How do you salvage useful components from electronic waste?

2 Identifying components

The next step is to identify the components that you want to salvage from the e-waste. Depending on the type and model of the device, you may find different kinds of parts, such as resistors, capacitors, transistors, diodes, LEDs, switches, potentiometers, speakers, motors, sensors, microcontrollers, memory chips, and more. Some of these components are easy to recognize by their shape, color, or markings, while others may require some research or testing. You can use online databases, datasheets, schematics, or forums to find out more about the components and their specifications.

3 Removing components

Once you have identified the components that you want to salvage, you need to remove them from the circuit board or the device. Desoldering, cutting, and prying are three of the most common methods for removing components, depending on their type and how they are attached. Desoldering involves heating up the solder joints that connect the component to the board and using a solder sucker or a desoldering braid to remove the molten solder, and is suitable for through-hole components and some surface-mount components. Cutting involves cutting the leads or pins of the component with a wire cutter or a knife, and is suitable for components that are not soldered or that have long leads or pins. Lastly, prying involves using a flat-head screwdriver or a pry tool to gently lift the component from the board or device, and is suitable for components that are glued or clipped.

4 Testing components

After you have removed the components, you need to test them to make sure they are still functional and within their specifications. You can use a multimeter to measure the resistance, capacitance, voltage, current, or continuity of the components. You can also use a breadboard, a battery, and some wires to create a simple circuit and test the components with a LED, a buzzer, or a speaker. You can also use an Arduino or a Raspberry Pi to program and test the components with a computer.

5 Storing components

The final step is to store the components in a safe and organized way. You can use plastic containers, ziplock bags, pill boxes, or foam boards to sort and label the components by their type, value, or function. You can also use anti-static bags or boxes to protect the components from electrostatic discharge. You can also use a magnifying glass, a tweezers, or a pen to handle the components carefully and avoid damaging them.
