  6. Photolithography: Photolithography involves exposing the photoresist layer to UV light through a photomask that contains the circuit pattern. The UV light cures the photoresist in areas where traces are desired, while other areas remain uncured.
  7. Etching:After exposure, the PCB panel undergoes etching to remove the unprotected copper areas not covered by cured photoresist. This process defines the fine traces and spaces between traces on the PCB. Etching is carefully controlled to achieve precise trace widths and spacing as per design specifications.
  8. Surface Finish: Once the desired circuit pattern is etched into the copper, the PCB undergoes surface finishing. Common finishes for microtrace substrates include Electroless Nickel Immersion Gold (ENIG) or immersion silver, which ensure good solderability and long-term reliability.
  9. Drilling and Via Formation: Holes are drilled into the substrate to create via connections between different layers of the PCB. For microtrace substrates, this often involves drilling very fine holes or using laser drilling techniques for microvias, which are small-diameter vias used in high-density interconnects.
  10. Final Inspection and Testing: The finished PCB panels undergo inspection to verify that all features and dimensions meet the design specifications. Electrical testing may include impedance testing to ensure that the PCB meets the required impedance values for high-frequency performance.
  11. Quality Control and Packaging: After passing inspection, the PCB panels are separated into individual boards (if they were panelized) and prepared for shipping or further assembly processes.

The microtrace substrate fabrication process requires precision at every step to achieve the fine features and high-quality performance needed for demanding applications in telecommunications, aerospace, medical devices, and other fields where signal integrity and reliability are critical. Advanced manufacturing technologies and strict adherence to design guidelines are essential to produce these specialized PCBs successfully.
