Soldering

OpenSTEM does electronics soldering as part of our workshops with school classes and other groups. It has been, for instance, part of our robotics program.

Naturally some students pick up the technique quicker than others, but all tend to make a good effort. Results depend on focus (concentration), precision, a bit of dexterity and a steady hand, fine-motor control and coordination. Students are generally in the 9-12 age range when they do our soldering basics work.

We do soldering because it provides an awesome experience for students, an opportunity they don’t often get. For many, it amounts to an achievement that they feel really proud of. Some take a real liking to it.

Tools & Safety

Primary schools tend to have neither science labs nor related equipment of their own, so we bring all the necessary tools with us and take care of all the setup, instruction and guidance.  We have found it best to assemble and prepare our own soldering kits.

We use good quality but relatively simple soldering irons, because they are perfectly adequate for basic and even some more advanced work, and we feel that they can in some ways teach technique better. Also, students are unlikely to have particularly expensive equipment at their disposal elsewhere, so it’s not beneficial getting used to conveniences such as soldering stations. When students learn the basics this way, they will be able to use any tools.

Extra solid stands were chosen, with copper wire cleaning balls rather than the common wet sponge. We also have “helping hands” clips for gripping circuit boards and holding up components.

Prior to their first practical exercises, all students learn about the equipment, its proper handling and safe conduct. Students are required to use safety glasses when soldering, or when observing others soldering. Naturally, all our electrical tools and extension cords are regularly tested & tagged.

We work with a venue (school, library, etc) on the necessary paperwork such as risk assessment and management strategy. While not that many people will have used soldering irons, they are not intrinsically more dangerous than a stove, oven or clothes iron at home. It’s simply important to learn about the tools in a safe and calm manner, and get some practice at their use. We feel it very important to not let hurdles deter us from providing students with these fabulous opportunities and experiences.

At Home

Some students pick up soldering as part of a broader exploration of technical subjects. This is awesome, and while we don’t specifically push for it, we do actively encourage it if a student shows particular interest and asks questions about it. We can provide some advice to parents/carers on suitable tools and also offer our own soldering kits.
