Printed Circuit Boards (PCBs) are the backbone of modern electronics, and selecting the right PCB materials is crucial for performance, durability, and cost-effectiveness. The substrate used in PCB manufacturing determines electrical properties, thermal resistance, and mechanical strength. This guide explores the different types of PCB materials, their properties, and how to choose the best one for your application.
1. Introduction to PCB Materials
PCB materials serve as the foundation for electronic circuits, providing insulation, support, and connectivity. The choice of material impacts signal integrity, heat dissipation, and overall reliability. Common PCB substrate materials include:
- FR-4
- Polyimide
