[00:00:15.200] Behold the almighty soldering iron. It fuses
[00:00:20.680] metal. Combines conductors. So powerful.
[00:00:43.960] Hey guys, excuse me, I'm just coming in here, I'm going to do some soldering.
[00:00:49.260] Did she just, oh my gosh, she just picked it up.
[00:00:52.760] Like the sword from the stone.
[00:00:55.020] She is the chosen one.
[00:00:56.960] You guys, a soldering iron isn't magic, but it is pretty powerful.
[00:01:01.440] It uses the power of heat to bond components together with material called solder.
[00:01:07.200] Well, it must use a lot of heating power then.
[00:01:10.820] That's right, Ruby. This soldering iron uses 65 watts of power.
[00:01:14.880] And with great power comes great responsibility.
[00:01:18.420] And what exactly does that mean?
[00:01:21.520] It means that you have to be very careful when soldering and follow a few simple rules.
[00:01:26.900] What sort of rules?
[00:01:28.800] For starters, soldering irons are not toys.
[00:01:32.400] They're specialized tools, and they get very hot very fast,
[00:01:36.600] and you can't tell how hot they are just by looking at them.
[00:01:40.300] Oh, like an electric stove. They can be dangerous.
[00:01:45.100] Exactly. It's easy to burn yourself if you aren't sure what you're doing.
[00:01:49.060] Young people and beginners shouldn't be using a soldering iron without an
[00:01:53.480] experienced adult around. So how dost thou wield such a
[00:01:58.940] dangerous tool? First up,
[00:02:01.940] let's start with some basic safety gear. Such as?
[00:02:09.880] When solder is heated up quickly by a soldering iron, it can sometimes spit
[00:02:14.640] little drops of hot liquid called flux. That's why it's important to wear a
[00:02:19.040] good pair of safety glasses. Gross, no spitting.
[00:02:29.780] When solder melts, it releases the smoke that you definitely don't want to breathe.
[00:02:34.440] A fume extractor like this one uses a fan to suck that smoke into a filter so
[00:02:40.360] you have clean,
[00:02:41.440] fresh air to breathe. Ah, that's much better.
[00:02:53.500] You should only hold the soldering iron by the handle, and never touch the heating
[00:02:58.460] element.
[00:02:59.420] Yikes! No way! Total Burnsville!
[00:03:02.700] That's right, and because it's so hot, you can't just put down a soldering iron
[00:03:06.360] anywhere.
[00:03:07.200] You need to have a stand that can withstand the heat.
[00:03:10.200] Oh, like this one?
[00:03:12.020] Exactly! This soldering iron stand is made out of metal, so it doesn't burn,
[00:03:16.120] and it has a wide, flat base so it won't tip over.
[00:03:19.920] So a stand holds the iron, what holds the thing you're soldering?
[00:03:30.740] That's where a vise comes in.
[00:03:32.680] This vise is designed to hold small circuit boards securely during soldering.
[00:03:37.020] All you do is slide the circuit board in and then tighten the jaws to hold it in place.
[00:03:41.880] Then you're ready to start working.
[00:03:42.960] What if you're soldering really big circuit boards?
[00:03:47.040] Well, for those, we've got really big vises for big boards.
[00:03:51.200] Whoa, it's a super vise.
[00:03:54.440] So, once you have all the important safety gear taken care of, how do you start
[00:04:00.360] soldering?
[00:04:01.280] Well, now that we've got everything set up with our safety and our gear, doing the
[00:04:05.040] actual soldering is pretty simple.
[00:04:07.680] Step one, turn on the iron.
[00:04:10.860] Now, wait for it to heat up.
[00:04:13.340] While it's heating up, place the component you want to solder onto the PCB.
[00:04:19.620] Place the PCB in your vise.
[00:04:25.200] Place the hot iron tip between the component lead and solder pad.
[00:04:30.180] Feed solder into joint and voila!
[00:04:35.960] It's a miracle!
[00:04:38.480] Amazing! Wunderbar!
[00:04:41.020] Then clean the iron's tip using some brass wool or a damp sponge and place it
[00:04:46.980] back in the holder.
[00:04:48.500] Last but not least, don't forget to turn off your soldering iron.
[00:04:53.560] You make it look easy.
[00:04:55.200] Thanks. It's not that hard, but it does take a little bit of practice to get good at.
[00:04:59.820] Now remember, nobody here should be using the soldering iron without me here for
[00:05:04.260] supervision.
[00:05:05.300] Yeah, no sweat.
[00:05:08.820] well since you're here maybe you could help us with this
[00:05:14.340] project it's not too complicated
[00:05:20.160] yeah it should only take a few hours oh no what have i done
