What is the difference between FR4 material and Rogers material?

What is the difference between FR4 material and Rogers material?

FR-4 material has a high Df or dissipation factor than Rogers material, suffering more signal loss. 4. In impedance stability, Rogers material has a wider range of Dk values than FR-4 material.

What is FR4 used for?

FR4 is rightly the most used material in PCB construction. Boards made from FR4 are strong, water resistant, and provide good insulation between copper layers that minimizes interference and supports good signal integrity.

Are PCBs made of FR4?

FR4 is the most commonly used material in PCB manufacturing. These boards are durable, water-resistant, and provide excellent insulation between copper layers, reducing interference and ensuring signal integrity.

What is the thickness of FR4?

Standard FR4 Thickness from 0.2 to 3.2 mm.

What is FR4 material made of?

FR4 is a class of printed circuit board base material made from a flame retardant epoxy resin and glass fabric composite. FR stands for flame retardant and meets the requirements of UL94V-0. FR4 has good adhesion to copper foil and has minimal water absorption, making it very suitable for standard applications.

What is Rogers PCB?

Rogers PCB is a type of high-frequency board that raw material is produced by Rogers company. It is different from the conventional PCB board—epoxy resin (FR4). It has no glass fiber in the middle and uses a ceramic base as the high-frequency material. Rogers has superior dielectric constant and temperature stability.

Why we use FR4 substrate?

FR4 sheets are electrical insulators with high dielectric strength. They also feature a high strength-to-weight ratio and are lightweight and resistant to moisture. Add this to their relative temperature resistance, and FR4 material can perform well in most environmental conditions.

What is FR4 made?

Is FR4 brittle?

At low temperatures (below Tg and in the glassy region), the material will be rigid and somewhat brittle.
