High Frequency Rigid PCB Circuit Board


1mm High Frequency PCB


8 Layer High Frequency PCB

Introducing our high-frequency PCB built on the robust 370HR substrate. Designed for applications that demand exceptional performance in the realm of high frequencies, this PCB surpasses expectations in thermal stability, reliability, and compatibility with advanced manufacturing processes. With its cutting-edge features and superior construction, it is the ideal choice for industries requiring reliable high-frequency solutions, such as telecommunications, aerospace, and radar systems.


The 370HR substrate, renowned for its high-performance characteristics, utilizes a patented 180°C Tg FR-4 multifunctional epoxy resin system. This innovative design ensures optimal thermal performance and reliability, meeting the stringent requirements of high-frequency applications. The 370HR laminate and prepregs incorporate high-quality E-glass glass fabric, guaranteeing superior resistance to Conductive Anodic Filament (CAF) formation, a leading concern in high-frequency circuitry. Additionally, the 370HR PCB surpasses traditional FR-4 materials with its exceptional mechanical, chemical, and moisture resistance properties.


Key Features:
- UL Certified and RoHS compliant, demonstrating adherence to stringent quality and environmental standards.
- CAF resistant, safeguarding against conductive filament formation and ensuring long-lasting performance.
- Glass Transition Temperature (Tg) of 180°C, providing exceptional thermal stability under high-frequency conditions.
- Decomposition Temperature (Td) of 340°C, ensuring durability and resistance to elevated temperatures.
- Time to Delaminate by TMA (Copper removed): T260 of 60 minutes, T288 of 30 minutes, indicating excellent thermal performance.
