To help you understand the process of electronics recycling in Mississauga, let’s learn first the different components that make up the printed circuit board assembly (PCBA). Furthermore, the right PCB assembler will make sure that even if you are into assembly-only business, all the materials, processes and tests are carefully selected and meticulously performed.
Circuit board assembly is different from manufacturing a circuit board which involves the different layers like the substrate, solder mask and silkscreen. After the circuit board is completed, the PCBA process now takes place. This involves adding the electronic components such as resistors, transistors and capacitors to the green board using soldering materials and/or soldering equipment.
Following are the parts and components recyclers look for when processing them at an electronics recycling Mississauga facility:
Printed Circuit Board
A printed circuit board looks consists of layers made of different materials that are joined together with heat and adhesive so that it becomes a single compact object. These layers include the substrate, copper trace, solder mask and silkscreen that are placed one on top of another.
Electronic Components
Each electronic component that is added on to the printed circuit board has unique qualities and functions perfect for its intended purpose. The following are some of the electronic components of a PCBA commonly seen at electronics recycling Mississauga centers:
- Resistors control the amount of electric current that passes through them.
- Transistors both conduct and insulate and can act as a switch and an amplifier.
- Capacitors store electrical energy and give this energy again to the circuit when needed.
- Inductors store energy in a magnetic field when an electric current pass through them.
- Diodes allow current to pass easily in one direction but restricts current from flowing in the opposite direction.
Soldering Materials
Soldering joins the electronic components to the printed circuit board with the help of soldering materials. Soldering materials in forms of powder, wire or preforms have low melting points and are usually a mix of tin and lead.
Flux
Fluxes are used in combination with soldering materials which is usually a mixture of 50/50 ratio. They act as temporary adhesives and holds the components until the soldering process melts the solder and joins the parts together. Furthermore, they also clean and remove any oxides and impurities from the circuit board to avoid poor flow of electricity through the circuit.
SMT (Surface Mount Technology) Placement Equipment
SMT placement equipment is a type of robotic machine used to place surface-mount devices (SMDs) to the printed circuit board. It is highly valued in many PCB assembly companies where speed and high precision are crucial especially when placing different electronic components like resistors, capacitors and integrated circuits on printed circuit boards.
Once the PCB is nearing the end of its life cycle, it is time to begin the electronics recycling process. Do you have old PCBs and looking for electronics recycling in Mississauga?
