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