An object-oriented automated SPC analysis and reporting system for powder manufacturing in the specialty chemical plants

This paper addresses a method for automating the process of generating statistical process control summaries for powder manufacturing in an epoxy molding compound for encapsulation (EME) plant by integrating the capabilities of WinSPC/sup /spl reg//, Microsoft/sup /spl reg// SQL Server database and Microsoft's ActiveX/sup /spl reg// Data Objects (ADO). The system allows for not only real-time SPC analysis and reporting of daily production lots, but also monthly SPC analysis and reporting using a user-friendly graphical users interface.
