金屬表面處理業中的電鍍加工作業，使工件提升金屬外觀細緻度、延長產品使用年限亦或增強金屬導電性等，是兼具美觀及實用性的傳統工法，亦是工業製程中不可或缺的加工產業之一。
電鍍產品之良率主要受到設備、作業及保存環境所影響，尤以空氣品質影響最為劇烈。作業環境之空氣濕度、酸鹼值、揮發性有機污染物及懸浮微粒PM10與PM2.5，除了影響金屬氧化及受腐蝕速度，若懸浮微粒M10與PM2.5落入電鍍溶液中，可能與金屬離子於陰極一併沉積，導致產品表面受雜質影響降低鍍膜精緻度，致使產品不良率提高。
為了解電鍍作業產線空氣品質對產品良率之影響，本研究採用「設計科學研究法」，以研究生自營之「縺騏股份有限公司大園廠」電鍍產線為研究對象。透過設計及建置新式產線，運用具活性碳初級濾網及HEPA高效濾網之空氣潔淨設備，與具物聯網即時監測及控制設備之潔淨室電鍍產線，針對空氣污染因子進行嚴格控管，並紀錄及分析實際生產情形數據，比較舊式與新式產線產品良率變化。
本研究之結果顯示：新式產線作業環境之PM2.5濃度平均約為8.082μg/m3，相較舊式產線作業環境之17.227μg/m3平均降低約53%。新式產線TVOC濃度平均約為147.687ppb，相較舊式產線之278.935ppb降低約40%。舊式產線產品不良率3.33%，新式產線產品不良率則顯著降至約0.65%，整體產品良率提高至99.35%，顯示空氣品質可顯著影響電鍍產品之良率。

Electroplating is a kind of metal surface treatment. It may increase the product's lifespan, promote metal conductivity, and improve the delicateness of the metal look. It is a time-honored technique that is both beautiful and useful. It also serves as a vital processing sector for products produced industrially.
The equipment, operation, and storage conditions, particularly the air quality, have an impact on the yield rate of electroplating goods. Metal oxidation and corrosion rates are influenced by the working environment's air humidity, pH value, volatile organic compounds (VOC), and particulate matter (PM10, PM2.5). The particles may be deposited with metal ions at the cathode if they fall into the electroplating solution. This leads to a buildup of contaminants on the product's surface, a reduction in membrane delicacy, and an increase in the product defect rate.
In this study, "Design-based Research" was employed to comprehend how the air quality affected the product yield rate. The study was conducted at the "Lian Chyi Co., Ltd. Tayuan Plant," which is owned by graduate students. A new product line was created and constructed using the cleanroom electroplate product line's carbon primary filter, high-efficiency particulate air (HEPA) filter, and real-time network monitoring and control technology. The elements that contribute to air pollution were rigorously monitored, and statistics on the actual production situation were collected and examined. Both the old and new product lines' yield rates were compared.
The average PM2.5 concentration in the new working environment was 8.082 g/m3, compared to 17.227 g/m3 in the previous product line, representing a 53% decrease. With a 40% decrease rate, the overall VOS concentration was 147,687ppb in the new design compared to 278,935ppb in the previous product line. With a high yield rate of 99.35%, the product defect rate was 3.33% for the old product line and 0.65% for the new product line. This outcome demonstrated how air quality may have a considerable impact on the rate of electroplating product yield.
