High frequency laminates are used in PCBs that require a low dissipation factor (Df) and very stable dielectric constant (Dk). The main applications are radio PCBs, antennas, filters, power amplifiers and high speed digital PCBs.
Aspocomp has long experience of working with special RF and high speed materials. We have the best special material production knowhow in the case of materials from laminate companies like Isola, Panasonic, Rogers, ShengYi and Taconic, but we also have experience of many other materials.
Dk (1GHZ) values for high frequency/high speed digital materials vary between 3.1 – 3.9 depending on material, and the Df (1GHz) of materials starts from 0.002 range. Some high speed materials are also used for HDI/anylayer HDI applications – contact us to check suitable variants for your application.
We also have wide experience of working with different levels of RF materials including PTFEs. RF materials are used in various applications starting from simple 2L boards to metalback PCBs and complex multilayer Hybrid or Inlay PCBs. We also work with complex RF PCBs with high reliability for security, defense and aerospace applications.
