Depending on the e-waste, large circuits may be extracted and used to create other simpler electronic devices. The circuit board pictured above was removed carefully from a printer with all individual components still attached. While this particular circuit appears very intricate and complicated, each individual component is very valuable and could be removed safely and recycled for another project.

Examples of the components in a circuit board:
  • Resistors
  • Diodes
  • Transistors
  • Capacitors
  • Oscillators
With these components safely extracted out of the e-waste circuit board, examples of simplified experiments are:
  • Creating a light source using LED lights and a switch
  • Alarm system using buzzers and amplifiers

How to Remove Electronic Components from E-Waste Circuit Board

Soldering is a method of joining electrical components together. While solder, a low-melting alloy, is mainly used for "permanent" connection, there is a way to "de-solder". This method can be used for the recycling of resistors, diodes, transistors, capacitors, oscillators, etc. The process requires PATIENCE and CAUTION! The soldering tool is extremely hot as to melt the alloy and without proper attention towards it can cause severe burns. Another consideration to take in is the delicacy of the electronic components: their small sizes are more prone to damage and could easily be lost.
