Was ist das ABF Substrate Herstellungsprozess?

The ABF (Ajinomoto Build-up Film) substrate fabrication process involves several key steps to create high-performance printed circuit boards (Leiterplatten) with advanced capabilities. Here is an overview of the ABF substrate fabrication process:

1. Preparation of Base Material: The fabrication process begins with the selection and preparation of the base material. Typically, this involves a copper-clad laminate that will serve as the foundation for the build-up layers. The base material is cleaned and treated to ensure proper adhesion of subsequent layers.
2. Application of Build-Up Film: ABF build-up film is applied to the base material in thin layers. The film is a key component of the substrate, providing dielectric properties that support high-density interconnects. The film is carefully aligned and laminated onto the base material using heat and pressure.
3. Fotolithografie: After the build-up film is applied, a photolithography process is used to define the circuit patterns. A photoresist layer is coated onto the film, and ultraviolet (UV) light is used to expose and develop the photoresist, creating the desired circuit patterns.
4. Radierung: The exposed areas of the build-up film are then etched away to create the necessary circuit patterns. This involves using chemical etchants to remove unwanted material, leaving behind the defined circuitry.
5. Formation of Vias: Vias are essential for creating vertical connections between different layers of the substrate. The fabrication process includes drilling or laser ablation to create vias through the build-up film layers. The vias are then plated with metal to form electrical connections.
6. Electroless and Electroplating: After forming vias, electroless plating is used to deposit a thin layer of metal onto the inner surfaces of the vias. This is followed by electroplating to build up the metal thickness and ensure strong electrical connections. The metal plating process typically involves copper, but other metals may be used depending on the requirements.
7. Layer Build-Up: Additional layers of ABF film are applied and processed in a similar manner as the initial layers. This build-up process continues until the desired number of layers is achieved, allowing for complex and high-density circuit designs.
8. Final Etching and Patterning: Once all layers are built up, a final etching process is used to refine and complete the circuit patterns. This step ensures that all layers are correctly aligned and that the final circuitry meets design specifications.
9. Inspection and Testing: The fabricated ABF substrate undergoes rigorous inspection and testing to ensure it meets performance and quality standards. This includes electrical testing, visual inspection, and thermal analysis to confirm that the substrate functions correctly and reliably.
10. Cutting and Finishing: The final step involves cutting the substrate into the desired shapes and sizes. Additional finishing processes may include applying solder mask layers, surface finishes, and preparing the substrate for final assembly.
