Detail Information

Product Description

Rogers TC350 laminates are printed circuit board substrates that comprise PTFE, highly thermally conductive ceramic fillers, and woven glass reinforcement. They offer designers a unique combination of low insertion loss and higher thermal conductivity, enabling superior reliability and reduced operating temperatures in high-power applications.

Exceptional dielectric constant stability across various temperatures is maintained by TC350 laminates, a crucial feature for power amplifier and antenna designers in maximizing gain and minimizing bandwidth loss. This stability is also key for phase and impedance-sensitive devices like network transformers in power amplifiers or Wilkinson Power Dividers.

Key Features

• The dielectric constant (Dk) remains stable at 3.5 at 1MHz, 1.8GHz, and 10GHz.
• A low dissipation factor of .0015 at 1MHz, 0.0018 at 1.8GHz, and 0.002 at 10GHz ensures minimal signal loss and excellent signal integrity.
• The thermal conductivity is high at 0.72 W/mk, facilitating efficient heat dissipation and management.
• The thermal coefficient of Dk is low at -9 ppm/°C, ensuring stable electrical performance across a temperature range of -40°C to 140°C.
• Moisture absorption is limited to 0.05%, providing excellent dimensional stability.
• Mechanical stability is achieved with a CTE x-axis of 7 ppm/°C, CTE y-axis of 7 ppm/°C, and CTE z-axis of 23 ppm/°C over a temperature range of 50°C to 150°C.

Reliability and Manufacturing Details

• The recommended PCB stackup for a 2-layer rigid PCB using TC350 laminates consists of a copper layer on each side (35 μm) with a TC350 core thickness of 0.508 mm (20mil).
• PCB construction details include board dimensions of 68.35mm x 41.4mm with a thickness of 0.6mm. The PCB features a minimum trace/space of 6/5 mils, a minimum hole size of 0.5mm, and no blind vias. The surface finish is Hot Air Solder Level (HASL), with top and bottom solder masks in green.
• The manufactured PCBs adhere to IPC-Class-2 quality standards, ensuring reliable performance and construction.
