  4. Lamination: Layer the substrate material and prepregs (pre-impregnated resin) according to the specified layer stack-up. Apply heat and pressure in a laminating press to bond the layers together. This step ensures proper alignment and bonding of the inner layers.
  5. Drilling: Precision drill the PCB to create holes for vias and component mounting pads. Use CNC (Computer Numerical Control) drilling machines with high accuracy to achieve the desired hole sizes and positions.
  6. Electroless Copper Deposition: Coat the inner layers with a thin layer of electroless copper to facilitate subsequent plating processes. This step prepares the surface for creating conductive traces.
  7. Plating: Electroplate the drilled holes and exposed copper surfaces with additional copper to build up the thickness of the conductive traces and vias. This process ensures electrical conductivity and durability.
  8. Etching: Apply a photoresist mask to define the trace patterns on the outer layers. Use chemical etching to remove unwanted copper, leaving behind the desired trace patterns. The etching process must be precise to maintain trace widths and spacing.
  9. Surface Finish:Apply a surface finish to protect exposed copper traces from oxidation and ensure solderability. Common surface finishes include ENIG (Electroless Nickel Immersion Gold), HASL (Hot Air Solder Leveling), and OSP (Organic Solderability Preservatives).
  10. Silkscreen and Legend Printing: Optionally, apply silkscreen printing for component labels and legends on the PCB surface. This step helps in identifying components and their placements during assembly.
  11. Testing and Inspection: Perform electrical testing (such as continuity testing and impedance testing) and visual inspection to verify the integrity of traces, vias, and overall PCB quality. Testing ensures that the fabricated PCB meets design specifications.
  12. Final Fabrication Steps: Rout the PCB to its final shape and size. Cut individual PCBs from larger panels using CNC routing or V-cut methods. Clean the PCB thoroughly to remove any residues from the fabrication process.
