| 摘要: | 在過去幾年中，Covid-19的疫情蔓延在這近年來持續的肆虐全球經濟，整個系統代工組裝廠面臨諸多的未知因素和挑戰。勞力密集的組裝廠，人是重要的因素，面對Covid-19變種擴散，導致招工不容易，加上人力成本的上升。除了保持客戶要求的品質外，代工製造商還必須引入流程改進和自動化，以彌補大流行引起的勞動力和材料短缺的影響。
本研究對象為國內電子組裝代工製造商，由於中美貿易和Covid-19雙重的衝擊下，面臨遷廠東南亞地區及其技術轉移緩慢和大陸人工勞動成本高漲且招工不易的情況，這些問題嚴重加劇了複雜且艱鉅。此外，品質水準是導致全球客戶信任和依賴的另一個主要因素。
本研究側重於EMS工廠的流程改進計劃。在其裝配過程中發現了包裝操作引起的質量問題，並提出了解決該問題的流程改進。首先，收集並分析相關數據，以查明包裝操作的異常情況。其次，研究了相對於當前自動化設備的包裝工藝方法和可行的替代方案。接下來，與製造廠執行系統（MES）研究監控生產過程的信息系統。最後，提出了一種過程變化，並對其可行性進行了分析。;In the past few years, the spread of the Covid-19 pandemic has continued to ravage the global economy. Electronic manufacturing service (EMS) factories throughout the world have faced with many uncertainties and challenges. Human resource is an important factor in these labor-intensive assembly plants. Due to the spreading of Covid-19, it is very difficult to recruit workers, and the cost of labor keeps raising. In order to avoid the risk of labor shortages, in addition to maintain the quality required by the customers, contracted manufacturers have to introduce process improvements and automation, to cover the impact of labor and materials shortages induced by the pandemic.
The target of this study is an EMS company. It has been facing problems of factory relocations to Southeast Asia, as a result of Sino-American trade war, as well as shunting ever increasing labor costs due to recruitment difficulties in mainland China. The Covid-19 pandemic has escalated the difficulties to its Chinese plants. In addition, level of quality is another major factor leading to the trust and reliance by the global customers.
This study focuses on the process improvement plan of the EMS factory. It identified a quality problem caused by the packaging operations in its assembly process, and proposed a process improvement to solve the problem. First of all, related data were collected and analyzed, to pinpoint the abnormality of the packaging operations. Secondly, the method of packaging process with respect to the current automated equipment and feasible alternatives were studied. Next, the information system monitoring the production process, in conjunction with the Manufactory Execution System (MES) were investigated. Finally, a process change, with its feasibility analyzed, is proposed. |
