These materials are chosen for their high thermal conductivity and electrical insulation properties, crucial for efficient heat dissipation and reliable electrical performance.
  2. Green Sheet Preparation: Ceramic powders are mixed with binders and other additives to form a slurry, which is then cast or extruded into thin sheets known as green sheets. These green sheets are flexible and contain the ceramic material in a binder matrix.
  3. Layer Stacking: Multiple green sheets are stacked together, with each layer containing circuit patterns and vias designed using screen printing or photolithography techniques. Conductive materials such as metal pastes (e.g., silver, copper) are used to create the circuit traces and pads.
  4. Lamination:The stacked green sheets are laminated under pressure to bond them together into a monolithic structure. This process removes air and ensures good adhesion between layers.
  5. Via Formation: Vias are formed by drilling or punching through the laminated stack to connect conductive layers vertically. These vias serve both as electrical connections between layers and as pathways for thermal dissipation.
  6. Firing (Co-Firing): The crucial step in Mitsubishi BT Substrate fabrication is co-firing. The entire laminated structure undergoes a high-temperature firing process in a controlled atmosphere kiln. During firing, the green sheets are sintered to form a dense ceramic substrate, and the conductive materials are sintered to form continuous conductive paths.
  7. Surface Finishing: After firing, the substrate surfaces may undergo processes such as polishing or metallization to prepare them for component attachment and soldering.
  8. Quality Control and Testing: Throughout the fabrication process, stringent quality control measures are employed to ensure dimensional accuracy, material purity, and adherence to electrical and thermal specifications. Testing may include checks for electrical continuity, thermal conductivity, mechanical strength, and reliability under various environmental conditions.
