What is the manufacturing process for Microvia Substrates?

The manufacturing process of Microvia Substrates is a complex and precise process that requires multiple critical steps and special processes and measures to ensure the quality and performance of the final product.

The first step in manufacturing Microvia Substrates is to prepare the substrate, typically using fiberglass-reinforced epoxy resin. The substrate is then surface coated so that subsequent printed circuit layers can adhere to its surface.

The next step is to drill holes into the substrate to form Microvia holes. These pores are usually very small, ranging from tens to hundreds of microns in diameter. After drilling is completed, fill the Microvia hole with filler material to ensure the reliability of the electrical connection within the hole.

Next, a circuit layer is printed on the surface of the substrate, usually using a photolithography process to transfer the pattern to the surface of the substrate. Then, unnecessary parts are removed through chemical etching, allowing the desired circuit pattern to be formed.

After the circuit pattern is completed, the Microvia Substrates need to be metallized to create conductive paths on the circuit pattern. Commonly used metallization methods include electroless copper plating or vacuum deposition of copper. Finally, the Microvia Substrates surface is coated to improve its corrosion resistance and weldability.

Manufacturing Microvia Substrates requires highly precise processing equipment and processes to ensure that the size and location of Microvia holes meet design requirements. This involves high-precision drilling and patterning processes.

During the manufacturing process of Microvia Substrates, environmental conditions need to be strictly controlled, including factors such as temperature, humidity, and dust. This helps ensure the stability of the production process and consistent product quality.

After each manufacturing step is completed, strict quality inspections are required to ensure that the quality of Microvia Substrates meets standards. This includes checking aspects such as aperture size, circuit pattern integrity, and metallization layer uniformity.

Manufacturing Microvia Substrates is a continuous improvement process that requires continuous optimization of processes and technologies to improve product quality and production efficiency. This requires manufacturers to continue R&D and experimentation to respond to changing market demands and technical challenges.

In the process of manufacturing Microvia Substrates, the above key steps and special processes and measures are key factors in ensuring the quality and performance of the final product. By strictly controlling each manufacturing step and using advanced technology and processes, high-quality, reliable Microvia Substrates can be produced to meet the needs of different electronic devices.

What are the specific manufacturing steps for Microvia Substrates?

The manufacturing process of Microvia Substrates involves multiple critical steps, each of which is critical and directly affects the quality and performance of the final product. Below we will introduce the specific manufacturing steps of Microvia Substrates in detail:

First, the substrate for manufacturing Microvia Substrates needs to be prepared. Glass fiber reinforced resin is usually selected as the substrate. A layer of special adhesive is then applied to the surface of the substrate to ensure a strong bond between subsequent layers.

Next, microvia holes are formed by drilling holes into the substrate using laser drilling or mechanical drilling techniques. The diameter of these Microvia holes usually ranges from tens to hundreds of microns. The holes are then filled with a conductive material, usually copper or another metal, to create a conductive path.

After the Microvia holes are filled, the next step is the printed circuit layer. The desired circuit pattern is formed by covering the surface of the substrate with a layer of conductive material, usually copper foil, and using chemical etching techniques to remove excess copper. This step determines the wire and connection structure of the Microvia Substrates.

Finally, metallization and surface coating are performed to protect the surface of Microvia Substrates and improve its corrosion resistance. By plating the surface with a layer of metal, such as nickel, gold or tin, and covering it with a protective polymer coating, Microvia Substrates ensure good electrical conductivity and mechanical strength, as well as durability and stability.

The above are the main steps of the manufacturing process of Microvia Substrates.
