- Abstract
- 국내에서 생산되는 PC CPU용 FCB의 LCA를 수행하였다 이 연구에서 도출된 결론은 다음과 같다 1. 목록분석 결과는 FCB 제조 전 원료 및 제조공정으로 분석하였고,목록 분석값의 대부분을 차지하는 것은 제조공정으로 FCB 제조에 따른 전력사용량 및 직접적인 유해물질 사용량이 많았기 때문이다 2. 제조 전 단계는 잉크공정 중 SR 7200가 모든 영향범주 5 ~ 20 % 사이에 분포되어 있으며, 이는 잉크 중 유기용제 및 중금속이 함유되어 높은 영향 평가를 가져왔다. 3. 기판 제조시 많은 양의 화학물질이 사용된다. 특히 전기동, 화학동, 금도금 공정 등은 유해물질의 다량으로 사용되어 산성화 등 모든 영역에 환경영향에 차지하는 비율이 상당이 높았다. 4. 특성화된 환경영향 결과 기판 제조공정 중 도금공정 특히 전기동은 생태독성(토양생태)에 99% 차지하고 있으며, 또한 영향범주에 14~ 99% 사이에 차지하고 있어 가장 심각한 환경영향 결과를 나타냈다.
- Alternative Abstract
- Life Cycle Assessment on Print Circuit Board Produced in S Electric Company was carried out. The system boundary encompasses raw material acquisition to the manufacturing of FCB(or cradle to gate). The product is FR 8 FCB used for a component of PC CPU. FR is a mixture of glass fiber and epoxy resin. Generally site specific data were applied However database were used when it is hard to get site specific data and Raw Material Suppliers Raw rating was assessed on the basis of the survey. Impact assessment was carried out consecutively as classification , characterization, normalization and weighting. Considered Impact categories are ARD, GW, OD, POC, Acid, Eut ET, HT. Life Cycle Assessment results of performing the manufacturing process FCB impact on all impact categories were Preparation of the SR 7200 process, the previous step, all the ink and impact categories are distributed between 5-20%, of the ink contain organic solvents and heavy metals brought to high-impact assessments, a large amount of chemical manufacturing steps to use, Especially electrolytic copper, chemical copper, gold plating process is used a lot of acidic toxic substances, etc. Impact on the environment in all areas, including a significant proportion of patients.
