What is the 370HR Materials PCB Fabrication Process?

The 370HR is a high-performance FR-4 epoxy resin laminate and prepreg material commonly used for PCB (printed circuit board) fabrication, especially in applications requiring high thermal reliability and robust electrical properties. The fabrication process for PCBs using 370HR materials involves several steps, tailored to make the most of the material’s properties for durable and efficient electronic boards. Here’s a general overview of the process:

  1. Material Selection: Choosing the right 370HR laminate thickness and prepreg options based on the application’s specific thermal and mechanical requirements.
  2. Design and Layout: PCB design is created with appropriate CAD software, considering all the necessary guidelines for using 370HR materials to ensure optimal performance.
  3. Photolithography: The design is transferred onto the 370HR material using a light-sensitive chemical photoresist applied to the laminate. Ultraviolet light is used to expose the pattern of the circuit, which is then developed to remove unexposed photoresist.
  4. Etching: The exposed areas of copper are chemically etched away, leaving behind the circuit pattern. This step requires careful control to ensure precise trace definitions, crucial for maintaining signal integrity.
  5. Layering and Lamination: For multilayer PCBs, individual layers of 370HR prepreg are stacked and aligned with copper foils between each layer. The stack is subjected to heat and pressure in a lamination press to cure the epoxy resin, bonding the layers into a single solid structure.
  6. Drilling: Post-lamination, holes are drilled to place vias and mount components. This step must be precisely controlled to avoid damaging the internal layers of the PCB.
  7. Plating: The drilled holes are electroplated with copper to establish connections between the layers in multilayer PCBs. This step enhances the electrical connectivity and adds mechanical strength to the vias.
  8. Solder Mask Application: A solder mask is applied over the entire PCB surface except for the pads where components will be soldered. This layer protects the copper from oxidation and prevents solder bridging between closely spaced pads.
  9. Silkscreen: Component labels and other markings are printed on the solder mask layer, facilitating easier assembly and maintenance.
  10. Surface Finish: The PCB receives a surface finish, such as HASL (Hot Air Solder Leveling), ENIG (Electroless Nickel Immersion Gold), or others, to enhance the solderability and protect against corrosion.
  11. Testing and Inspection: The completed PCBs are tested for functionality and inspected for any defects. Methods like Automated Optical Inspection (AOI), X-ray inspection, and electrical testing are commonly used.
  12. Final Cutting and Packaging: Finally, the PCBs are routed or scored to separate them into individual boards and packaged for shipping.

Each step in the PCB fabrication process using 370HR materials is crucial for ensuring that the final product meets the required specifications and performs reliably in its intended application. The choice of 370HR specifically aids in achieving higher thermal stability and mechanical robustness, making it suitable for more demanding electronic applications.

  6. Film Printing: Use the Gerber files to create photoresist films for the PCB layers. These films contain the circuit pattern and are used in the etching process.
  7. Inner Layer Processing: Process the inner layers of the PCB stack-up using 370HR material. This involves cleaning, applying photoresist, exposing the circuit pattern onto the copper layer using the film, developing the pattern, and etching away the unwanted copper.
  8. Layer Alignment and Bonding: Align and bond the processed inner layers together to form a multi-layer PCB stack-up using 370HR material. Use adhesives or prepreg materials to bond the layers together.
  9. Drilling: Drill precision holes for through-hole components and vias through the entire stack-up of 370HR material according to the design specifications.
  10. Plating: Plate the drilled holes with copper to create conductive pathways for electrical connections. This may involve electroplating or chemical deposition processes.
  11. Outer Layer Processing: Process the outer layers of the PCB stack-up using 370HR material. Apply photoresist, expose the pattern, develop, and etch away the unwanted copper.
  12. Solder Mask Application: Apply a solder mask layer to the PCB surface to protect the copper traces and prevent solder bridging during assembly. Create openings in the solder mask for component pads and vias.
  13. Surface Finish: Apply a surface finish to the exposed copper pads to improve solderability and prevent oxidation. Choose a surface finish compatible with 370HR material.

How much should a 370HR Materials PCB cost?

The cost of a 370HR material PCB can vary depending on several factors, including the size, complexity, quantity, and specifications of the board, as well as the chosen fabrication and assembly processes. However, I can provide a rough estimate based on industry standards and typical considerations.

For small quantities (prototypes or low volume production), the cost per board can range from $10 to $100 or more, with larger and more complex boards generally costing more. This estimate includes the cost of materials, fabrication processes (such as layer processing, drilling, plating, and surface finishing), testing, and overhead expenses for the PCB manufacturer.

For larger quantities (high volume production), the cost per board typically decreases due to economies of scale. High volume orders may be priced in the range of a few dollars to tens of dollars per board, depending on the volume, complexity, and negotiation with the manufacturer.

It’s important to note that these estimates are rough approximations, and the actual cost of a 370HR material PCB can vary based on specific project requirements, supplier pricing, geographical location, and other factors. Additionally, additional costs may apply for services such as design verification, engineering support, expedited manufacturing, and shipping.

To get an accurate cost estimate for your project, it’s recommended to request quotes from multiple PCB manufacturers and provide detailed specifications and quantities for your PCB design. This allows manufacturers to provide tailored pricing based on your specific requirements and volume needs.
