Description
Rogers 4003C vs 4350B PCB
Both Rogers 4003C and 4350B are high-frequency PCB laminates of Rogers Corporation. They have some different characteristics as follows:
Dielectric constant (Dk): The dielectric constant of Rogers 4003C is 3.38 ± 0.05; the dielectric constant of Rogers 4350B is 3.48 ± 0.05. The dielectric constant affects the performance of the circuit, such as impedance matching and signal transmission speed.
Loss factor (Df): The loss factor of 4003C at 10 GHz is 0.0027; the loss factor of 4350B at 10 GHz is 0.0037. A lower loss factor means less energy loss during signal transmission.
Flame retardancy: The 4003C material itself is bromine-free and does not have the UL 94 V-0 flame retardant grade; while 4350B has passed the UL 94 V-0 certification and may have an advantage in some applications with higher requirements for fire resistance.
Processing technology: Both are similar to the standard epoxy resin/glass cloth processing technology and do not require special pretreatment processes. However, compared to traditional microwave material laminates, they are more price competitive.
Overall, Rogers 4003C is suitable for performance-sensitive and high-volume applications and has a certain price competitiveness; while 4350B has better flame retardancy while maintaining similar performance. In practical applications, the choice of which laminate to use needs to be comprehensively considered based on specific design requirements, operating frequencies, cost limitations, and requirements for characteristics such as flame retardancy.
For more detailed information, it is recommended to refer to the official materials of Rogers Corporation or consult relevant technicians. At the same time, when purchasing, it is necessary to choose a regular supplier to ensure product quality. If you have other questions about PCB laminates, please feel free to continue asking.
It should be noted that PCBs produced by different manufacturers may have differences in certain parameters. In practical applications, other factors such as the number of layers of the PCB, PCB line width and spacing, PCB drilling aperture and other processing capabilities, as well as specific product requirements and usage environments, also need to be considered. If you need more accurate and detailed technical specifications, it is recommended to refer to the product manual of the relevant manufacturer or directly contact the PCB manufacturer for consultation.
