📦 2. Types of Component Packages
Component packaging defines the form factor, mounting method, and electrical connections. Choosing the correct package is vital for PCB layout and assembly.
🧱 Through-Hole Packages (THT)
- Mounted by inserting pins into drilled PCB holes.
- Examples:
- DIP (Dual Inline Package)
- TO-220 (for power semiconductors)
- TO-92 (for transistors)
🧲 Surface Mount Device (SMD) Packages
- Smaller, mounted directly onto PCB surface.
- Examples:
- SOT (Small Outline Transistor)
- QFP (Quad Flat Package)
- SOP (Small Outline Package)
- 0805, 0603 (for resistors/capacitors)
🧬 Advanced Packages
- Used for compact and high-performance applications.
- Examples:
- BGA (Ball Grid Array)
- LGA (Land Grid Array)
- CSP (Chip Scale Package)
🔩 Connector & Module Packages
- USB connectors, RF modules, Arduino boards
Each package has implications for cost, size, heat dissipation, and automation in manufacturing.
