7. Etching: Perform chemical etching to remove unwanted copper, leaving only the desired circuit traces. This step must be precise to ensure integrity in high-frequency applications.
8. Surface Finishing: Apply surface finishes such as ENIG (Ouro de imersão em níquel eletrolítico) or OSP (Organic Solderability Preservative) to enhance solderability and protect copper traces from oxidation.
9. Testing and Inspection: Conduct electrical testing and visual inspections to identify any defects or irregularities. This step may involve automated optical inspection (AOI) or electrical continuity testing.
10. Assembléia: Once tested, the PCBs can be assembled with components through techniques such as surface mount technology (SMT) or through-hole soldering, depending on design specifications.
11. Final Testing: Perform additional testing on the fully assembled PCB to ensure it meets all operational and performance specifications, particularly for high-frequency behavior.

This fabrication process ensures that HF Radar PCBs are produced with high accuracy and reliability, essential for their performance in radar applications.
