Comparison of high frequency circuit board Rogers RO4003C and RO4350B

Dissipation factor DF

The smaller the dissipation factor, the smaller the signal loss during transmission. Both RO4003C and RO4350B have extremely low dissipation factors, and the transmission line loss of RO4350B is larger than that of RO4003C during transmission.

Ɛr Thermal stability coefficient

The change of temperature will cause the change of the dielectric constant. Through the thermal stability coefficient of Ɛr of RO4003C and RO4350B, the dielectric constant of the two sheets at a certain temperature can be estimated. The lower the absolute value of the thermal stability coefficient of Ɛr, the more stable the dielectric constant is over the operating temperature range.

Thermal expansion coefficient

The thermal expansion coefficient of copper is about 19ppm/℃, and both RO4003C and RO4350B have a thermal expansion coefficient similar to that of copper. ppm/°C). RO4003C is closer to the thermal expansion coefficient of copper in the X/Y axis, and has better dimensional stability during sheet processing; R04350B is closer to the thermal expansion coefficient of copper in the Z axis, which can better protect the metallized vias.

Water absorption

The water absorption rate represents the ability of an object to absorb water under normal atmospheric pressure. The higher the water absorption rate, the higher the proportion of water in the medium, and the greater the impact on the characteristics of the medium. Working in a high humidity environment, it is more suitable to choose RO4003C sheet with low water absorption.

Beton PCB specializes in R&D and production of various high-end pcb boards, high-precision FPC circuit boards and PCB circuit boards, high-frequency, mixed-pressure PCB proofing and mass production.
