CPO Packaging & Assembly
The real bottleneck for CPO is the Active Alignment process. Precision 6-DOF alignment where robots fine-tune positioning with laser feedback is essential. Process know-how that cannot be replicated by simply purchasing equipment serves as a moat. ficonTEC leads the market, while MRSI (Mycronic) pursues with sub-micron die bonding. TSMC COUPE has emerged as the de facto standard for CPO optical engines.
