Rogers RO4533 Material Introduction

Rogers RO4533 laminates are ceramic-filled, glass-reinforced hydrocarbon based material set, providing the controlled dielectric constant, low loss performance and excellent passive intermodulation response required for mobile infrastructure microstrip antenna applications. RO4533 laminates are fully compatible with conventional FR-4 and high temperature lead-free solder processing.

These laminates do not require special treatment needed on traditional PTFE-based laminates for plated through-hole preparation. It is an affordable alternative to more conventional PTFE antenna technologies, thus allowing designers to optimize the price and performance of their antennas. Moreover, RO4533 laminates are available halogen-free to meet the most stringent “green” standards. The typical glass transition temperature of RO4533 materials exceeds 280°C (536°F), leading to a low z-axis CTE and excellent plated through-hole reliability.
