Base On Six Sigma Of GIS(Foxconn) Ipad Product Quality Promotion Research

In recent years,apple's position as a global tablet leader has been weakening.In 2017,IDC released a report on the tablet market,showing that in terms of shipments,the iPad lineup had a market share of 50.4 percent in the third quarter of 2017,down 15.1 percent from 65.5 percent in the second quarter.Samsung,amazon and others are rapidly gaining market share.Huawei's tablet shipments have even registered positive year-on-year growth for four consecutive years.Faced with such an exciting competition,if apple wants to stand out from the competition,it must rely on quality to win.How to improve product quality,for apple has far-reaching significance.Based on the six sigma management theory,this paper introduces the development history,quality management system and the current situation of six sigma management of Foxconn GIS(shenzhen)co.,ltd.in detail through observation,experimental verification,literature research,induction and summary and the quality problems occurred in the company using six sigma improvement method for in-depth analysis,research,get the corresponding improvement countermeasures.In this paper,the problems occurred in the process of water-glue bonding in the production process of iPad products are analyzed,improved and implemented through five stages of six sigma DMAIC.First of all,in the six sigma definition stage,this paper determined that the specific problem point we want to improve is the yield improvement of the water-adhesive bonding process.Secondly,in the six sigma measurement phase,three major problems affecting the bonding foreign body were identified,namely the pipeline problem of water glue machine,the quality problem of dust free suit and the friction problem of tank chain,through the analysis of macroscopic process,measurement system,process capability and other methods.Thirdly,in the six sigma analysis and improvement stage,through a series of experimental analysis and data comparison,the improvement countermeasures that need to be introduced and the effectiveness of the improvement countermeasures are determined.Finally,in the six sigma control stage,the paper describes the tracking status of the improved results,the improved benefits and the control measures we introduced.As apple's contract Foxconn GIS(shenzhen)co.,LTD.,is also well-known domestic manufacturing enterprises,the quality problems in the process of manufacturing solution is very typical,and the current domestic research on the product quality of ascension is not a lot,so this paper research content is very representative.
