Background: Printed Circuit Boards (PCBs) are fundamental components in modern electronic devices, serving as the backbone that supports and electrically connects various electronic components. A PCB consists of multiple layers of conductive pathways embedded in a non-conductive substrate material. These pathways are etched from copper, enabling the circuit to function effectively.

Importance of Topic: The substrate material of a PCB is crucial as it influences the board’s electrical performance, mechanical stability, and thermal management. High-quality substrates ensure optimal electrical insulation, minimal signal interference, and reliable performance under various environmental conditions. Poorly chosen substrates can lead to circuit failures, reduced lifespan, and overall inefficiency. Therefore, understanding different substrate materials and their properties is essential for designing reliable and high-performance PCBs, which are pivotal in ensuring the functionality and longevity of electronic devices.

A substrate is a foundational material or surface upon which other processes or substances interact. In electronics, substrates provide essential support for circuits, ensuring stability and functionality. They are crucial in determining the performance and reliability of electronic devices, such as printed circuit boards (PCBs) and integrated circuits (ICs). In biology, substrates serve as the surface for biochemical reactions or as the medium for organisms to grow and interact. They play a pivotal role in enzyme activity, nutrient absorption, and ecological systems.
