The first step in manufacturing Microvia Substrates is to prepare and process the substrate. Typically fiberglass reinforced epoxy is used as the base material to provide adequate strength and insulation. At this stage, it is necessary to ensure the flatness and cleanliness of the substrate surface so that subsequent processes can proceed smoothly.

After the substrate preparation is completed, the next step is the graphic design and layer production of Microvia Substrates. This involves converting the designed circuit diagram into a graphics layer through CAD software and printing it on the substrate surface. This step is important to ensure that Microvia Substrates function and connect correctly.

Microvia in Microvia Substrates is an important part of connecting circuits at different levels. In this step, laser drilling technology is used to drill holes into the substrate, which is then filled with conductive material (usually copper) to ensure the Microvia’s conductivity and connectivity. This process requires a high degree of precision and skill to ensure the Microvia’s size and position are precise.

After the Microvia is drilled and filled, the next step is electroplating. This step involves plating a layer of metal, usually copper, on the surface of the substrate and inside the Microvia. Electroplating enhances Microvia’s electrical conductivity and connection strength while protecting its surface from the effects of oxidation and corrosion.

After completing the Microvia processing, the next step is to print the circuit layer on the surface of the substrate.
