Rogers PCB Made on RO3035 10mil 0.254mm DK3.5 with Immersion Gold for Patch Antenna for Wireless Communications
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Rogers RO3035 high frequency circuit materials are ceramic-filled PTFE composites intended for use in commercial microwave and RF applications. It was designed to offer exceptional electrical and mechanical stability at competitive prices. The mechanical properties are consistent. This allows the designer to develop multi-layer board designs without encountering warpages or reliability problems. RO3035 materials exhibit a coefficient of thermal expansion(CTE) in the X and Y axis of 17 ppm/℃. This expansion coefficient is matched to that of copper, which allows the material to exhibit excellent dimensional stability, with typical etch shrinkage, after etch and bake, of less than 0.5 mils per inch. The Z-axis CTE is 24 ppm/℃, which provides exceptional plated through-hole reliability, even in severe environments.
Typical applications:
1) Automotive radar
2) Datalink on cable systems
3) Global positioning satellite antennas
4) Power amplifiers and antennas
