This part of IEC 61193 defines methods of registration and analysis of defects on soldered printed board assemblies. Methods are described to allow effective comparison of perform-ance between products, processes and production locations and can serve as a basis for general quality improvement.
The standard specifies defect data collection in two categories.
Category 1 ppm data: this category provides data for registration purposes intended to enable overall performance comparison of assembly operations.
Category 2 ppm data: this category provides data intended for individual subprocess assessment, analysis and control purposes.
