TACONIC RF-35 is an organic ceramic laminate material.
It is a reinforced glass material based on glass fiber cloth, which combines ceramic filling technology with glass fiber coated teflon PCB technology.
Applications
RF-35 is ideal for low-cost, high-volume commercial microwave and wireless frequency applications.
Copper Foil Boards
RF-35 1/20Z and 10Z copper foil boards have excellent peel strength even with standard epoxy materials.
These boards can be reworked at any time.
Propriétés thermiques
The glass transition temperature of RF-35 is over 315°C.
RF-35’s ultra-low water absorption and low loss factor minimize phase shift in the frequency range.
Dimensional Stability
The use of glass fiber cloth in RF-35’s design and development ensures dimensional stability.
Laminate Materials
RF-35 laminate materials generally come with single-sided or double-sided 1/20Z, 10Z, and 20Z thick electrolyte copper foil.
Different sizes of PCB can be selected according to requirements.
RF-35 Microwave Material Properties
Thermal Expansion and Temperature
For RF-35 microwave material, the relationship between the thermal expansion rate in the Z-axis direction and temperature is significant.
Dielectric Constant and Temperature
RF-35’s dielectric constant changes with temperature.
Dielectric Loss and Temperature
RF-35’s dielectric loss varies with temperature.
Dielectric Constant and Frequency
The relationship between the dielectric constant and frequency of RF-35 microwave materials is important.
Taconic’s High-Frequency PCB Board Materials
Aperçu
Taconic’s high-frequency PCB board materials are based on polytetrafluoroethylene (PTFE), commonly known as Teflon.
Teflon is a resin with very low loss and a dielectric constant of about 2.0.
It is also a very good insulating material with properties such as being non-absorbent, wear-resistant, resistant to high and low temperatures, and corrosion-resistant.
Dielectric Constant and Tangent Loss
The dielectric constant (Ne sait pas) of Taconic’s Teflon high-frequency PCB sheets ranges from 2.17 à 10.
The frequency covers the range from 2GHz to 110GHz.
Tangent loss (Df) is less than 0.0025 at 2GHz.
The stability of Dk is excellent, with minimal changes with frequency and temperature.
Applications of Taconic’s Materials
Taconic provides PTFE/woven glass fiber woven sheets for microwave, radiofréquence (RF), and high-speed digital signal processing markets.
These sheets are used in various applications such as LNAs, LNBs, PCS/PCN antenna systems, GPS and UMTS antenna systems, amplificateurs de puissance, composants passifs, collision avoidance radar systems, aviation-assisted remote control technology, and phased array radar systems.
Taconic’s History and Competitiveness
Taconic has a history of 40 years and has produced high-frequency PCB materials for nearly 20 années.
It is the largest supplier of high-frequency PCB materials.
Headquartered in the United States, with the Asia-Pacific headquarters in South Korea.
Teflon sheets can be used for both high-frequency and high-speed applications.
