  3. Layer Stacking and Lamination:If multiple layers are required (typical in multilayer PCBs), individual substrate layers are stacked according to the design specifications. The layers are then laminated together under controlled temperature and pressure conditions. Lamination ensures proper bonding between layers and forms a solid structure.
  4. Drilling: After lamination, precision drilling is performed to create holes for vias and component leads. The drilling process must maintain tight tolerances to ensure accurate alignment of vias and proper clearance for component mounting.
  5. Copper Plating: Copper foil is bonded to the substrate surfaces through an electroplating process. This step involves applying a thin layer of copper to the substrate to form conductive traces and pads. The thickness and quality of the copper plating are critical to achieving desired electrical performance.
  6. Circuit Patterning: Using photolithography or direct imaging techniques, a pattern of conductive traces and pads is defined on the copper-clad substrate. This step involves applying a photoresist layer, exposing it to UV light through a photomask, and developing it to selectively remove the photoresist and expose the copper for etching.
  7. Etching: Copper that is not protected by the developed photoresist is etched away using an etchant solution, leaving behind the desired circuit pattern on the substrate. Careful control of the etching process ensures that trace widths and spacing meet design specifications for controlled impedance.
  8. Surface Finish: Once the circuit pattern is defined, a surface finish is applied to the exposed copper to protect it from oxidation and facilitate soldering during assembly. Common surface finishes include immersion gold, immersion silver, and HASL (Hot Air Solder Leveling).
  9. Final Inspection and Testing: After fabrication, the substrates undergo rigorous inspection and testing to verify dimensional accuracy, electrical continuity, and adherence to design specifications. Testing may include electrical tests such as impedance measurements and insulation resistance tests.
  10. Quality Assurance: Throughout the fabrication process, stringent quality control measures are implemented to ensure consistency and reliability of the RF High Frequency Package Substrates. This includes monitoring process parameters, material characteristics, and final product performance.
