What is Rogers PCB versus FR4?

Rogers PCB have a low loss, low dielectric constant, good thermal performance consistency, stable chemical properties, and almost no moisture absorption.

  1. high temperature resistance – use working temperature up to 250 °C
  2. low temperature resistance – it can maintain 5% elongation even if the temperature drops to -196 ° C.
  3. Corrosion resistance – shows inertness against strong acid and alkali, water and various organic solvents
  4. Excellent weather resistance – the best aging life in plastics
  5. High lubrication – the lowest friction coefficient in solid materials
  6. Non-adhesive – is the smallest surface tension in solid materials and does not adhere to any substance. The friction coefficient is very small.
  7. Non-toxic – commonly used in physiologically inert, long-term implantation of artificial blood vessels and organs
  8. Good electrical properties – Polytetrafluoroethylene has low dielectric constant and dielectric loss over a wide frequency range, high breakdown voltage, and a high arc resistance.
  9. Rogers material is more expensive than FR4 material
  10. Rogers material has a higher dissipation factor than than FR4
  11. Rogers material has higher impedance stability, and offers a wider range of dielectric constant options than FR-4 material.
  12. Rogers material has a less variation in larger temperature swings compared to FR-4 material.
