Arlon-MED

產品說明

Arlon 25N and 25FR are woven fiberglass reinforced, ceramic-filled composite materials engineered for use in microwave and RF multilayer printed circuit boards. Combining a non-polar thermoset resin system with a controlled-expansion ceramic filler, 25N and 25FR offer low dielectric constant and loss combined with a low Thermal Coefficient of Dielectric Constant (TCEr) for signal stability over a wide ambient temperature range.

Designed for use in multilayer packages, 25N and 25FR offer prepregs that are identical in chemical composition and physical properties with their copper clad laminates for a completely homogeneous finished package for optimal signal integrity.

The low dielectric constant (Er) and loss properties, low thermal coefficient of dielectric constant (TCEr), and excellent physical stability characteristics offered by 25N and 25FR materials make them ideal for wireless and digital applications, such as cellular telephones, down converters, low noise amplifiers, antennas and other advanced des ign circuits.

Processing for 25N and 25FR materials is consistent with processing for standard high temperature thermoset based printed circuit board
substrates.
