00:00:03,133 --> 00:00:04,966

We use a straight air gun,

2

00:00:06,466 --> 00:00:10,266

the temperature is adjusted to about 450 degrees,

3

00:00:10,466 --> 00:00:12,533

and the air volume is the largest

4

00:00:15,133 --> 00:00:18,766

Remove the R8156 resistor on the mainboard,

5

00:00:19,666 --> 00:00:22,166

we use the point blow method to blow it,

6

00:00:25,000 --> 00:00:28,300

otherwise it will easily loosen the surrounding components

7

00:00:33,533 --> 00:00:37,033

After the resistor is removed, don't need it

8

00:00:52,733 --> 00:00:57,266

We put a little medium temperature tin paste on the bottom of the resistor

9

00:01:13,066 --> 00:01:18,066

Adjust the straight air gun to 450 degrees, the maximum air volume,

10

00:01:18,766 --> 00:01:20,666

to blow this lump of tin paste

11

00:01:42,533 --> 00:01:45,766

Remove excess residue from the surrounding area

12

00:02:00,466 --> 00:02:06,733

Then add a little tin paste to the upper pin of C8155 on the right side of the resistor

13

00:02:18,466 --> 00:02:22,633

Apply a little tin paste to any of the two pins of the large inductor

14

00:02:22,666 --> 00:02:25,666

L1800 in the lower left corner

15

00:02:33,266 --> 00:02:35,800

Heat the tin paste with a soldering iron

16

00:02:36,366 --> 00:02:39,533

and stick it to the surfaces of these two components

17

00:03:01,733 --> 00:03:03,733

And the position of the screw hole,

18

00:03:03,933 --> 00:03:06,766

or you can find other positions of the ground wire,

19

00:03:07,666 --> 00:03:09,433

we will give it some tin paste

20

00:03:19,133 --> 00:03:21,166

We use medium temperature tin,

21

00:03:21,200 --> 00:03:23,066

do not use low temperature tin,

22

00:03:23,333 --> 00:03:26,600

because the low temperature tin will not be firm after welding

23

00:03:30,666 --> 00:03:33,200

Solder the tin paste to this screw post

24

00:03:36,933 --> 00:03:38,333

Ok, it's glued
