20 mil TSM-DS3 PCB Double-layer Immersion Silver Finish

Introducing the TSM-DS3 PCB, a cutting-edge printed circuit board engineered from a ceramic-filled reinforced material that sets a new standard in the industry. With very low fiberglass content (approximately 5%), TSM-DS3 rivals traditional epoxies in fabricating large-format complex multilayer designs. This innovative PCB is specifically developed for high-power applications, ensuring thermal stability and low loss for optimal performance in demanding environments.

Key Features

The TSM-DS3 PCB boasts a dielectric constant of 3.0 with a tight tolerance of ± 0.05 at 10 GHz/23°C, making it ideal for high-frequency applications. The dissipation factor is impressively low at 0.0014 at 10 GHz, contributing to minimal signal loss and enhanced reliability. With a high thermal conductivity of 0.65 W/m*K (unclad), this material efficiently dissipates heat away from critical components, ensuring that your designs remain stable even under high power conditions.

This PCB features low moisture absorption at just 0.07%, along with a coefficient of thermal expansion (CTE) that is matched to copper: 10 ppm/°C in the X-axis, 16 ppm/°C in the Y-axis, and 23 ppm/°C in the Z-axis. This ensures dimensional stability and reliability in thermal cycling environments.

Benefits

The TSM-DS3 PCB offers numerous advantages for engineers and designers:

- Low Fiberglass Content: With only ~5% fiberglass, the PCB maintains high performance while minimizing potential weaknesses associated with traditional materials.

- Dimensional Stability: The material's stability rivals that of conventional epoxy, enabling the fabrication of large-format, high-layer count PCBs.

- Consistency and Predictability: TSM-DS3 allows for complex PCBs to be built with high yield, ensuring reliability in production.

- Temperature Stability: The dielectric constant remains stable (± 0.25%) across a wide temperature range of -30°C to 120°C, making it suitable for various applications.

- Compatibility: The material is compatible with resistive foils, enhancing its versatility in design.

PCB Specifications

The stackup for this rigid PCB consists of:
