六西格玛方法在提升阻焊工序质量上的应用

Discussion on the method of copper plate evaluation on PCB

阻焊工序几乎为每款PCB的必经工序，其产品质量的优劣会严重影响产品交期、顾客满意程度，六西格玛方法是一套逻辑严谨标准规范的质量改进提升方法，通过使用该方法来研究阻焊工序的关键目标及其影响因素，并进行持续监督、改善、控制，阻焊工序每月可节约成本9万元／月，报废率在原基础上下降了60％。

Welding procedure is almost the required process of each PCB product. The quality of the product will seriously affect the product delivery and customer satisfaction. The Six Sigma method is a set of strict and standard quality improvement methods. The welding procedure can save 90 thousand yuan per month, and the rejection rate is reduced by 60% on the original basis through studying of the key targets and the influencing factors of the welding procedure, and carrying out continuous supervision, improvement and control.
