Core Manufacturing Challenges
1. High difficulty in fine line and space processing: Line width/space is often less than 0.1mm, requiring high-precision etching processes, which are prone to uneven line width, short circuits, or open circuits.
2. Complex multi-layer interconnection process: With more layers (usually 8 or more) and the need for microvia, blind via, and buried via technologies, the requirement for drilling alignment is extremely high, making hole position deviation or poor metallization likely.
3. Difficult impedance control: The high-density wiring and multi-layer structure result in complex signal transmission paths, requiring precise impedance matching to avoid signal reflection and interference.
4. Strict material selection and compatibility requirements: Special substrates with low loss and high temperature resistance must be used, and the thermal expansion coefficients of different materials need to match to prevent interlayer separation.
5. Difficult quality inspection and defect control: Tiny line defects, hole wall defects, etc., are hard to detect through conventional testing, imposing high requirements on testing equipment and process control.
