Link SPC performance to financial metrics, such as the "Cost of Quality". 2. The Statistical "Toolbox"
Without IPC-9191, operators might simply adjust a machine blindly. With the standard, every action is data-driven and auditable.
Selecting laminates capable of withstanding higher reflow temperatures required for lead-free solder.
The official is a copyrighted document and must be purchased through authorized distributors.
: Provides specific "how-to" guidance for applying SPC to Printed Board Assembly (PBA) and SMT processes.
Used for measurable physical parameters like copper plating thickness or solder joint heights (e.g., X̄cap X bar charts, or X̄cap X bar
: Data collection methods, control charting, measurement system analysis (Gage R&R), and corrective action systems.
Do not rely on memory. Input the spacing, trace, and clearance rules found in the IPC-9191 document directly into your Electronic Computer-Aided Design (ECAD) software’s Design Rule Checker (DRC).
IPC-9191 is uniquely valuable because it addresses specific electronics fabrication and assembly lines: Manufacturing Phase Specific Process Focal Points for SPC Monitoring
