:02:31,733 --> 00:02:34,166

it's not easy to stick in some places

29

00:02:34,333 --> 00:02:36,133

we cannot scrape it cleanly

30

00:02:36,533 --> 00:02:38,799

so we'll just repeat the process

31

00:02:38,866 --> 00:02:41,766

flatten a low melt solder and scrape

32

00:02:41,766 --> 00:02:44,266

don't think about scraping it all at once

33

00:02:44,566 --> 00:02:47,999

it's easy to break off the pads and harm the main board

34

00:03:13,900 --> 00:03:16,066

look this edge is not clean

35

00:03:16,066 --> 00:03:19,366

we have to flatten the low melt solder and scrape again
