The fabrication process for multilayer R&D PCBs involves several steps, from design transfer to final inspection. Here’s an overview of the typical fabrication process:

  1. Design Transfer:The PCB design, usually created using software like Altium Designer or Eagle, is transferred to the fabrication house. This involves generating Gerber files, NC drill files, and fabrication drawings that contain all the necessary information for manufacturing.
  2. Material Selection:The fabrication house selects the appropriate materials for the PCB based on the design specifications, including the substrate material (typically FR-4 epoxy fiberglass), copper foil thickness, and prepreg (resin) thickness for the core and inner layers.
  3. Layer Preparation: The copper-clad laminate sheets are cleaned and prepared for the inner layer process. The layers are inspected for defects, and any necessary adjustments are made to ensure uniformity.
  4. Inner Layer Processing: The inner layers are coated with a photoresist material, onto which the circuit pattern is transferred using photolithography. After exposure to UV light through a mask, the unexposed areas are removed, leaving behind the circuit traces. The layers are then etched to remove excess copper.
  5. Layer Alignment and Lamination: Once the inner layers are processed, they are aligned and stacked together with prepreg layers to create the multilayer stack. The stack is then pressed under heat and pressure to bond the layers together, forming a solid panel.
  6. Drilling: Precision drills are used to create holes (vias) that connect the traces between different layers. These vias are plated with copper to ensure electrical conductivity.
  7. Plating: A thin layer of copper is electroplated onto the surface of the panel to reinforce the circuit traces and provide a solderable surface.
  8. Outer Layer Processing: The outer layers are coated with photoresist and patterned using the same photolithography process as the inner layers. After etching, a protective solder mask is applied to the surface to protect the copper traces and facilitate soldering.
  9. Surface Finish: The PCB surface is treated with a surface finish to protect against oxidation and improve solderability. Common surface finishes include HASL (hot air solder leveling), ENIG (electroless nickel immersion gold), and OSP (organic solderability preservative).
  10. Silkscreen Printing: Finally, component designators, logos, and other markings are printed onto the PCB surface using a silkscreening process for identification and assembly guidance.
  11. Testing and Inspection: The fabricated PCBs undergo electrical testing to ensure that all connections are intact and that there are no short circuits or open circuits. Visual inspection is also performed to check for any defects or irregularities in the PCB surface.
  12. Panelization and Separation: If multiple PCBs are fabricated on a single panel, they are separated into individual boards using routing or V-scoring techniques.
  13. Final Inspection and Packaging: The finished PCBs are inspected one last time to ensure quality and adherence to specifications. They are then packaged and shipped to the customer or assembly house for component placement and soldering.

By following these steps, the fabrication house can produce high-quality multilayer R&D PCBs that meet the design requirements and specifications provided by the customer.

How do you manufacture a Multilayer R&D PCB?

Manufacturing a multilayer R&D PCB involves several steps, from designing the circuit to assembling the components. Here’s a detailed overview of the process:

