Introduction
In the heart of every electronic device lies a complex system of chips, circuits, and connections. But none of these would function reliably without one crucial component: electronic packaging. As the silent enabler of device integrity, thermal control, and signal routing, electronic packaging plays a vital role in ensuring the durability, functionality, and miniaturization of modern electronics.

What is Electronic Packaging?

Electronic packaging refers to the enclosure and interconnection of semiconductor devices (like ICs and transistors) and other electronic components. It protects sensitive elements from physical damage, environmental stress, and electromagnetic interference, while also providing electrical connections and thermal pathways.

Key Functions of Electronic Packaging

• 🛡️ Protection – Shields components from moisture, dust, heat, vibration, and corrosive agents

• 🔌 Electrical Connection – Facilitates connectivity between chips and circuit boards

• ❄️ Thermal Management – Dissipates heat to maintain device performance

• 📏 Form Factor Optimization – Supports miniaturization and portability of devices

• ⚡ Signal Integrity – Maintains high-speed signal performance with minimal loss or interference

Types of Electronic Packaging

Materials Used in Electronic Packaging

• Substrates – Silicon, ceramic, FR-4, BT resin
