1. Selección de materiales:Choose an appropriate substrate material based on the required electrical, termal, y propiedades mecánicas. Common materials include high-frequency laminates, ceramics, and advanced composites.
2. Material Preparation: Process the selected material into sheets or panels of the desired thickness. Esto puede implicar cortes, polishing, and conditioning the substrate to meet specific design requirements.
3. Photoresist Coating: Apply a photoresist layer to the substrate. This is a light-sensitive material used to create patterns on the substrate. The photoresist is typically applied using spin coating or roller coating techniques to achieve a uniform layer.
4. Transferencia de patrones: Expose the photoresist to ultraviolet (UV) light through a photomask that contains the desired circuit pattern. This step transfers the circuit design onto the photoresist layer. The areas of the photoresist exposed to UV light undergo a chemical change, making them either soluble or insoluble in the developer solution.
5. Development: Develop the exposed photoresist to reveal the pattern. This involves immersing the substrate in a developer solution that removes the soluble photoresist, leaving behind the desired pattern on the substrate.
6. Aguafuerte: Use etching techniques to remove material from the substrate where the photoresist was removed. This step creates the actual circuit pattern on the substrate. Etching can be done using wet etching (chemical solutions) or dry etching (plasma-based methods), depending on the substrate material and required precision.
7. Photoresist Removal: Strip away the remaining photoresist to reveal the final circuit pattern on the substrate. This is usually done with a photoresist stripper or solvent.
8. Via and Plating: If the design includes vias (holes that connect different layers of the substrate), drill or laser them and then plate them with metal to establish electrical connections. This may involve processes such as electroless plating or electroplating.
9. Lamination: For multilayer substrates, laminate additional layers onto the base substrate. This involves applying adhesive and heat to bond multiple layers together, forming a multi-layered circuit board.
10. Pruebas e inspección: Conduct thorough testing and inspection of the fabricated substrate. This includes checking for defects, measuring electrical properties, and verifying that the substrate meets design specifications.
11. Final Processing:Perform any additional processes required to finalize the substrate, such as cutting to size, applying surface finishes, or adding solder masks and other protective layers.
12. Packaging: Package the finished substrates for shipment and integration into electronic systems. This may involve protective packaging to prevent damage during transport and handling.

Each of these steps is critical in ensuring that the millimeter wave substrate performs effectively at high frequencies, meeting the stringent requirements of advanced communication systems, radar applications, and other high-tech electronic devices.
