The PCB material features a Dielectric Constant of 3.5 at 1.9GHz, ensuring efficient signal transmission and minimal signal loss. With a low Dissipation Factor of 0.0018 at 1.9GHz, this PCB exhibits excellent electrical characteristics, contributing to optimal circuit performance. It also boasts a remarkable Dielectric Breakdown strength of 41 kV, ensuring durability and protection against electrical breakdowns.

The Taconic ORCER material demonstrates a low coefficient of thermal expansion (CTE) of 19 ppm/°C and 24 ppm/°C in the x-y direction, and 64 ppm/°C in the z direction. This dimensional stability helps maintain the integrity of the PCB under varying temperatures and ensures reliable performance over time.

Benefiting from its low-cost advantage, this PCB offers exceptional peel strength, further enhancing its durability and resistance to delamination. The exceptionally low Dissipation Factor contributes to efficient signal transmission without significant energy loss. Additionally, its low moisture absorption and enhanced surface smoothness add to its overall reliability and performance.

The stackup of this PCB consists of two copper layers, each with a thickness of 35 μm, sandwiching the RF-35 core with a thickness of 20mil (0.508 mm). This construction ensures optimal signal integrity and structural integrity.

With a board dimension of 115mm x 59 mm (+/- 0.15mm), this PCB provides ample space for your circuit design while maintaining precise fitment. The minimum trace/space of 6/4 mils allows for intricate circuit routing, and the minimum hole size of 0.3mm facilitates efficient component integration. The finished board thickness of 0.6mm and 1oz (1.4 mils) outer layer copper weight strike a balance between flexibility and durability.

For surface finish, the Immersion Tin coating ensures excellent solderability and corrosion resistance. The top silkscreen is presented in white, providing clear component identification. The absence of bottom silkscreen and solder mask allows for flexibility in customization.

Prior to shipment, each PCB undergoes a rigorous 100% electrical test, ensuring its functionality and adherence to IPC-Class-2 quality standards.

The Gerber RS-274-X artwork format is supplied, enabling seamless integration into your manufacturing process.
