We are thrilled to introduce our latest delivery of the AD350A PCB, a cutting-edge solution that brings unparalleled performance to your high-power connectivity needs.

Introduction to AD350A:
The Rogers AD350A PCB substrate is a specialty material designed for high-power designs, offering high thermal conductivity and low coefficient of thermal expansion (CTE). With its woven fiberglass reinforced, ceramic-filled, PTFE-based composite construction, AD350A provides exceptional performance in applications where temperature extremes and heat rejection are critical factors.

Key Features:
Precisely controlled dielectric constant of 3.5 ± 0.05 at 10 GHz/23°C ensures reliable signal transmission.
Low loss tangent of 0.003 at 10 GHz, 23°C @ 50% RH, enabling efficient and high-performance circuitry.
Low Z-axis thermal expansion of 35 ppm/°C, ensuring dimensional stability under varying temperatures.
Decomposition Temperature (Td) exceeding 500°C, providing excellent thermal stability and reliability.
Moisture absorption rate of 0.1%, safeguarding against environmental factors and maintaining performance integrity.
Coefficient of Thermal Expansion (CTE) in X-axis of 18 ppm/°C, Y-axis of 18 ppm/°C, and Z-axis of 63 ppm/°C, providing stability in different temperature conditions.
Low PIM of -159dBC at 30 mils and -163dBC at 60 mils, ensuring superior antenna performance and reduced interference.
Good thermal conductivity of 0.44 W/m-K, facilitating effective heat dissipation.

Benefits:
Superior plated through-hole (PTH) adhesion, ensuring reliable connections.
Excellent heat dissipation and management, enabling reliable operation in high-power applications.
High consistency performance, ensuring reliable signal transmission and reception.
