| It gains great attention on the living environment as the global environment is getting worse & haze occurs frequently. As a starting point of environmental protection, the natural gas as a clean energy is increasing in gas market.The widespread use of natural gas drives the gas market development of peripheral products.T company is specializing in R&D, manufacture, sales and technical services on MEMS gas meter.MEMS gas meter received widespread att ention as it is superior to the traditional gas meter in smaller size/ damage, wider measurem ent range ratio and etc., and sales volume increased year by year.While sales volume grows,the meters returning were increasingThis article definite the purpose and significance of quality improvement.By the quality ma nagement theory, tools, and data analysis software Minitab study &research, also learning from the current quality situation of gas meter from T company. The improvement team use quality tools to analysis the effective factors in critical process, and found the root cause of the high repair rate was Sensor chip resistor.Thus, the main focus of this article is to analysis the cause and solves the resistor failure of sensor chip.Brainstorming and fishbone diagram was used during the preliminary analysis on sensor chip resistor failure.Matrix Data Analysis Chart & FMEA was applied in the phas e of cause confirming.And during the problem solving process we use the theory of GR&R and process statistical method to guide the analysis. Minitab software was used for data calculating, this is to save time and avoid human error.Through the quality improvement research on resistor failure of gas meter sensor chip, it provides reference for gas meter industry on quality improvement & other related quality issue. |
