Hello everyone, in this lesson, let's take a look at the soldering method of the chip in the 8-pin SOP package.

2

00:00:07,300 --> 00:00:14,133

When soldering this chip, we also use an air gun to solder, just like soldering capacitors

3

00:00:14,766 --> 00:00:18,900

First use tweezers to hold the chip firmly

4

00:00:19,266 --> 00:00:23,666

After clamping firmly, you can use the air gun to directly heat the chip

5

00:00:23,900 --> 00:00:29,366

The temperature of the air gun is adjusted to 450 degrees, and the air volume is adjusted to 60

6

00:00:29,566 --> 00:00:34,800

When soldering this kind of chip, it is recommended to only blow his pins instead of heating the chip body

7

00:00:35,200 --> 00:00:37,766

It can be seen that the tin of the chip has melted

8

00:00:37,766 --> 00:00:39,933

Remove the chip with tweezers

9

00:00:40,166 --> 00:00:43,100

This is how the SOP chip is disassembled

10

00:00:43,466 --> 00:00:47,300

Let's take a look at the method of soldering the SOP chip next.

11

00:00:47,866 --> 00:00:53,200

Still the same, we first use the air gun to continuously heat the pad of the chip

12

00:00:54,066 --> 00:00:58,200

Observe the tin melting on the pad while heating

13

00:00:58,800 --> 00:01:03,066

After the tin on the pad melts, place the chip on the pad

14

00:01:03,300 --> 00:01:07,700

After the tin on the pad is connected to the chip, remove the air gun

15

00:01:07,933 --> 00:01:10,400

Wait for the tin to solidify before removing the tweezers

16

00:01:11,266 --> 00:01:15,233

If you feel that the soldering of the chip is not very good, or the soldering is crooked,

17

00:01:15,700 --> 00:01:17,833

you can add a little solder oil to the pins

18

00:01:18,500 --> 00:01:20,566

Then use the air gun to heat the chip once

19

00:01:22,933 --> 00:01:26,033

Observe the melting of the pin tin while heating

20

00:01:27,066 --> 00:01:29,933

After the tin melts again, the chip is soldered.

21

00:01:32,066 --> 00:01:37,033

After the chip is soldered, check the soldering situation to prevent false soldering

22

00:01:38,866 --> 00:01:43,200

Use tweezers to scrape each pin to make sure they are all soldered

23

00:01:44,100 --> 00:01:49,066

If we find that there is a lead angle of virtual soldering, we can use a soldering iron to mend the tin

24

00:01:50,100 --> 00:01:53,466

If there are no false welds, then the welding is complete