Traces are routed between components to establish electrical connections, considering factors such as signal integrity, power distribution, and thermal management.
  3. Layer Stackup Design: For multilayer PCBs, the layer stackup is designed to accommodate the required number of signal layers, power planes, and ground planes. The stackup determines the arrangement of copper layers and insulating materials, optimizing signal integrity and electromagnetic compatibility.
  4. Gerber File Generation: After completing the PCB layout, Gerber files, NC drill files, and other manufacturing documentation are generated. These files contain the necessary information for fabricating the PCB, including copper traces, hole locations, solder mask layers, and silkscreen markings.
  5. Fabrication Preparation: The Gerber files and other manufacturing documents are sent to a PCB fabrication house for production. The fabrication house reviews the files and prepares the manufacturing process, including selecting appropriate materials and equipment.
  6. Inner Layer Processing: The fabrication process begins with preparing the inner layers of the PCB. Copper-clad laminate sheets are cleaned and coated with a photosensitive film. The circuit pattern is transferred onto the film using photolithography and etched to remove excess copper, leaving behind the traces.
  7. Layer Alignment and Lamination: After processing the inner layers, they are aligned and stacked together with prepreg layers to form the multilayer stack. The stack is then pressed under heat and pressure to bond the layers together, creating a solid panel.
  8. Drilling and Plating: Precision drills are used to create holes (vias) that connect the traces between different layers. These vias are plated with copper to ensure electrical continuity. Through-holes and component mounting holes are also drilled at this stage.
  9. Outer Layer Processing: The outer layers of the PCB are processed similarly to the inner layers, with copper traces patterned using photolithography and etched to remove excess copper. A solder mask is applied to protect the copper traces and facilitate soldering, and silkscreen printing is used to add component designators and other markings.
  10. Surface Finish: The PCB surface is treated with a surface finish to protect against oxidation and improve solderability. Common surface finishes include HASL (hot air solder leveling), ENIG (electroless nickel immersion gold), and OSP (organic solderability preservative).
  11. Testing and Inspection: The fabricated PCB undergoes electrical testing to ensure all connections are intact and that there are no short circuits or open circuits. Visual inspection is also performed to check for defects or irregularities.
  12. Panelization and Separation: If multiple PCBs are fabricated on a single panel, they are separated into individual boards using routing or V-scoring techniques.
  13. Final Assembly: Once the PCBs pass inspection, they are ready for component assembly. Surface mount components are placed using pick-and-place machines, and through-hole components are inserted manually or using automated insertion equipment.
  14. Soldering: Components are soldered onto the PCB using reflow soldering or wave soldering techniques, depending on the type of components and assembly requirements.
  15. Testing and Quality Control: The assembled PCBs undergo functional testing to ensure they operate correctly. Additional quality control checks may include visual inspection, X-ray inspection, and automated optical inspection (AOI) to verify solder joints and component placement.
  16. Packaging and Shipping: Once the PCBs pass all tests and quality checks, they are packaged according to customer requirements and shipped to the end destination for integration into electronic devices or further testing.

By following these steps, manufacturers can produce high-quality multilayer R&D PCBs that meet the design specifications and performance requirements of their customers.

  1. Number of Layers: The more layers a PCB has, the more complex and costly it is to manufacture. Each additional layer requires more material and additional processing steps for alignment, lamination, and drilling.
  2. Size of the PCB: Larger PCBs consume more materials and take up more space during manufacturing, which can increase the cost.
  3. Material Used: The type of substrate material (e.g., standard FR-4, high-frequency materials like Rogers), copper thickness, and other material choices impact the cost. Specialty materials cost more but might be necessary for high-performance applications.
  4. Complexity of Design: Complexity includes the density of the board, the number of components, the intricacy of routing, and the presence of special features like blind and buried vias, which require more advanced manufacturing processes.
  5. Surface Finish: Options like HASL, ENIG, and OSP vary in price, with ENIG generally being more expensive but providing better reliability for fine pitch components.
  6. Quantity: Production volume significantly impacts cost. Prototypes are generally more expensive on a per-unit basis because the setup costs are distributed across fewer units. Ordering larger quantities can reduce the cost per PCB.
  7. Turnaround Time: Expedited orders increase costs. Faster turnaround times require prioritizing a specific job over others, potentially incurring overtime or special handling charges.
  8. Testing and Quality Requirements: Additional testing like electrical tests, impedance control, and thermal cycling can add to the cost. Higher standards for quality control and certification (e.g., for aerospace or medical applications) also increase production costs.
  9. Location of Manufacturing: The cost can vary depending on whether the PCBs are manufactured domestically or overseas. Offshore manufacturing might offer lower costs but can add logistics complexity and longer lead times.

To give a rough estimate, a simple 4-layer R&D PCB might cost anywhere from $50 to $200 for a small batch of prototypes, depending on the size and complexity. For more complex 8-layer or 10-layer designs, prices can range from $200 to $500 or more per board in low volumes. These prices can drop significantly in higher volumes.

For the most accurate pricing, it’s best to obtain quotes from several PCB manufacturers, providing them with complete design files and specifications.
