Material Selection Considerations

Semiconductor Materials:

• Silicon (Si): The most common material for integrated circuits.
• Germanium (Ge): Used in some specialized applications.
• Gallium Arsenide (GaAs), Gallium Nitride (GaN), Silicon Carbide (SiC): Used for high-frequency, high-power, or high-temperature applications.

Conductors:

• Copper (Cu): For wiring, PCB traces, and connectors due to its high conductivity.
• Aluminum (Al): For heat sinks and sometimes for power transmission.
• Gold (Au): For electrical contacts and connectors due to its excellent conductivity and corrosion resistance.

Insulators/Dielectrics:

• Plastics (e.g., PVC, Polycarbonate, ABS): For casings, wire insulation, and structural components.
• Ceramics: For high-temperature applications, resistors, and some capacitors.
• Fiberglass (e.g., FR-4): For PCB substrates.
• Rubber/Silicone: For seals, gaskets, and flexible insulation.

Magnetic Materials:

• Ferrites: For inductors and transformers.
• Iron Alloys: For transformer cores.

Resistive Materials:

• Carbon Film, Metal Film, Wirewound: For resistors.

Packaging Materials:

• Plastics: For device casings, often ABS, PC, or blends, chosen for aesthetics, durability, and flame retardancy.
• Metals (Aluminum, Steel): For robust casings, shielding, or heat dissipation.
• Glass: For displays, sensors.

Soldering Materials:

• Tin-Lead (Pb-Sn) or Lead-Free (e.g., Sn-Ag-Cu) Solders: For connecting components to PCBs.
