As manufacturing moves toward Industry 4.0, the remains relevant—but with a modern twist. Traditional SPC involved manual plotting on paper charts. Today, automated SPC software (e.g., InfinityQS, Siemens Opcenter) ingests real-time data from pick-and-place machines, reflow ovens, and test systems.

IPC-9191 was developed by the IPC’s Statistical Process Control (SPC) Task Group to address a critical gap: many manufacturers collected SPC data but failed to act on it effectively. The standard provides a step-by-step methodology for:

To identify the "vital few" root causes that account for the vast majority of surface-mount technology (SMT) or fabrication defects. ipc9191 pdf

A reliable source for obtaining industrial standards.

Before purchasing, check if your company already has an IPC corporate subscription. Many large EMS (Electronics Manufacturing Services) providers include IPC-9191 in their internal document portals.

Control charts act as the operational heartbeat of IPC-9191. They graph process performance relative to time, calculating statistical upper and lower limits to verify process stability.

: Promotes the use of standard SPC tools like Control Charts (I-MR, p-chart, c-chart), Histograms, and Pareto Charts to manage process drift. Implementation & Related Standards Traditional SPC involved manual plotting on paper charts

: Driving long-term variability reduction to lower internal and external failure costs. System Elements

While IPC-9191 is the general foundation, companion standards provide industry-specific applications: : SPC for base materials (laminates/prepreg). IPC-9193 : SPC for printed board fabrication. IPC-9194 : SPC for printed board assembly (PBA).

By identifying and controlling process parameters (

Adhering to recognized standards like IPC-9191 demonstrates a commitment to quality, often a requirement from OEM customers.
