失效模式及其影響分析培訓教材內容提要：
What is a FMEA?
A structured, disciplined process to systematically and comprehensively, identify and document potential problems and weaknesses in a design or process so that design changes can be made or other corrective actions taken to prevent actual occurrence of failure
Objective of FMEA
Failure Mode & Effect Analysis (FMEA) is used to improve
product reliability (considering usage, environment, lifetime etc.)
quality of (purchased) parts (incl. ‘hidden’ functions of a part)
reproducibility of the product (reduction of fall off & repairs in assembly)
reproducibility of the production process (handling, transport etc.)
Focus on technical problems
Link with Maturity Grid and Risk Management!
Use of FMEA
A. Reliability Engineering
- Reliability improvements.
B. Producibility Analysis
- Less repairs and scrap during manufacturing.
- Improvement of the Zero- Hour Quality.
C. Production Process Analysis
- Less repairs and scrap.
- Determination of process control points.
- Process release.
A and B during development phase. C during work preparation phase.
