Taconic TLY-5 and Rogers 5880 are two common high-performance laminated materials in the market, often used for high-frequency and microwave applications. Although they have similar technical specifications, there are still subtle differences in practical applications.
ROGERS high-frequency circuit board material RT/duroid 5880 and TACONIC high-frequency circuit board material TLY-5 both have a Dk of 2.20 and a Df of 0.0009. The key technical indicators of the two different high-frequency circuit board materials from different manufacturers appear to be the same, which makes it difficult for us to make a decision.
The following points can be used for comparison
From an electrical performance perspective, both Taconic TLY-5 and Rogers 5880 have low dielectric constants (Dk=2.2) and loss factors (Df=0.0009), making them highly suitable for applications up to millimeter wave frequencies.
Depending on the specific frequency and application, there may be slight differences in the response of these two materials. For example, TLY-5 performs better in high humidity environments and applications that require precise size control due to its extremely low water absorption rate and superior structural stability.
Considering physical properties and processing conditions, TLY-5 is made of textured glass fiber, providing higher mechanical stability and suitable for large-scale production. Rogers 5880 is known for its excellent copper foil adhesion and processing flexibility.
The inventory status and delivery cycle of PCB suppliers are also factors that designers need to consider when choosing Taconic TLY-5 or Rogers 5880. According to user feedback, Taconic's materials may require longer ordering cycles, while Rogers can provide faster responses.
From the perspective of application scope, both Taconic TLY-5 and Rogers 5880 have a wide range of applicability, from aerospace to automotive radar systems, to communication equipment. However, depending on specific design requirements and the intended use of the final product, one material may be more suitable for a particular application scenario than another.
Comparing at the same frequency: When comparing different high-frequency circuit board materials, dielectric constant Dk and loss factor Df are the most common reference indicators. These two technical indicators are frequency dependent parameters, with dielectric constant Dk typically decreasing and loss factor Df typically increasing with frequency
Comparing under the same testing method: Not every high-frequency circuit board material is tested using the same method or under the same conditions, and differences in testing methods can also lead to differences in key parameters of the material, such as Dk and Df
Comparing in the same direction: Most high-frequency circuit board materials are anisotropic, which means that the same parameter has different values when measured in different directions. Taking Dk as an example, most high-frequency circuit board materials have different Dk values in the x-y plane and z-axis (thickness)
Comparing at the same temperature: For most commercial high-frequency circuit board materials, Dk is closely related to temperature. Although most high-frequency circuit board materials measure Dk at room temperature (around+23 º C~+25 º C), even for the same high-frequency circuit board material, a deviation of a few degrees above room temperature can cause the measured Dk value to be different from the measured value at room temperature
Taconic TLY-5 and Rogers 5880
Comparing the Taconic TLY-5 with the Rogres 5880 high-frequency board, it may not be easy to compare high-frequency circuit boards from different suppliers. When comparing data manuals for high-frequency board materials, a good starting point is to ensure that the parameters being compared are the same - using the same testing method to measure basic high-frequency board material parameters such as Dk and Df at the same testing frequency and temperature. Only by using the same testing method to measure these parameters can we objectively and accurately compare different high-frequency board materials and effectively estimate the performance of the final selected high-frequency board material!
Although Taconic TLY-5 and Rogers 5880 share similar characteristics in multiple aspects, they still demonstrate their unique advantages in practical applications. The choice of material depends on specific design requirements, budget constraints, and supply chain considerations.
