What is the manufacturing process of aluminum nitride PCB (AlN PCB)?

The manufacturing process of aluminum nitride PCB (AlN PCB) is a complex and precise process designed to ensure stable performance and reliability of the final product. Here are the main steps in making an AlN PCB:

The first step in making AlN PCB is to prepare the substrate. High-purity aluminum nitride ceramics are often used as substrate materials. Aluminum nitride powder is mixed with a binder and then molded under high temperature and pressure to form a hard substrate.

The surface of the AlN substrate is coated with a layer of conductive material, usually copper foil. Coated copper foil helps form circuit connections and provides good electrical conductivity properties.

The designed circuit pattern is transferred to the surface of the copper foil using photolithography technology. This step involves coating photosensitive resin on copper foil and then forming the desired circuit pattern through a process of exposure and development.

Chemical etching is used to remove the portion of the copper foil that is not covered by the photosensitive resin to form a circuit pattern. This step can achieve precise etching by controlling the concentration and time of the etching solution.

A layer of metal, usually nickel/gold, is deposited over the circuit pattern. The purpose of metallization is to protect the copper foil, prevent it from oxidation, and improve welding performance.

Use laser or mechanical drilling techniques to drill holes into the PCB for insertion of connectors or components. Where necessary, metal inserts are also inserted to provide electrical connections.

After manufacturing is completed, the AlN PCB is subjected to strict testing and quality control. These tests may include electrical testing, reliability testing and visual inspection to ensure that each PCB meets specifications and standards.

The manufacturing process of aluminum nitride PCB requires a high degree of expertise and sophisticated equipment. Through strict quality control and careful process control, manufacturers can ensure the production of high-quality, stable-performance AlN PCBs to meet customer needs for high-performance electronic products.
