What is the Microwave/Microtrace PCB Fabrication Process?

The fabrication process for Microwave or Microstrip PCBs involves several steps to ensure precise manufacturing and optimal performance at high frequencies. Here’s an overview of the typical fabrication process:

  1. Substrate Preparation:The process starts with selecting a high-quality substrate material such as Rogers, Teflon (PTFE), or FR-4. The substrate is typically in the form of a laminate sheet with copper cladding on one or both sides. The substrate sheets are cleaned and inspected for defects before proceeding to the next step.
  2. Copper Cladding: The substrate sheets are coated with a thin layer of copper on one or both sides through processes like lamination or electroplating. The thickness of the copper layer is carefully controlled to meet the design specifications for trace width and impedance.
  3. Photoresist Application: A layer of photoresist is applied to the copper-clad substrate using techniques such as roller coating or spray coating. The photoresist acts as a mask for the subsequent etching process.
  4. Exposure and Development:The photoresist is exposed to ultraviolet (UV) light through a photomask containing the desired circuit pattern. The exposed photoresist is then developed to remove the unexposed areas, leaving behind the pattern of traces and pads on the substrate.
  5. Etching:The substrate is immersed in an etchant solution, such as ferric chloride or ammonium persulfate, which selectively removes the exposed copper, leaving the desired traces and pads on the substrate.
  6. Strip and Clean:The remaining photoresist is stripped from the substrate using solvents or alkaline solutions. The substrate is then thoroughly cleaned to remove any residues and contaminants.
  7. Drilling:Holes are drilled through the substrate at locations specified by the design for through-hole components or via connections between layers. High-precision drilling equipment is used to ensure accurate hole placement.
  8. Through-hole Plating:If the PCB design includes through-hole vias, the holes are plated with conductive material to establish electrical connections between the different layers of the PCB. This process typically involves electroplating copper or other metals into the holes.
  9. Surface Finish:The exposed copper surfaces are treated with a surface finish to protect them from oxidation and facilitate soldering during assembly. Common surface finishes include HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), and OSP (Organic Solderability Preservative).
  10. Final Inspection: The fabricated PCBs undergo thorough inspection to verify dimensional accuracy, trace integrity, and absence of defects. Automated optical inspection (AOI) and electrical testing may be performed to ensure compliance with specifications.
  11. Routing and Panelization: After inspection, the individual PCBs are routed from the larger panel if necessary, and any remaining rough edges are smoothed. The PCBs are then separated or panelized according to customer requirements.
  12. Packaging and Shipping:The finished PCBs are packaged securely to protect them during transportation and storage before they are shipped to the customer or assembly facility.

By following these steps with precision and attention to detail, manufacturers can produce high-quality Microwave or Microstrip PCBs that meet the stringent requirements of high-frequency applications.
