00:00:15.200 --> 00:00:20.680
Behold the almighty soldering iron. It fuses

2
00:00:20.680 --> 00:00:24.940
metal. Combines conductors. So powerful.

3
00:00:43.960 --> 00:00:49.160
Hey guys, excuse me, I'm just coming in here, I'm going to do some soldering.

4
00:00:49.260 --> 00:00:52.760
Did she just, oh my gosh, she just picked it up.

5
00:00:52.760 --> 00:00:54.700
Like the sword from the stone.

6
00:00:55.020 --> 00:00:56.640
She is the chosen one.

7
00:00:56.960 --> 00:01:01.100
You guys, a soldering iron isn't magic, but it is pretty powerful.

8
00:01:01.440 --> 00:01:06.680
It uses the power of heat to bond components together with material called solder.

9
00:01:07.200 --> 00:01:10.520
Well, it must use a lot of heating power then.

10
00:01:10.820 --> 00:01:14.700
That's right, Ruby. This soldering iron uses 65 watts of power.

11
00:01:14.880 --> 00:01:17.720
And with great power comes great responsibility.

12
00:01:18.420 --> 00:01:21.520
And what exactly does that mean?

13
00:01:21.520 --> 00:01:26.620
It means that you have to be very careful when soldering and follow a few simple rules.

14
00:01:26.900 --> 00:01:28.020
What sort of rules?

15
00:01:28.800 --> 00:01:32.080
For starters, soldering irons are not toys.

16
00:01:32.400 --> 00:01:36.440
They're specialized tools, and they get very hot very fast,

17
00:01:36.600 --> 00:01:39.580
and you can't tell how hot they are just by looking at them.

18
00:01:40.300 --> 00:01:43.940
Oh, like an electric stove. They can be dangerous.

19
00:01:45.100 --> 00:01:49.060
Exactly. It's easy to burn yourself if you aren't sure what you're doing.

20
00:01:49.060 --> 00:01:53.480
Young people and beginners shouldn't be using a soldering iron without an

21
00:01:53.480 --> 00:01:58.940
experienced adult around. So how dost thou wield such a

22
00:01:58.940 --> 00:02:01.640
dangerous tool? First up,

23
00:02:01.940 --> 00:02:04.880
let's start with some basic safety gear. Such as?

24
00:02:09.880 --> 00:02:14.640
When solder is heated up quickly by a soldering iron, it can sometimes spit

25
00:02:14.640 --> 00:02:19.040
little drops of hot liquid called flux. That's why it's important to wear a

26
00:02:19.040 --> 00:02:22.900
good pair of safety glasses. Gross, no spitting.

27
00:02:29.780 --> 00:02:34.060
When solder melts, it releases the smoke that you definitely don't want to breathe.

28
00:02:34.440 --> 00:02:40.360
A fume extractor like this one uses a fan to suck that smoke into a filter so

29
00:02:40.360 --> 00:02:41.220
you have clean,

30
00:02:41.440 --> 00:02:47.200
fresh air to breathe. Ah, that's much better.

31
00:02:53.500 --> 00:02:58.460
You should only hold the soldering iron by the handle, and never touch the heating

32
00:02:58.460 --> 00:02:58.900
element.

33
00:02:59.420 --> 00:03:02.360
Yikes! No way! Total Burnsville!

34
00:03:02.700 --> 00:03:06.360
That's right, and because it's so hot, you can't just put down a soldering iron

35
00:03:06.360 --> 00:03:06.800
anywhere.

36
00:03:07.200 --> 00:03:09.600
You need to have a stand that can withstand the heat.

37
00:03:10.200 --> 00:03:11.760
Oh, like this one?

38
00:03:12.020 --> 00:03:16.120
Exactly! This soldering iron stand is made out of metal, so it doesn't burn,

39
00:03:16.120 --> 00:03:19.600
and it has a wide, flat base so it won't tip over.

40
00:03:19.920 --> 00:03:24.300
So a stand holds the iron, what holds the thing you're soldering?

41
00:03:30.740 --> 00:03:32.340
That's where a vise comes in.

42
00:03:32.680 --> 00:03:36.640
This vise is designed to hold small circuit boards securely during soldering.

43
00:03:37.020 --> 00:03:41.740
All you do is slide the circuit board in and then tighten the jaws to hold it in place.

44
00:03:41.880 --> 00:03:42.960
Then you're ready to start working.

45
00:03:42.960 --> 00:03:46.740
What if you're soldering really big circuit boards?

46
00:03:47.040 --> 00:03:50.900
Well, for those, we've got really big vises for big boards.

47
00:03:51.200 --> 00:03:53.400
Whoa, it's a super vise.

48
00:03:54.440 --> 00:04:00.360
So, once you have all the important safety gear taken care of, how do you start

49
00:04:00.360 --> 00:04:01.020
soldering?

50
00:04:01.280 --> 00:04:05.040
Well, now that we've got everything set up with our safety and our gear, doing the

51
00:04:05.040 --> 00:04:06.640
actual soldering is pretty simple.

52
00:04:07.680 --> 00:04:09.960
Step one, turn on the iron.

53
00:04:10.860 --> 00:04:12.600
Now, wait for it to heat up.

54
00:04:13.340 --> 00:04:18.400
While it's heating up, place the component you want to solder onto the PCB.

55
00:04:19.620 --> 00:04:22.020
Place the PCB in your vise.

56
00:04:25.200 --> 00:04:29.660
Place the hot iron tip between the component lead and solder pad.

57
00:04:30.180 --> 00:04:33.240
Feed solder into joint and voila!

58
00:04:35.960 --> 00:04:37.600
It's a miracle!

59
00:04:38.480 --> 00:04:40.340
Amazing! Wunderbar!

60
00:04:41.020 --> 00:04:46.980
Then clean the iron's tip using some brass wool or a damp sponge and place it

61
00:04:46.980 --> 00:04:48.000
back in the holder.

62
00:04:48.500 --> 00:04:52.880
Last but not least, don't forget to turn off your soldering iron.

63
00:04:53.560 --> 00:04:54.920
You make it look easy.

64
00:04:55.200 --> 00:04:59.520
Thanks. It's not that hard, but it does take a little bit of practice to get good at.

65
00:04:59.820 --> 00:05:04.260
Now remember, nobody here should be using the soldering iron without me here for

66
00:05:04.260 --> 00:05:04.760
supervision.

67
00:05:05.300 --> 00:05:06.600
Yeah, no sweat.

68
00:05:08.820 --> 00:05:14.340
well since you're here maybe you could help us with this

69
00:05:14.340 --> 00:05:17.360
project it's not too complicated

70
00:05:20.160 --> 00:05:25.080
yeah it should only take a few hours oh no what have i done
