The Isola GETEK Low Dk/Df Laminate and Prepreg materials are engineered to meet the requirements of high-speed, low-loss Printed Wiring Board (PWB) applications. These materials feature a low dielectric constant (Dk) and low dissipation factor (Df), which are crucial for maintaining signal integrity in high-speed electronic circuits. The laminate and prepreg are made using a functionalized Polyphenylene Oxide (PPO)/epoxy resin, reinforced with electrical grade (E-glass) glass fabric, ensuring robust mechanical and thermal properties. This combination offers a superior performance over traditional FR-4 materials, particularly in terms of thermal stability, with a glass transition temperature (Tg) of 180°C and a decomposition temperature (Td) of 345°C.

When designing a PCB stackup using GETEK materials, the following considerations should be taken into account:

• Thermal Management: The high Tg and Td values make GETEK suitable for applications requiring high thermal reliability. This is particularly important in densely packed circuits or high-power applications where thermal management is critical.
• Signal Integrity: With a Dk of 3.60 and a Df of 0.009 at frequencies ranging from 50 MHz to 1 GHz, GETEK materials support increased signal speeds and provide better signal integrity, which is essential for high-speed data transmission applications.
• Processing Compatibility: GETEK materials are processed similarly to conventional FR-4, making them a good choice for manufacturers looking to switch to a higher performance material without significant changes to existing fabrication processes.

Additionally, the GETEK system includes features like UV blocking and AOI fluorescence, which enhance the throughput and accuracy during PCB fabrication and assembly. This material is also RoHS compliant, making it suitable for use in environments where hazardous substances are regulated. When ordering, GETEK materials are available in various forms including full size sheets or panels for laminates, and rolls or panel form for prepregs, with options for different copper weights and types.
