Abstract:	台灣的印刷電路板產業產能、製程技術及專業的人才培育，在全球佔有舉足輕重之地位，然而印刷電路板製程的複雜特性，也使該行業必須更加重視職業安全衛生及災害預防。本研究探討印刷電路板製程容易引起重大災害的因子，利用某個案PCB製程高溫烘烤設備之直立式烤箱為例，運用失效模式與效應分析技術，經由專家小組的討論，將風險評估項目區分為危險物與有害物控制與防護、安全管理與維修保養、火災偵測與防護以及防火區劃等，分別分析失效模式及影響效應，並由風險優先係數的排序結果，認為高溫烘烤設備應就人員操作訓練、通風系統保養、易燃物儲存管理與緊急系統設置方面，提出應優先處理的預防因應對策，以做為業界之參考。The ever increasing popularity of mobile devices has had a great impact on the components suppliers. One of the key elements of the supply chain is the printed circuit board, PCB, manufacturers. Taiwan's PCB industry occupies a significant role globally because of its competitive edges in manufacturing technology, production capacity, and competent personnel. However, because of the complexities of the manufacturing processes and the consumption of highly flammable organic solvents, precautionary measures must be taken to prevent industrial accidents.Failure Mode and Effect Analysis, FMEA, is an effective tool in examining potential product or process failures, evaluating risk priorities, and determining effective prevention actions against identified problems. Major steps of FMEA analysis include identification of all possible modes of failure, identification of all possible causes of failure of each mode, determination of the likely effect and the likelihood of each failure, calculation of the risk factor for each cause of failure. A major advantage of FMEA is the use of detectability of a failure. Unlike simple risk matrix, FMEA uses the risk priority number, RPN, to rank risks. RPN is calculated by multiplying the ratings for consequence, likelihood of occurrence and detectability of an identified failure. If properly conducted, FMEA can provide effective prevention measures.This study uses FMEA to evaluate the risks of PCB process baking equipment and analyze all potential failure modes that may lead to fire hazards. The baking equipment fire safety program is divided into four elements, namely, hazardous substances controlling and protection, safety management and maintenance, fire detection and protection, and fire zoning. Results of the study provide significant improvements on PCB process baking equipment fire safety.
