===== Basic Soldering Lesson 4 =====
==Description==
'''Soldering''' is a process in which two or more items (usually metal) are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Soldering differs from welding in that soldering does not involve melting the work pieces. In brazing, the filler metal melts at a higher temperature, but the work piece metal does not melt. In the past, nearly all solders contained lead, but environmental and health concerns have increasingly dictated use of lead-free solder for electronics and plumbing purposes.
Here is an example of this piece of equipment being used.

==Training==
====Operation====
The Soldering Iron is an amazing tool that allows us to construct circuits with sturdy connections between components. The detailed steps to do this can be found in videos on the Description section.
====Demonstration====
Before using a Soldering Station, students will need to read some documentation, watch some videos, and pass a quiz on Canvas. Upon completion, students will be given the following PCB and components to assemble the circuit below. Upon completion, they will have the PCB Lab volunteers assess their work and confirm operation. The deliverable will include a video of the working device and a crisp "Thumbs Up" from the PCB Lab Volunteer to assure that the student successfully completed the task.

====General Procedure====
# First things first, you need to learn how to use the soldering irons! Soldering is not difficult, but understanding some basic concepts will go a long way toward a successful experience. As part of your training, you will need to read some documentation and watch some videos.
# After scouring the web for examples of soldering training, we really liked the lessons captured in the [https://www.youtube.com/playlist?list=PL926EC0F1F93C1837 PACE] series, despite the fact that they were filmed in the 80's. These videos are well produced (for something possibly older than your parents) and have a lot of good information. The quizzable information is in the very first, fifth, and sixth videos, but the other videos have great examples of good and bad soldering joints. Another more modern video from [https://www.youtube.com/watch?v=ZwU9SqO0udU Beauty and the Bolt] is also insightful. This video is a little more modern, and a good resource, but not as technically interesting. It talks a bit about desoldering as well as soldering wires together and how to use heat shrink and electrical tape. A more modern series is available from [https://www.howcast.com/guides/930-how-to-solder Howcast]. It wouldn't hurt at all to watch this series, but we will just focus on a couple for the quiz. Finally, there is an official training video from the [[Maker Hub]] that is tailored to our specific space and equipment. This video will give you the information you need to perform the live solder demonstration required for your soldering certification.
# This nostalgic set of [https://www.youtube.com/playlist?list=PL926EC0F1F93C1837 videos] from PACE are quite old, but surprisingly still quite relevant. The style makes you think that you will be getting ready to watch an old Disney cartoon - you aren't. Don't get disappointed.

We suspect that you can manage without that. Here are some key ideas that you should watch for:

#
# Acquire a soldering station. For this procedure, this particular station will be referenced, the Weller WES51.[[File:...solderingiron.png|none|thumb|300x300px]]
# You can power it on using the switch on the left and control the temperature in °F using the temperature knob on the right. 650-750 °F is a good temperature range to keep it at. When the light is solid green, the iron is not heated up yet. When it is heated to the temperature you set on the temperature knob, it will start blinking green.
# Before you begin using the soldering iron, wet the sponge! Take it to a sink and drench that boi. This is used to clean the soldering iron continually during use. If you don't make it wet, it will burn up the sponge and smell/look gross, and it won't clean the soldering iron.
# Now you're ready to use the soldering iron! Refer to the videos in times of doubt.
# Don't forget to complete that video checking off your board!
==Safety==
# Always wear safety glasses when you are cutting wires or anything else at the electronics workstation. If other people are nearby, ask them to wear safety glasses or step away briefly.
# Angle your wire cuts down into the table or cover them with your free hand to block the projectile.
# Soldering irons can get up to 1000 °F. Do not touch the tip of the soldering iron; it is extremely hot. If you get burned, run cold water over the burned area for several minutes to reduce inflammation and the potential for blistering.
# Wires and components can also become extremely hot from soldering. Use the available helping hands, and allow the wires/components to cool before touching.
# Always return the soldering iron to its stand when not in use. Never lay it directly on the workbench.
# Ensure you have adequate ventilation when soldering. Use the available fume extractors.
# Turn off the soldering iron when it is not in use.
# If you start an electrical fire, use a fire extinguisher to put it out. NEVER use water to put out an electrical fire.
# Keep liquids away from the electronics workstation.

==== Demonstration ====
==Troubleshooting==
There are two things in particular that could keep you from successfully soldering: an untinned tip and a loose tip. If the tip is not shiny silver, then place a little solder on the tip and wipe it on the sponge. Some soldering irons allow there tips to be replaced for the sake of having different shapes. If the iron is not heating up and you are using this type of iron, it is possible that the tip is not inserted into the iron fully. To fix this, grab some pliers (so you don't burn your hands), grip the shaft and push it in fully. After you have finished soldering, you might check the electrical continuity of your solder joint with a [[Electronics Workstation | DVM]].
==Maintenance==
====General maintenance====
The maintenance for the soldering iron generally consists of keeping the soldering station cleaned, stocked, and the iron tinned.
