What is the manufacturing process for Microvia Substrates?

Microvia Substrates’ manufacturing process is complex and sophisticated, involving a series of critical steps and special processes to ensure the quality and reliability of the final product. The manufacturing process of Microvia Substrates will be analyzed in detail below, let us understand it in depth.

The first step in manufacturing Microvia Substrates is to prepare the substrate. Glass fiber reinforced epoxy resin is usually used as the base material, and its surface requires special treatment to improve adhesion. Next, the surface of the substrate is coated with copper foil to form a conductive layer for subsequent circuit layer printing.

One of the features of Microvia Substrates is its microvias, which are used to connect circuits at different levels. In this step, Microvia holes are drilled into the substrate using laser drilling technology and a special filling material, usually copper or polyimide resin (PI), is coated inside the hole to ensure good connection and insulation.

After the Microvia holes are filled, the circuit layer will be printed. The desired circuit layout is formed by covering the printed circuit pattern on the surface of the copper foil and using chemical etching to remove the uncovered copper foil. This step requires precise control and processing to ensure the accuracy and clarity of the circuit pattern.

The final step is to metallize and surface coat the manufactured Microvia Substrates. Metallization usually uses electroplating technology to deposit a metal layer on the surface of the circuit layer and Microvia hole to enhance its conductivity and corrosion resistance. Next, a protective coating is applied to the surface of Microvia Substrates to protect it from environmental influences and physical damage.

Drilling of Microvia holes is one of the key steps in the manufacturing of Microvia Substrates. Using laser drilling technology can achieve tiny hole diameters and high precision, ensuring the quality and reliability of Microvia.

The chemical etching process requires precise control and monitoring to ensure correct circuit patterning and avoid unnecessary etching errors. Precise process parameters and real-time monitoring equipment are the key to ensuring the quality of chemical etching.

The electroplating process is used to enhance the conductivity and corrosion resistance of the Microvia Substrates surface and requires strict control of the composition and temperature of the plating solution to ensure uniform metal deposition and good coating quality.

Microvia Substrates’ manufacturing process requires a high degree of expertise and technology to ensure the quality and performance of the final product meet requirements.
