What are some key properties of Rogers laminates for high frequency PCBs?

Some key properties that make Rogers laminates like RO4000 and RT/duroid ideal for high frequency PCBs are:

  • Stable dielectric constant over wide frequency range
  • Low loss tangent and dissipation factor
  • Excellent dimensional stability
  • High thermal conductivity
  • Good CTE match with copper
  • Easy drillability and excellent plating adhesion

How are Rogers absorbers used for EMI shielding?

Rogers offers flexible and rigid absorbers that can absorb radiated EMI/RFI over a wide frequency range. These are used on enclosures, covers and ventilation panels to attenuate interference. Eccosorb FGM, SF and FS are flexible absorbers while Eccosorb VF tile absorbers provide rugged performance.

What are some applications of curamik ceramic substrates?

curamik ceramic substrates find use in high power and high temperature applications like:

  • IGBT power modules
  • Automotive power converters and inverters
  • Industrial motor drives
  • Wind and solar converters
