3-Layer PCB with Rogers RO4003C/RO4450F, 1.82mm Thickness, Black Solder Mask, and Immersion Gold Finish

(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)

Hi, I’m excited to share details about one of our premium products: the 3-layer PCB with Rogers RO4003C and RO4450F materials. This PCB is designed for performance-sensitive RF and microwave applications, offering high thermal stability, low signal loss, and excellent dimensional stability. With a 1.82mm thickness, black solder mask, and white silkscreen, this PCB is perfect for cellular base stations, automotive radar, and broadcast satellites.

1. Overview of the 3-Layer PCB

This 3-layer rigid PCB uses a combination of Rogers RO4003C for the core and RO4450F bonding ply, offering the high-frequency performance of PTFE materials with the easy manufacturability of FR-4. The board has been designed with blind vias connecting the top layer to the inner layer to ensure efficient interconnectivity without sacrificing signal integrity.

The black solder mask on the top layer enhances its durability, while the immersion gold surface finish ensures excellent solderability and corrosion resistance. The white silkscreen provides clarity for component placement, making assembly easier and more accurate. Every PCB undergoes 100% electrical testing and is manufactured to IPC-Class-2 standards, ensuring high quality and reliability.
