2. Printing of Conductive and Dielectric Layers: Conductive and dielectric pastes are screen-printed onto the green tapes to create the desired circuit patterns. Conductive paste contains metals such as silver, gold, or copper, while dielectric paste provides insulation between conductive traces.
3. Layer Stacking: Multiple layers of green tapes with printed patterns are stacked together to form the complete substrate structure. Alignment of the layers is critical to ensure proper interconnection between conductive traces and vias.
4. Расслоение:The stacked green tape layers are then subjected to high pressure and temperature in a lamination process. This compresses the layers together, removing any air gaps and bonding them into a solid structure.
5. Формирование переходных отверстий: After lamination, small holes are drilled or punched through the substrate at designated locations for vias. These vias will later provide vertical interconnection between different layers of the substrate.
6. Обжиг: The substrate undergoes a firing process in a kiln at high temperatures (typically above 1000°C) to sinter the ceramic material and remove organic binders from the green tapes. This transforms the substrate into a dense, ceramic structure with embedded conductive traces.
7. Conductor Plating: After firing, the vias are typically filled with conductive material through processes such as electroplating or screen printing. This ensures electrical continuity between different layers of the substrate.
8. Surface Finishing:The substrate surface may undergo additional processing such as grinding, polishing, or coating with protective layers to improve flatness, surface quality, and solderability.
9. Final Inspection and Testing: The finished MCS undergoes inspection and testing to ensure adherence to design specifications, including dimensional accuracy, electrical continuity, and insulation resistance.
10. Packaging and Assembly: Once validated, the MCS can be packaged and assembled with electronic components such as integrated circuits, resistors, capacitors, and inductors to create functional electronic devices.
