Guidelines on placing dedicated test pads for In-Circuit Testing (ICT) and flying probe tests.
If a machine were to rely solely on the board’s edges for alignment, the cumulative error could result in misplaced components. Fiducial markers solve this by providing a global or local coordinate system that is created during the same etching process as the copper traces. Because the fiducials and the pads are etched simultaneously, they share the same distortion characteristics. IPC-9191 establishes the rules for these markers, ensuring that the "eyes" of the machine can accurately translate the digital design file to the physical board.

The main objective of IPC-9191 is to outline a comprehensive SPC philosophy and supply actionable strategies to control variance across all manufacturing stages—stretching seamlessly from initial . 2. Core Concepts: The Core Philosophy of SPC
The primary purpose of IPC-9191 is to provide a foundational framework for applying statistical methods to monitor and control manufacturing processes. Rather than relying on end-of-line inspection to catch defects, IPC-9191 guides organizations to analyze process data in real-time. This allows engineers to detect and correct variations before they result in non-conforming products. The standard is aligned with the SPC principles outlined in the international document ISO/DIS 11462-1, "Guidelines for Implementation of Statistical Process Control (SPC) — Part 1: Elements of SPC". It is intended for a broad audience, including individuals in the electronics and other industries who are involved in the planning, implementation, and evaluation of an SPC system.
