Oh, hey, this is what I do for a living.
There’s a lot of math and formulas to learn if you’re designing electronics, but just doing assembly requires a lot less math. There’s a lot of tools to help with the math, though, so it usually isn’t too daunting. When actually doing the work, you’ll need to read through a lot of documentation, like spec sheets, to design your stuff to work with their stuff. When it comes to assembly, you’ll need to know a lot of rules and be able to follow drawings. You’ll need to learn about electromagnetic interference and how to limit it, how to use anti-static equipment, multimeters, hipot testers, how to solder, and so on. Its a lot, but you don’t usually have to do everything at once, so it is managable. Many things, like soldering, takes practice and a steady hand.
Feel free to message me if you have any specific questions!
Hello! Always nice to meet electronics guys.
