What is the ABF Package Substrate Fabrication Process?

The fabrication process of ABF (Ajinomoto Build-up Film) Package Substrates involves several key steps to achieve the desired electrical, thermal, and mechanical properties:

  1. Material Preparation:Select and prepare the substrate materials, typically polyimide films and copper foils. These materials should meet the specified electrical and mechanical requirements.
  2. Layer Lamination:Start by laminating multiple layers of polyimide films together with adhesive bonding films (typically thermosetting resins). This forms the basic substrate structure with alternating insulating and conductive layers.
  3. Laser Drilling: Use laser drilling techniques to create vias (holes) through the substrate layers where electrical connections are needed. This process ensures precise placement and minimal damage to surrounding materials.
  4. Via Formation: Plate the vias with conductive material (usually copper) to establish electrical connections between different layers. The plating process can involve several steps, including surface activation, electroless plating, and electrolytic plating.
  5. Circuit Patterning: Apply photoresist and use photolithography techniques to define circuit patterns on the substrate’s surface. Etch away excess copper to form the desired conductive traces and pads.
  6. Surface Finish: Apply a surface finish to protect the copper traces from oxidation and to facilitate soldering during assembly. Common surface finishes include ENIG (Electroless Nickel Immersion Gold), OSP (Organic Solderability Preservatives), and HASL (Hot Air Solder Leveling).
  7. Quality Control and Testing: Conduct rigorous quality checks throughout the fabrication process. Inspect for defects such as shorts, opens, and dimensional inaccuracies. Test the substrate for electrical continuity, insulation resistance, and thermal performance.
  8. Final Inspection and Packaging: Once fabrication is complete and the substrates pass quality control tests, package them appropriately to protect against contamination and damage during storage and transportation.

By following these steps, manufacturers can produce ABF package substrates that meet the stringent requirements of high-performance electronic applications, ensuring reliability and consistency in electrical connectivity and thermal management.

How do you manufacture ABF Package Substrate?

Manufacturing ABF (Ajinomoto Build-up Film) Package Substrates involves a series of intricate processes designed to create high-performance, reliable substrates for advanced semiconductor packaging. Here’s a detailed overview of the manufacturing process:

  1. Material Selection and PreparationBegin by selecting high-quality polyimide films and copper foils. The polyimide films serve as the insulating layers, while copper foils provide the conductive paths. These materials are chosen based on their electrical properties, thermal stability, and mechanical strength.
  2. Layer Lamination:The manufacturing process starts with layer lamination. Polyimide films are stacked together with bonding films (adhesive layers) between them. These bonding films, often thermosetting resins, are essential for creating strong, durable bonds between the polyimide layers. The stackup configuration is determined based on the substrate’s required number of signal and plane layers.
  3. Laser Drilling:After lamination, the next step is laser drilling. High-precision lasers are used to drill microvias or through-holes (vias) through the layered substrate. These vias will later be filled with conductive material to establish electrical connections between different layers. Laser drilling ensures precise placement and minimal thermal damage to the substrate materials.
  4. Via Formation:Following laser drilling, the vias are processed to make them conductive. The vias are typically electroplated with copper to form a conductive pathway from one layer to another. This involves several steps:

   – Surface Activation: The inner walls of the vias are activated to promote adhesion of the subsequent copper layers.

   – Electroless Copper Deposition: A thin layer of copper is deposited over the activated surface to initiate the plating process.

   – Electrolytic Copper Plating: Copper is electrodeposited into the vias to build up sufficient thickness for electrical conductivity.

  1. Circuit Patterning:Once vias are formed and plated, the substrate undergoes circuit patterning. A photoresist layer is applied and exposed to UV light through a photomask, defining the circuit patterns. The exposed areas are then etched away to reveal the copper traces and pads that will carry electrical signals and connections.
  2. Surface Finish Application:After circuit patterning, a surface finish is applied to protect the exposed copper traces and pads. Common surface finishes include:

   – ENIG (Electroless Nickel Immersion Gold): Provides excellent oxidation resistance and solderability.

   – OSP (Organic Solderability Preservatives): Protects copper surfaces from oxidation prior to assembly.

   – HASL (Hot Air Solder Leveling): Applies a layer of solder to facilitate soldering during assembly.

  1. Quality Control and Testing:Throughout the manufacturing process, rigorous quality control measures are implemented. Inspections are conducted to detect defects such as shorts, opens, and dimensional inaccuracies. Electrical testing verifies the substrate’s functionality, ensuring proper connectivity and insulation resistance.
  2. Final Inspection and Packaging:Once fabrication is complete and quality tests are passed, the ABF package substrates undergo final inspection. They are carefully packaged to protect against contamination and physical damage during storage and transportation to assembly facilities.
  3. Assembly and Integration:ABF package substrates are then assembled with semiconductor devices using advanced packaging techniques such as flip-chip bonding or wire bonding. They provide essential electrical interconnections and thermal management for integrated circuits, ensuring reliable performance in demanding applications.

By following these detailed manufacturing processes, manufacturers produce ABF package substrates that meet the stringent requirements of high-performance electronic devices, contributing to advancements in semiconductor technology and electronic product miniaturization.
