Finally - an end to the confusion when calculating defect opportunities for benchmarking! For customers and manufacturers, it seems like every company has a unique way of calculating defects and then reporting on quality. In a complex electronics assembly operation, is it best to calculate using the number of components? The number of leads? What about solder joints? How can companies calculate...
