DFQM-an approach for improving the quality of assembled products

摘要

In this paper we introduce first the concept of quality manufacturability (QM), and second a new methodology that focuses exclusively on evaluating a design from a quality perspective. We label this new approach as Design for Quality Manufacturability (or DFQM). The QM of a design is defined as the likelihood That defects will occur during its manufacture. Some designs are more likely than Others to have a lower production yield rate. The reason for this is that in any Production facility these is an inherent defect occurrence process.
