A Cross blind/buried vias PCB is a high-density, high-performance printed circuit board (PCB) design solution commonly used in complex electronic devices. This design employs blind and buried via technologies to maximize connections between different layers of the PCB while minimizing space occupation. Blind vias refer to holes visible only on one side, while buried vias are holes completely embedded within the PCB. By employing cross-layer routing, blind and buried vias can traverse between different layers, enabling more intricate circuit connections and enhancing the PCB’s performance and reliability. This design not only reduces the size of the PCB but also lowers signal transmission delay and improves signal integrity. Consequently, Cross blind/buried vias PCB has become the preferred design solution for many high-end electronic products such as smartphones, tablets, and high-performance computers.

Here’s an overview of the Rogers Cavity PCB fabrication process:

  1. Design: The process begins with the PCB design phase, where the circuit schematic and layout are created using PCB design software. Design considerations should include material selection, layer stackup design, cavity placement and dimensions, transmission line routing, grounding, and thermal management.
  2. Material Selection: Choose the appropriate Rogers high-frequency laminate material based on the required electrical properties for the specific application.
  3. Preparation: Prepare the substrate materials by cutting them to the required size according to the PCB design specifications.
  4. Layer Stackup: Assemble the layers according to the designed stackup, including the placement of cavity structures if applicable. Bond the layers together using heat and pressure to form a solid substrate.
  5. Drilling: Drill holes for component mounting pads, vias, and interconnections using precision drilling equipment. Special attention should be paid to the accuracy of hole placement and size to ensure proper alignment and impedance control.
  6. Copper Plating: Apply a thin layer of copper to the substrate surface using processes such as electroless copper plating or electroplating. This copper layer serves as the conductive trace pattern for the circuit.
  7. Circuit Patterning: Apply a layer of photoresist material to the copper surface and expose it to UV light through a photomask with the desired circuit pattern. Develop and etch away the unexposed photoresist to remove unwanted copper, leaving behind the desired circuit traces.
  8. Cavity Creation (if applicable): Mill or rout out the cavity structures within the substrate layers using CNC machining equipment. Ensure precise dimensions and alignment to maintain structural integrity and electrical performance.
  9. Surface Finish: Apply a surface finish to protect the exposed copper traces from oxidation and facilitate solderability. Common surface finishes include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservative).
  10. Component Assembly: Mount and solder electronic components onto the PCB using surface mount technology (SMT) or through-hole technology (THT), depending on the design requirements.
  11. Testing and Inspection: Perform electrical testing and visual inspection to verify the functionality and quality of the assembled PCBs. This may include continuity testing, impedance measurements, and visual inspection for defects.
  12. Final Finishing: Trim excess material from the PCB edges, apply labeling or marking as needed, and package the finished PCBs for shipping or further assembly.

Throughout the fabrication process, strict quality control measures should be implemented to ensure the integrity and reliability of the Rogers Cavity PCBs, especially in high-frequency applications where signal integrity is critical.
