4 Layer ENIG Rogers 4350 PCB

Features of Rogers 4350 PCB

Rogers 4350B PCB materials are proprietary woven glass reinforced hydrocarbon/ceramics with electrical performance close to PTFE/woven glass and the manufacturability of epoxy/ glass. Rogers 4350B laminates provide tight control on dielectric constant (Dk) and maintain low loss while utilizing the same processing method as standard epoxy/glass. Available at a fraction of the cost of conventional microwave laminates, rogers 4350B laminates do not require the special through-hole treatments or handling procedures as PTFE based materials. These materials are UL 94 V-0 rated for active devices and high power RF designs.

Features

• Dk of 3.48 +/- 0.05

• Dissipation factor of 0.0037 at 10 GHz

• Low Z-axis coefficient of thermal expansion at 32 ppm/°C

Benefits

• Processes like FR-4 at lower fabrication cost

• Competitively priced

• Excellent dimensional stability

1. High frequency PCB with small dielectric constant, loss will be very small, and advanced induction heating technology can achieve the needs of the target heating, very high efficiency. Of course, while paying attention to efficiency, it also has the characteristics of environmental protection, which is very suitable for the development direction of today's society. Rogers 4350 4 mil laminates have a process Dk of 3.33 ± 0.05 and are in conformance with IPC-4103A/240. All other Rogers 4350 laminate thicknesses are /11 and /240 compliant.Rogers 4350B LoPro® laminates do not share the same UL designation as standard Rogers 4350B laminates. A separate UL qualifi cation may be necessary. 

2. The transmission speed is inversely proportional to the square root of the dielectric constant, meaning that the smaller the dielectric constant, the faster the transmission speed. This is the advantage of high frequency PCB, it uses special material, not only to ensure the characteristics of small dielectric constant, but also to maintain the stability of the operation, for signal transmission is very important.

3. Widely used in various industries for precision metal material heat treatment requirements of high frequency PCB, in the field of the process, not only can realize the depth of different parts of heat, but also according to the characteristics of the local key heating, both the surface and deep, centralized or decentralized heating mode, and can be easily accomplished.

4 dielectric constant and medium, there will be certain requirements for the environment, especially in the south, wet weather will seriously affect the use of PCBs. High frequency PCBs made of extremely low water absorption materials can challenge such environments, but also have the advantages of chemical corrosion resistance, moisture resistance, high temperature resistance and great peel strength, so that high frequency PCBs play a powerful performance.

Advantages of Rogers 4350B PCB

• High-frequency Rogers 4350B PCB has high density and improved signal. It offers a frequency range from 500MHz to 2GHz, ideal for high-speed designs.

• The use of the ground layer further improves the signal quality and reduces the electromagnetic wave.

• Reduce circuit impedance and provide shielding effect

• By reducing the distance between the plane and the routing layer, crosstalk can be avoided
