Design for Reliability
New products are only approved for production after undergoing the CML Micro approved formal design process that has been certified to ISO 9001:2015.
A design authority is allocated at the conceptual stage of the project. This person is responsible for the technical aspects of the design, both throughout the design stages and during the lifetime of the product.
Design rules automatically check and ensure that IC layouts comply with the appropriate requirements for the design and technology.
Design verification includes automated simulation, design checking, layout checking, evaluation of prototypes and characterisation.
Design reviews are held at critical stages throughout the design. This ensures that all necessary requirements have been met before continuing on to the next stage of the design process.
Manufacture for Reliability
Package manufacturing is carried out at the CML Micro assembly facility certified to ISO 9001:2015 or by similarly qualified outside sources.
A process owner is allocated to each process used within the CML Micro production life cycle. The person is responsible for all process qualification and approval.
The CML Micro Quality Managers are responsible for ensuring that reliability qualification tests are planned, carried out, and any problems resolved.
