5. Etching: Use photolithography and chemical etching techniques to remove excess copper from the substrate, leaving behind the desired circuit patterns and traces. Etching is performed using specialized etchants that selectively dissolve the copper while protecting the circuit features with photoresist.
6. Drilling: Drill holes, known as vias, through the PCB substrate to facilitate interconnection between different layers. High-precision drilling equipment is used to create vias with precise dimensions and locations.
7. Through-Hole Plating: Plate the vias with conductive material, typically copper, to establish electrical connections between different layers of the PCB. This process, known as through-hole plating, ensures reliable conductivity and signal integrity throughout the PCB.
8. Surface Finishing: Apply a surface finish to protect the copper traces from oxidation and improve solderability. Common surface finishes for microwave PCBs include immersion gold, ENIG (Electroless Nickel Immersion Gold), or immersion silver.
9. Solder Mask Application: Apply a solder mask layer over the PCB surface to insulate the copper traces and prevent solder bridging during assembly. Solder mask also provides protection against environmental factors and facilitates component placement.
10. Silkscreen Printing: Optionally, add component designators, logos, and other identifying information to the PCB using silkscreen printing. This step helps with component placement and assembly.
11. Final Inspection: Conduct visual inspection, electrical testing, and dimensional verification to ensure the PCBs meet the required specifications and quality standards.
12. Panelization and Routing: If producing multiple PCBs, the panels are routed to separate individual PCBs. Careful attention is paid to maintaining the integrity of the circuits during this process.

Once completed, the fabricated microwave PCBs are ready for assembly with electronic components to form complete satellite communication systems or other microwave applications.
