Titanium: Known for its high strength-to-weight ratio, corrosion resistance, and biocompatibility.

Protective Coatings: Coatings such as anodization for aluminum, passivation for stainless steel, and other surface treatments are applied to enhance durability and performance.

What Size are Metallic Substrates?

The size of metallic substrates varies depending on the application and specific design requirements:

Thickness: The thickness of metallic substrates can range from a few hundred micrometers to several millimeters, depending on the thermal and mechanical requirements.

Dimensions: The length and width of the substrates are determined by the size of the components and the layout of the system. They can range from small form factors for compact devices to larger substrates for complex electronic systems.

The Manufacturing Process of Metallic Substrates

The manufacturing process of metallic substrates involves several precise and controlled steps to ensure high quality and performance:

High-quality metal sheets or plates are selected and prepared for processing. The metal is cleaned and treated to remove any impurities and ensure a smooth surface.

The metal is cut and shaped to the desired dimensions using techniques such as laser cutting, water jet cutting, or stamping. This step ensures that the substrate meets the specific size and shape requirements of the application.

The surface of the metal is treated to enhance its properties. This can include anodization, passivation, or other surface treatments to improve corrosion resistance, thermal conductivity, and electrical performance.

Conductive and insulating layers are deposited onto the metal substrate using techniques such as sputtering, electroplating, or screen printing. These layers form the electrical pathways and insulation required for the specific application.

After fabrication, the substrate is assembled with any necessary components and connectors. Rigorous testing is conducted to ensure that the substrate meets all design specifications and performance requirements. This includes testing for thermal conductivity, electrical performance, and mechanical integrity.
