RO3000® high frequency circuit materials are ceramic-filled
PTFE composites intended for use in commercial microwave and RF applications. This family of products was designed to offer exceptional electrical and mechanical stability at competitive prices.RO3000 series laminates are ceramic-filled
PTFE based circuit materials with mechanical properties that are consistent regardless of the dielectric constant selected. This allows the designer to develop multi-layer board designs that use different dielectric constant materials for individual layers, without encountering warpage or reliability problems.
RO3000 materials exhibit a coefficient of thermal expansion (CTE) in the X and Y axis of 17 ppm/°C. 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/°C, which provides exceptional plated through-hole reliability, even in severe thermal environments. The dielectric constant versus temperature for RO3003™ and RO3035™ materials is very stable.
RO3000 series laminates can be fabricated into printed circuit boards using standard
PTFE PCB processing techniques, with minor modifications as described in the application note “Fabrication Guidelines for RO3000Series
High Frequency PCB Materials.

Production difficulties
Because PTFE PCB is flexible and prone to crease during manufacturing, it is necessary to handle it with care during production and put it in special vessels; in addition, PTFE PCB needs plasma treatment before PTH process after drilling.
