The document is structured into several key sections that guide a company through the lifecycle of SPC implementation:
While IPC-9191 provides the general roadmap, it is often used in conjunction with specialized application guides: Application General Foundation Framework for all electronics manufacturing. IPC-9192 Base Materials Laminate and prepreg manufacturing. IPC-9193 PCB Fabrication Etching, plating, and lamination. IPC-9194 PCB Assembly (PBA) SMT and through-hole assembly processes. IPC-9199 Tool for assessing an existing SPC system. Where to Find the PDF
The standard, titled "General Guidelines for Implementation of Statistical Process Control (SPC)" , is a foundational document for electronics manufacturers looking to shift from traditional defect detection to proactive defect prevention. Published in November 1999, it supersedes the earlier IPC-PC-90 and harmonizes electronics-industry requirements with the international ISO 11462-1 standard. Overview of IPC-9191 ipc9191 pdf
: Training employees to use Control Charts and creating detailed work instructions for corrective actions. The IPC-91xx Family of Standards
: Using tools like control charts and histograms to distinguish between normal process variation and "special cause" disturbances. Core Elements of the Standard The document is structured into several key sections
The primary goal of IPC-9191 is to increase production efficiency and reduce costs by minimizing variation across all processes—from initial design to final servicing. It provides a comprehensive framework for:
: Critical for establishing a quality-focused organizational structure and a clear action plan. IPC-9194 PCB Assembly (PBA) SMT and through-hole assembly
You can obtain the through several official and authorized industry platforms:
: Mapping processes to identify critical parameters, such as solder paste height or plating thickness.
: Outlining management responsibilities, including resource allocation and strategic planning for quality.
