dc.description.abstractLED制造流程一般分为上游磊晶、中游晶粒、下游封装,而LED封装厂为了取得符合客户规格之色座标,因此需要进行试比例作业,以决定部分制程参数。本论文之研究,收集各系统资料统整成资讯,用来建置LED封装厂的核心技术之“试比例回馈系统”平台,工程师除了方便掌握各项资讯外,并运用这些历史资料预先模拟适当的制程处方,不仅可以加速产出也可以提升产出周期,省去不少人力来计算制程处方,也让工程师和作业员之间沟通无障碍,避免资讯不及时或资讯传递有误差,并可减少作业员因为抄写错误参数而导致产品良率降低。
整体研究成果包含“物料系统”管理供应商、萤光粉和封装胶等资讯;“点胶系统”提供试比例申请、生产资讯表、点胶资讯、产出分布、放量等功能;“回馈系统”依据产品属性,并参考历史资料的各试比例资料,运用线性回归原理或Weight %调整模组,进行Weight %的模拟回馈计算后,产生分布图、线性方程式和各项数据指标回馈给工程师,让工程师能更迅速做出适当的决定,而这些统整的技术知识,包含制程重要参数、指标、产出分布图等资讯,也有助于训练新进工程师之辅助,让新进者能快速掌握试比例流程和方法。
由实验结果显示,试比例次数和产品周期皆有降低的趋势,以及CIE目标差距缩小,表示Weight %预估准确,整体产出分布也很集中。过去工程师使用纸本或试算表的平均试比例次数约为6.53次,与系统上线后平均试比例次数为4.27次,降幅约为34.6%。
未来,期望能藉由本论文建置之“试比例回馈系统”,由系统定期训练Weight %调整模组,并排除异常点以达到自动回馈的机制,更进一步扩充到双粉试比例回馈系统,以便让工厂运作更为自动有效率。

dc.description.abstractLight Emitting Diode (LED) manufacturing is generally divided into upstream Epitaxy, middle Chip, downstream Package. In the LED Package factory, it’s necessary to obtain the CIE coordinates in order to meet customer specifications. Therefore the factory does the try-run operations before mass-production which is the core technology of the LED Package. In this thesis, we created the Try-Run Feedback System to integrate information from various systems and to provide useful information for this operation. With this system, engineers are easy to master all kinds of information and use historical data to simulate the process recipe. Many advantages can be achieved such as speeding up the output, enhancing the output cycle by elimination the need for a lot of manpower to calculate the prescription of the process, providing better communication between the engineers and the operators, providing the precise and on-time information and increasing product yield by preventing from mistyping parameters.
The overall system architecture consists of material management system, dispensing systems, feedback system, etc. The material management system is used to manage the information of the supplier, phosphor and glue. The dispensing system is used to manage the try-run requisition, run card of the process flow, dispensing process parameters, product color distribution and release control for mass-production, etc. Based on product attributes, and historical data of each try-run data, the feedback system uses the principle of linear regression or Weight% adjustment module to calculate the weight% of the phosphor to glue, generating the charts of product color distribution, linear equations and many useful indicators for engineers which help engineers to make appropriate decisions quickly. Thus the junior engineers will familiar with the processes of the try-run operations quickly with the systematize knowledge which including the important parameters of the process, indicators, color distribution and other information.
From the experimental results, the times and cycle time of try-run are decreased, the gap between the CIE target and the result are also reduced, which reveals the precisely Weight% and the concentrated color distribution. The try-run times was enhanced for 34.6% from 6.53 to 4.27 times.
In the future, the weight% module will be adjusted automatically by the Try-Run Feedback System in order to exclude the outliers and to achieve automatic feedback mechanism. The other application is to support double phosphors in Try-Run Feedback System, to improve manufacturing efficiency.
