| Abstract | Failure Mode and Effect Analysis (FMEA), a DFM methodology of concurrent engineering, can be used to effectively increase process yield and reduce cycle time. FMEA is an engineering tool used to define, identify, and eliminate known and/or potential modes of failures in a product. In fact, FMEA is a methodology to evaluate the system, design, process, or service associated with delivery of a product to customers for possible ways in which failures can occur. System FMEA used to analyze systems and subsystems in the early concept and design stage and focuses on potential failure modes between the functions of the system caused by system deficiencies. Design FMEA studies the causes and effects of failures before a design is finalized. It provides the designer with a methodical way to examine the design. Process FMEA focuses on failure modes caused by process or assembly deficiencies. Service FMEA used to analyze services before they reach the customer and focuses on failure modes caused by system or process deficiencies. In essence, a product is examined for all the ways in which failures may occur. The failures are then evaluated for actions already taken or planned to minimize the effects and/or the probabilities of occurrence of the failures. Thus, FMEA identifies corrective actions required to prevent failures from reaching the customer, thereby assuring the highest durability, quality, and reliability possible in a product or service. This thesis presents an application of FMEA to an integrated-circuit assembly factory. As most product failures in this type of assembly occur due to design and process problems, the factory's current procedures in design and process FMEAs are analyzed for improvements. Implementation of the improved design and process FMEA procedures resulted in increased process yields and reduced defect rates. |
