The new TerraGreen (RF/MW) is specifically engineered for high performance applications. It is a lead-free assembly PCB laminate. Isola TerraGreen (RF/MW) is a Radiofrequency and microwave laminate. Also, this laminate uses a short lamination cycle. Isola TerraGreen (RF/MW) PCB material features no plasma. It reduces drilling costs and has a long shelf life.
Also, digital signaling needs high frequency design to maintain signal integrity. Crosstalk and impedance mismatch are very crucial. Servers, routers, and power amplifiers are examples of applications that demand high performance boards. Most times, RF/microwave circuit boards feature a few layers. Materials ideal for RF/microwave may not be ideal for high speed applications. This is because of the processing considerations.
Furthermore, the Isola TerraGreen (RF/MW) maintains a stable Dk between -55°C and 125°C. This material is ideal for high speed digital backplanes. Also, it is compatible with FR-4 laminates for hybrid designs.
