1

00:00:02,666 --> 00:00:07,366

Next, we add a little flux to the position on the mainboard that need to be soldered

2

00:00:08,100 --> 00:00:12,633

The position of the ground wire may not be easy to solder due to the screw hole,

3

00:00:12,866 --> 00:00:14,800

so I scraped it from the side

4

00:00:14,900 --> 00:00:17,566

Then this small capacitor is a filter capacitor,

5

00:00:17,900 --> 00:00:19,766

and it is removed directly

6

00:00:20,700 --> 00:00:23,833

In this case, it will be more convenient for us to weld

7

00:00:24,833 --> 00:00:27,433

When we're ready, we'll start jumping the wires

8

00:00:28,266 --> 00:00:30,600

We are now connecting the first grounded pad

9

00:00:49,033 --> 00:00:50,433

The chip is a little light,

10

00:00:50,966 --> 00:00:53,866

and the grounded pads are all large copper foils,

11

00:00:54,500 --> 00:00:57,566

and it is more difficult to solder on the screw post

12

00:00:57,866 --> 00:01:00,533

I scraped a little bit from the position of the board

13

00:01:00,900 --> 00:01:04,733

After welding, pull it a little to see if it will loosen

14

00:01:07,533 --> 00:01:10,266

It is best to use an air gun for assistance,

15

00:01:10,366 --> 00:01:13,666

but I have a tweezer in one hand and a soldering iron in the other,

16

00:01:13,766 --> 00:01:15,500

and I can't use the air gun

17

00:01:20,366 --> 00:01:22,766

Add a little more tin paste on it

18

00:01:45,600 --> 00:01:48,700

Then we connect the 1.8V wire

19

00:02:07,500 --> 00:02:11,400

The 1.8V wire is connected to the inductor next to it

20

00:02:26,333 --> 00:02:28,833

It's not very easy to hold with the left hand

21

00:02:31,000 --> 00:02:35,633

Then the remaining 5th point is connected to the pin of the small capacitor

22

00:02:58,766 --> 00:03:02,133

Then the last one is connected to that resistor

23

00:03:29,700 --> 00:03:31,900

So, these 4 wires are connected

24

00:03:34,366 --> 00:03:36,600

It was touched by the soldering iron,

25

00:03:36,600 --> 00:03:38,833

and a little residue was stuck on it

26

00:03:39,000 --> 00:03:40,200

Then we wash it

27

00:03:53,000 --> 00:03:56,933

When washing, be sure to use absorbent cotton to wash it,

28

00:03:57,266 --> 00:03:58,633

do not use a brush,

29

00:03:58,800 --> 00:04:01,333

otherwise it will be brushed off at once

30

00:04:31,933 --> 00:04:33,233

And wish the chip

31

00:05:05,100 --> 00:05:08,033

Okay, we've already dealt with the copper wires
