What is Rogers PCB?

High-frequency PCB material is a hard and dense material, which can be used to manufacture printed circuit boards. The board contains epoxy resin core, copper plating and aluminum. The surface is coated with a layer of aluminum. It has good size and advantages in thermal expansion coefficient, and can effectively control temperature stress to ensure the stability of component performance. Can be widely used in high-frequency power distribution and CPU, switches, connectors and other circuit boards. It is most commonly used in radio frequency.

The pcb board is assembled because it is sensitive to electromagnetic (EM) waves (usually in the radio spectrum). This helps to reduce the interference caused by other high-frequency devices, such as radios, televisions and mobile phones.

PCB material also has excellent dielectric integrity and is specially designed for high-performance RF circuit boards. This material has excellent electrical and thermal stability, which makes it an ideal choice for exposure to extreme temperature and vibration.

Rogers PCB material thickness

Rogers PCB materials can be manufactured in various thicknesses and sizes, and can be customized according to your specific needs. Two standard sizes include:

Standard thickness: This kind of high-frequency board is very suitable for applications with small gap between conductor and trace. It has good electrical performance, especially at higher frequencies. This type of plate also has better thermal performance than thin plate, which makes it very suitable for applications where heat dissipation is very important.

Thin plate: The electrical loss of thin plates is lower than the standard thickness, because their surface area per unit area is increased, so their resistance is lower. They also have better electrostatic discharge (ESD) protection than standard thickness circuit boards, because they provide greater resistance during ESD.

The standard dielectric in flexible circuit is 0.00 1-

0.002"。 This relatively thin layer of material separates the copper traces and components in the flexible printed circuit board. The thickness of this layer determines how easy it is for the material to bend and bend without destroying internal connections or causing short circuits.

The most commonly used materials for making this dielectric are polyester and polyamide materials. They are usually coated with a conductive material, such as silver, aluminum or copper, as electrical conductors between the circuit board and the traces on the surface of the components.
