RF PCB Based On 62mil CER-10 Laminates With Black Soldermask And Immersion Tin

Introducing the high frequency PCB which built on CER-10 laminates. The CER-10 is an organic-ceramic laminate in the ORCER family of Taconic products, featuring a woven glass reinforcement. It combines Taconic's expertise in ceramic fill technology and coated PTFE fiberglass to deliver exceptional interlaminar bond strength and solder resistance. The proprietary composition of CER-10 ensures low moisture absorption and uniform electrical properties. With its woven glass reinforcement, CER-10 offers excellent dimensional stability and enhanced flexural strength, making it reliable even in extreme thermal environments.

The CER-10 material boasts impressive features. It has a Dk of 10 at 10GHz, ensuring reliable signal integrity in high-frequency applications. The dissipation factor is as low as .0035 at 10GHz, minimizing signal loss. The coefficient of thermal expansion (CTE) is carefully matched to copper, enabling plated-through-hole reliability in the face of extreme thermal environments. With a thermal conductivity of 0.63 W/mk, the CER-10 substrate efficiently dissipates heat, contributing to effective thermal management. Its moisture absorption is as low as 0.02%, enhancing dimensional stability and reducing the risk of warping or distortion. The dielectric breakdown of 44 kV ensures robust insulation capabilities.

The CER-10 laminate also offers several benefits. It exhibits exceptional interlaminar bond strength and solder resistance, guaranteeing the durability and reliability of the PCB. The low moisture absorption enhances dimensional stability, reducing the risk of warping or distortion during manufacturing and in various operating conditions. The low Z-axis expansion of CER-10 (CTE 46 ppm/°C) ensures reliable plated-through-hole connections, even in environments with rapid temperature changes. The stable DK over frequency allows for precise control of impedance and optimal signal propagation. Additionally, the CER-10 PCB enables circuit miniaturization due to its enhanced dimensional stability and increased flexural strength.
