Develop a procedure to allow periodic removal of CSP devices to evaluate residues. Maintain accurate and long-term test data and periodically assess CSP device trending. Develop scanning acoustical microscopy for reliability assessment. Deploy fine-resolution metrology for dimensional size analysis. Develop a mechanical strength model for assessing CSP bond reliability.
Training Develop a certification plan limited to qualified production personnel.
Design closed-loop training that accounts for personnel feedback. Although CSP is capturing much attention for use in performance-driven SFF medical product applications, its implementation presents challenges. In addition, FDA's design control regulations increase the complexity and risk of designing devices using this technology. To achieve the most success with CSP in medical products, manufacturers should institute concurrent engineering, which enables the collaboration of design and development personnel with manufacturing services. Early concurrent engineering can minimize scheduling conflicts, manufacturing costs, and reliability concerns, and help ensure product development success.
