What is the RO4350B PCB Fabrication Process?

The fabrication process for RO4350B PCBs follows standard PCB manufacturing procedures, with some considerations specific to the properties of RO4350B material. Here’s an overview of the typical fabrication process:

  1. Material Preparation:The fabrication process begins with the procurement of RO4350B laminate material in the desired thickness and copper foil type (typically rolled annealed copper). The laminate sheets are inspected for any defects before proceeding to the next steps.
  2. Preparation of Gerber Files:PCB designers create Gerber files containing the PCB layout, including the placement of copper traces, vias, pads, and other features. These files define the design of the PCB and are used by the manufacturer during fabrication.
  3. Prepreg and Core Layer Preparation:In multilayer PCBs, prepreg layers (layers of uncured resin with fiberglass reinforcement) and core layers (layers of cured resin with copper foil) are prepared according to the stackup design. RO4350B laminate material is typically used as core layers due to its high-frequency performance.
  4. Copper Cladding:Copper foil is laminated onto both sides of the RO4350B core layers using heat and pressure. The thickness of the copper foil is determined based on the required copper weight specified in the design.
  5. Laser Drilling:Holes for vias and through-hole components are drilled using laser drilling equipment. Laser drilling provides high precision and accuracy, essential for high-frequency applications.
  6. Through-Hole Plating:Through-holes are plated with conductive material (usually copper) to establish electrical connections between different layers of the PCB. This process is typically performed using electroplating techniques.
  7. Circuit Patterning: A layer of photoresist is applied to the copper-clad laminate, and the Gerber files are used to selectively expose the photoresist to UV light. The exposed areas are then developed, leaving behind the desired copper traces and features.
  8. Etching:The exposed copper is etched away using chemical processes, leaving behind the circuitry defined by the photoresist mask.
  9. Surface Finishing:Surface finish options such as HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or OSP (Organic Solderability Preservatives) may be applied to protect the exposed copper and improve solderability.
  10. Final Inspection and Testing:The fabricated PCB undergoes inspection to ensure that it meets the design specifications and quality standards. Electrical testing may be performed to verify continuity, impedance, and other electrical parameters.
  11. Routing and Profiling:Individual PCBs are routed out of the larger panel using milling or routing equipment. The edges are then smoothed, and any remaining copper burrs are removed.
  12. Quality Control and Packaging:The finished PCBs are subjected to final quality control checks before being packaged and prepared for shipment to the customer.

Throughout the fabrication process, it’s essential to follow best practices for handling and processing RO4350B material to ensure optimal performance in high-frequency applications. Additionally, collaboration between PCB designers and manufacturers is crucial to address any specific requirements or challenges associated with the material.

How do you manufacture an RO4350B PCB?

Manufacturing an RO4350B PCB involves several steps, from material selection to final testing. Here’s a detailed overview of the manufacturing process:

  1. Material Selection:Choose RO4350B laminate material from a trusted supplier like Rogers Corporation. Consider the required thickness, copper foil thickness, and any special characteristics needed for the application.
  2. Panel Preparation:Cut the RO4350B material into panels of the required size for the PCBs to be fabricated. Ensure that the panels are clean and free from contaminants.
  3. Preparation of Design Files: Design the PCB layout using CAD (Computer-Aided Design) software. Include all necessary elements such as traces, pads, vias, and components. Generate Gerber files, drill files, and other manufacturing data required for fabrication.
  4. Panelization:Arrange multiple PCB designs on a panel to maximize material usage and facilitate efficient manufacturing. Add fiducial marks and tooling holes for alignment during fabrication.
  5. Drilling:Use precision CNC drilling machines to drill holes for vias and component mounting pads according to the design specifications. Ensure accurate hole placement and size.
  6. Copper Deposition:Apply a thin layer of copper to the panel surfaces using an electroplating process. This step forms the conductive layers of the PCB.
  7. Circuit Patterning: Apply a layer of photoresist material to the copper-clad panels. Use photolithography techniques to expose the photoresist layer to UV light through a mask containing the PCB pattern. Develop the exposed photoresist to reveal the desired copper traces and pads.
  8. Etching:Immerse the panels in an etchant solution to remove the exposed copper and define the circuit traces and pads. Rinse the panels thoroughly to remove any remaining etchant.
  9. Surface Finish:Apply a surface finish to protect the exposed copper surfaces, improve solderability, and prevent oxidation. Common surface finishes for RO4350B PCBs include immersion gold, ENIG (Electroless Nickel Immersion Gold), and HASL (Hot Air Solder Leveling).
  10. Solder Mask Application: Apply a solder mask layer over the entire panel, leaving openings for solder pads and vias. Cure the solder mask to harden it and protect the copper traces from environmental factors and solder bridging during assembly.
  11. Silkscreen Printing: Print component outlines, reference designators, and other identification marks onto the PCB surface using silkscreen printing techniques. This information aids in assembly and inspection.
  12. Testing and Inspection:Conduct electrical testing to verify the continuity and integrity of the circuit traces. Perform visual inspection to check for defects such as misalignment, solder bridges, or missing features.
  13. Routing and Separation: If multiple PCBs are fabricated on a single panel, separate (route) them into individual boards using CNC routing machines. Clean the boards to remove any debris from the manufacturing process.
  14. Final Testing:Perform final electrical testing to ensure that the fabricated PCBs meet the specified performance criteria and functional requirements.
  15. Packaging and Shipping:Package the finished PCBs securely to prevent damage during transit. Label the packages with relevant information and ship them to the customer or assembly facility.

Throughout the manufacturing process, strict quality control measures should be implemented to ensure the reliability and performance of the RO4350B PCBs. It’s essential to follow the manufacturer’s recommended fabrication guidelines and best practices to achieve optimal results.
