00:00:03,000 --> 00:00:06,033

Next we start to solder the copper wire on the chip

2

00:00:11,166 --> 00:00:14,366

Let's put a little flux on the pads of this chip first

3

00:00:32,200 --> 00:00:35,333

The 2nd pad from the upper right corner, counting down,

4

00:00:35,333 --> 00:00:36,400

is a grounded pad,

5

00:00:55,766 --> 00:01:00,200

After the copper wire is welded firmly, cut about 2 to 3 cm

6

00:01:10,300 --> 00:01:13,333

Solder the copper wire to the second pad from the bottom

7

00:01:13,333 --> 00:01:15,766

to the top of the second row on the left,

8

00:01:16,000 --> 00:01:18,100

this pad is 1.8V

9

00:01:41,533 --> 00:01:47,266

We use this special copper wire for jumping wire, 0.02mm diameter

10

00:01:50,033 --> 00:01:51,200

Ok, that's it

11

00:01:57,933 --> 00:02:01,966

Then the 5th and 7th pads from the left on the bottom row,

12

00:02:01,966 --> 00:02:06,133

which are two signal points of I2C, one is clock and one is data

13

00:02:32,966 --> 00:02:35,400

After the copper wire is soldered firmly,

14

00:02:36,500 --> 00:02:40,000

then we put a little tin on the other side of the copper wire

15

00:02:40,000 --> 00:02:43,500

to make sure it will be easier to solder to the mainboard later

16

00:03:48,333 --> 00:03:50,700

Just put a little on the tip of the top

17

00:04:21,300 --> 00:04:24,633

Well, four copper wires are glued to the top of the pads

18

00:04:27,900 --> 00:04:30,600

In this way, we have already dealt with the chip
