2 - Layer, 20mil TLY - 5 PCB: Stable and Low - Loss Solution for Automotive Radar and Millimeter - Wave Applications |
|
|
|
|
|
|
|
1. Introduction of TLY-5
TLY-5 laminates are produced using extremely lightweight woven fiberglass, offering superior dimensional stability compared to chopped fiber-reinforced PTFE composites. The woven structure of TLY-5 provides enhanced mechanical stability, making it an excellent choice for high-volume manufacturing. With its low dissipation factor, TLY-5 is well-suited for demanding applications such as 77 GHz automotive radar systems and other millimeter-wave frequency antennas.
