The IPC-9191 framework adapts perfectly to this environment:
serves as the electronics manufacturing industry's standard blueprint for Statistical Process Control (SPC) . Released by the IPC Association , this comprehensive guideline establishes the organizational infrastructure, mathematical frameworks, and technical execution strategies required to build a defect-preventative manufacturing environment. Rather than filtering out defects during end-of-line inspections, IPC-9191 shifts the focus toward continuous variation reduction throughout the production lifecycle.

Understanding IPC-9191: The Blueprint for Statistical Process Control in Electronics Manufacturing ipc9191 pdf
Used for measurable physical properties (e.g., solder paste deposition height, plating thickness). These include X-bar and R charts (Mean and Range) or X-bar and S charts (Mean and Standard Deviation).
You can search for these papers on academic databases like Google Scholar, ResearchGate, or Academia.edu. Some of these papers might be available in PDF format for free, while others may require a subscription or a one-time payment. The IPC-9191 framework adapts perfectly to this environment:

Run continuous data monitoring against live charts. If a data point breaches a control limit or displays an unnatural trend (e.g., seven consecutive points climbing toward a limit), operators pause the line to identify the special cause. The Evolution and Core Philosophy of IPC-9191 Understanding
Establishing cross-functional teams (designers, fabricators, and test engineers) early in the project.
Unlike ISO audits, IPC-9191 mandates product testing. The PDF specifies:
