Radar systems have extremely high requirements for the heat resistance, stability and signal integrity of PCBs. High Tg PCB (High Glass Transition Temperature PCB) is its core supporting component, which can adapt to different frequency bands and working conditions, solve the failure problems caused by high temperature, high frequency and high vibration, and ensure the stable operation of the system.
Core Product Advantages
Combined with the strict working requirements of radar systems, the core advantages of this product focus on key dimensions such as heat resistance, stability and signal, accurately matching the operational needs of the equipment.
- Ultra-high heat resistance: Tg value ≥ 170℃ (up to 200℃+ for high-end models), capable of withstanding the peak temperature of 260℃+ for lead-free soldering, avoiding substrate softening and delamination.
- Dimensional stability: Z-axis CTE ≤ 65ppm/℃, high matching degree with copper foil, reducing warpage and cracking, and ensuring signal transmission accuracy.
- Excellent signal performance: Dielectric loss ≤ 0.008, reducing high-frequency signal attenuation, suitable for 77GHz millimeter-wave radar.
