六西格玛在提高TO-252胶厚合格率中的应用

The Applications of Six Sigma in Improving Qualified Rate for TO-252 Epoxy

该文对某型号TO-252的胶厚合格率进行了分析。针对目前该型号产品的胶厚合格率偏低问题导入六西格玛质量管理模式对生产流程中的各项要素、参数和指标进行了研究,通过分析定义了关键问题,通过MSA对装片完成后显微镜聚焦测量法进行了改善,保证了测量系统的精确性和准确性。通过对流程中的变量因子的重要性验证并提出相应的改善方法,最终使该型号TO-252封装的胶厚合格率达成预期目标。

In this paper,the qualified rate of rubber thickness of a model TO-252 is analyzed.Aiming at the problem of low qualified rate of rubber thickness of this type of product at present,the Six Sigma quality management mode is introduced to study the factors,parameters and indicators in the production process.The key problems are defined and analyzed.The microscopic focusing measurement method after filling is improved by MSA,which ensures the accuracy of the measurement system.Sex and accuracy.By verifying the importance of variables in the process and putting forward corresponding improvement methods,the rubber thickness qualified rate of the TO-252 package can reach the expected goal.
