Home >> Advanced Connectivity Solutions >> Products >> RO4000® Laminates >> RO4700™ Antenna Grade Laminates
RO4700™ antenna grade laminates are fully compatible with conventional FR-4 and high temperature lead-free solder processing and do not require the special treatment needed on traditional PTFE-based laminates for plated through hole preparation. An affordable alternative to conventional PTFE-based antenna materials it allows, designers to optimize cost and performance.
The resin systems of RO4700 dielectric materials provide the necessary properties for ideal antenna performance. The coefficients of thermal expansion (CTEs) in both the X and Y directions are similar to that of copper. The good CTE match reduces stresses in the printed circuit board antenna. The typical glass transition temperature of RO4700 materials exceeds 280°C (536°F), leading to a low Z-axis CTE and excellent plated through hole reliability.
