Features and Benefits

The TLX-0 PCB 10mil comes equipped with a host of impressive features that enhance its performance and reliability. With a DK of 2.45 +/- 0.04 at 10GHz and a dissipation factor (DF) of 0.0021 at the same frequency, TLX-0 ensures low signal loss and excellent signal integrity. Additionally, its low moisture absorption of 0.02% safeguards against environmental moisture effects.

The dimensional stability of TLX-0 is a key benefit, as it enables precise manufacturing and consistent performance over time. With X, Y, and Z coefficient of thermal expansion (CTE) values of 21 ppm/°C, 23 ppm/°C, and 215 ppm/°C respectively, TLX-0 remains stable even in challenging temperature environments. Its peel strength of 12 lbs/in showcases its robust mechanical properties, ensuring reliable bonding and durability.

PCB Construction and Specifications

The TLX-0 PCB 10mil substrate is a 2-layer rigid PCB constructed with meticulous attention to detail. With a copper layer thickness of 35 μm on both sides and a TLX-0 core thickness of 0.254 mm (10mil), this PCB strikes the perfect balance between performance and compactness.

The board dimensions of 80mm x 40.8 mm, with a tolerance of +/- 0.15mm, provide ample space for diverse RF designs. The minimum trace/space of 6/7 mils and a minimum hole size of 0.3mm further contribute to the PCB's flexibility and adaptability. The finished board thickness of 0.32mm, coupled with a 1oz (1.4 mils) outer layer copper weight, ensures a compact yet robust structure.

To enhance reliability, the Taconic TLX-0 PCB features 20 μm via plating thickness and an immersion gold surface finish. While it does not include top or bottom silkscreen or solder mask, the absence of these elements allows for precise and efficient manufacturing without compromising performance. Each PCB undergoes a rigorous 100% electrical test before shipment, ensuring optimal functionality.
