What Is Isola IS680 PCB Laminate Materials?

Isola IS680 is a type of PCB (Printed Circuit Board) laminate material. It is specifically designed for use in RF (Radio Frequency) and microwave applications. PCB laminates are used as the base material for creating circuit boards that house electronic components.

IS680 is known for its exceptional electrical properties and stability over a broad frequency and temperature range. It exhibits a stable dielectric constant (Dk) between -55°C and +125°C, making it suitable for use in various temperature environments. It maintains its electrical performance even at high frequencies, such as W-band frequencies.

One of the key advantages of IS680 is its low dissipation factor (Df), which refers to the amount of energy lost as heat when signals pass through the material. The low Df of IS680 makes it an attractive and cost-effective alternative to other commonly used microwave laminate materials, such as PTFE (Polytetrafluoroethylene).
