Material preparation: The first step in fabricating organic substrates is to prepare the required substrate materials. Typically, organic substrates use materials such as fiberglass-reinforced resin (FR-4) or high-density interconnect (HDI). These materials must meet specific specifications to ensure their performance and reliability.

Hierarchy design: In the hierarchy design stage, the number of layers of the organic substrate and the function of each layer are determined. This decision-making process requires consideration of factors such as circuit routing, signal transmission requirements, and thermal management.

Graphical Design: Using computer-aided design (CAD) software, engineers create a graphical design of the substrate. This includes routing, connection points, board hierarchy, and component placement.

Lamination and Bonding: In the next step of the manufacturing process, the various substrate layers are put together through a lamination and bonding process. This ensures board stability and connectivity.

Shaping and Drilling: Through processes such as chemical machining and mechanical drilling, manufacturers shape the substrate and create the required openings and connection points.

Copper Foil Covering: Copper foil covering is another critical step that involves coating copper foil on the substrate to make circuit connections.

Etching and Cleaning: Using a chemical etching process, unwanted copper foil is removed, leaving the desired circuit pattern. Then, wash to remove any residue.

Coating and thermal curing: Finally, the substrate is coated to protect the circuit and then thermally cured at high temperatures to ensure the stability of its structure.

Material selection and hierarchy decisions

In the fabrication of organic substrates, the selection of appropriate materials is crucial. Different application fields and performance requirements require different types of substrate materials, such as FR-4 and HDI. Determining the number of layers and hierarchical structure design of the substrate requires a comprehensive consideration of circuit complexity, signal transmission requirements and thermal management.
