中文摘要
印刷電路板(PCB)是所有電子產品不可或缺的基礎零件，也稱之為「電子工業之母」，其製作上可歸類分為乾式製程與濕式製程，其中濕製程過程中需有多種化學反應，反應完成後需將多餘殘留的化學物質沖洗潔淨，以防各種品質異常現象發生，清洗過程中產生之清洗水部份供給中水回用處理系統產生中水再利用,其他經由廢水處理系統來排放。經實地訪談印刷電路板產業用水管理方式，得知目前PCB產業用水上仍無法預知精確計算當日耗水的合理水量，僅能由過去經驗推算且無從統計各製程總用水量與排放量，再者也無法及時修正在管理上對於耗水的使用對策。因此，本研究透過動態資訊流的計算管理得知量並與現場實際用水量來做差異比較做到及時監控、即時修正各製程的異常耗水，以期達到在線監控與有效之節水減排。
本研究將耗水大數據週期研究流程分為三期，包括資料模式建立期、資料驗證期、與實際監控期。分析內容包含取水成本計算、標準用量計算，並透過資訊監控進行製程數據搜集，整體資訊監控採用電子水錶並與系統監控台進行鏈結，以達成訊息的即時蒐集與傳遞，並於偵測異常狀況時發送訊息至水錶管理者。
本研究透過取水成本分析發現投資中水回收所耗的花費和環保效益，遠不及實施監控水系統來得有效益，而透過本研究之資訊監控，設定不同警報標準，並比較標準耗水與實際耗水，再於異常狀況下進行調整改善，可使耗水狀況改善並趨於穩定，同時確認監控警報範圍與可行性。本研究最後進行節水效益分析，發現於節水減排之同時，可潛在增加工廠產量才是最大利益。整體來說，建構PCB工廠之節水減排資訊監控系統，除可有效進行工廠之水資源善用，對於相關業務之管理人員亦提供良好之系統，確認是否發生異常耗水，以即時進行改善。節省下來的用水量，進而轉成額外產出同等比例的產能，創造永續的成本價值；換言之，維持相同的廢水處理量進而增加製造產能，使設備充分利用擴大企業經濟規模對營運將能產生最大之效益。

Abstract
PCB is the fundamental part of all electronic devices, which granted it the name of “the Mother of Electronic Industry.” Main methods of manufacturing PCB are wet and dry process, for which wet process generates multiple chemical reactions. When reactions terminate, the extra chemical matters must be rinsed off to prevent different types of quality abnormity. The used the water during the process will be recycled by a system while the rest will be processed into sewage water system. Through actual interview with PCB industry, it is understood that PCB industry can neither forecast nor perform accurate calculation of appropriate water usage per day. It could only be estimated through past experiences. The total water usage and emission cannot be statistically recorded. Additionally, there are no immediate corrections on water usage management and strategy. Through active data and calculation management, this research can credibly inform accurate water usage and using the difference between actual and calculated water usage to monitor and correct abnormal water usage of each process instantly for live-stream surveillance and effective water saving.
This research divides water consumption big data into three periods, including data model establishment, data verification, and actual surveillance. Analytical contents include calculation of water intake costs, standard usage calculation, and process data collection through information control. The general data control adapt electronic water meter and connects it with system control center to achieve immediate message collection and delivery; it sends alert messages to water meter manager when irregular pattern is detected.
Through water intake cost analysis, this research discovers that the return on investments of reclaimed water and the environmental advantages are far less effective than implementing water control system. By enacting different alarming standards and comparing standard and actual water usage, adjustments are made possible; making adjustments under irregular conditions can allow water usage circumstances to improve and stabilize. At the same time, it confirms monitoring warning ranges and feasibilities. In the final stage of the research, water saving benefit is analyzed. It discovers that while water saving occurs, the potential of increasing capacity is the ultimate advantage. Overall, forming of water saving data monitoring system of a PCB establishment can not only effectively use water resources, but also provide outstanding system for related managers. It confirms the occurrence of abnormal water consumption to achieve imminent improvement. The value of the water saved can further produce additional productivity. This creates infinite cost value.
