The IPC-9191 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
The primary goal of IPC-9191 is to help organizations reduce process variation. It emphasizes that preventing a defect is significantly more cost-effective than finding and fixing one after production. ipc9191 pdf
