Transition: lessons learned in the development and production of IBM´s μLaminateTM PBGA

This paper describes challenges encountered in the development of IBM´s μLaminate^TM PBGA. The implementation of a new product line was based on the factories in place to ramp production with extensions to base technology. Lessons learned in the product development are focused to provide an introspective look at organization and approaches. Solutions to the challenges cited are specific to the IBM product line and structure of the Endicott and Bromont facilities, but are also inherent to the PBGA product itself and should be applicable to other tools and designs. Specific areas discussed include the product development process vehicle decisions, the laminate development and ramp, bond and assembly development, and concludes with recommendations from the experience
