How To Build Electronic Circuits

So you want to build electronic circuits? Most likely, these are some custom circuits or DIY mods, and in most instances the best way to learn to build electronics is to start off by breaking them.

Taking an old electronic circuit board out of a piece of junk and removing the tiny components from the bottom of the board using a solder pump and hot soldering iron is easy and can be the best way to become familiar with the multilayer construction of electronic circuits which, for most beginners, is a critically difficult step. It also will help you learn the delicate task of soldering, which will either teach you to have a gentle hand or will teach you to destroy soldering irons and components, either way, you'll know.

To remove an electronic component, the widely agreed on best method is to build that part of the circuit up. A hard to melt area of solder can be melted more easily when already hot solder is added to it. Then once the solder pump sucks it up and that area is cleaned with alcohol, you can flip the used electronic circuit board over and insert your parts. By using a multimeter or by tracing the metal circuit connections from the back, you can figure out which holes on the board are connected to each other and where to insert your parts to build electronic circuit how you want.

Bending the metal leads on electronic circuit components is not recommended unless pliers are used gently or you have a backup part for when the leads break off. When the part is inserted, use a piece of electrical tape to affix it to the electronic circuit board so that you can flip it over and find the leads. Select a particular lead and heat it up slowly. By putting solder on the lead (not the hot iron) you can build electronic circuits bit by bit by connecting the parts in small steps.

If you are recycling parts, be sure to consistently test your electronic circuit frequently to make sure you connected the parts. An old electronic circuit board can lose its metal coated layers and connections if the soldering iron burns them off, or a sharp metal screwdriver slips and gouges through them. If you feel you've done everything correctly, but if the newly built electronic circuit doesn't levitate as intended, it’s usually a good bet to check and see if the metal layer of the board is still intact right around the edge of a hole. The alternative to using recycled parts to build electronic circuits is not nearly as cool or self-empowering. Custom printed electronic circuits are available but you may not want to share your super secret device plans.
