Overview of UGPCB FR408
UGPCB FR408 is mid loss, epoxy laminate and prepreg. It is a high-performance FR-4 epoxy laminate and prepreg system designed for advanced circuitry applications.
PCB Material TG of FR4
Typical TG Values
The PCB material TG (Glass Transition Temperature) of FR4 is usually 130 and 180 or higher.
Application Example: UGPCB 370HR
For example, the practical frequency of UGPCB 370HR can reach 10G. The application of UGPCB 370HR is mostly in high-frequency communication, microwave, high-speed digital circuits, and other fields.
Comparison Between UGPCB FR408 and UGPCB 370HR
Loss and Temperature Stability
But the loss of UGPCB 370HR is too large, and it is still similar to ordinary FR4. The biggest advantage of UGPCB 370HR is that its temperature stability will be better. The loss of UGPCB FR408 is only one-tenth of UGPCB 370HR.
Advantages of UGPCB FR408
This is another product besides UGPCB 370HR. UGPCB FR408’s low dielectric constant (Dk) and low dissipation factor (Df) make it an ideal candidate for broadband circuit designs requiring faster signal speeds or improved signal integrity.
Compatibility with FR-4 Processes
UGPCB FR408 is compatible with most FR-4 processes. This feature allows the use of UGPCB FR408 without adding complexity to current fabrication techniques.
