新华 5月8日电 据美国科技博客Gizmodo 道，三家英国公司在政府的支持下开发了一种新型的集成电路版，其材质有90%可以回收，而且回收的方法仅仅是把它们泡在热水里，然后用硬纸片刮一刮。
这一产品的出现得益于一种新型可导电粘合剂。电路板制造商只需要把元件用这种粘合剂粘在可回收的热成型基板上就可以。把电路板泡在接近沸腾的热水中，粘合剂就会溶化，元件也就可以被刮下来重新使用。
“使用废旧电器的最大问题是造成的垃圾越来越多，”开发这种技术的克里斯·亨特说。“现有的电路板加工技术基于环氧玻璃和焊接技术，很不易于回收利用。”但是他说，“但这肯定不是用于所有设备的解决方案。”
确实，还需要很多时间才能让这项技术投入实际大规模生产。但是以前回收罐头的时候他们也这么说过。

You Can Recycle These New Circuit Boards by Dunking Them in Hot Water
It almost seems too easy. With government funding, a trio of British companies recently developed a new way to build circuit boards that makes them 90-percent recyclable. In fact, all you have to do to recycle them is dunk them in hot water and scrape off the circuits with a business card.
The innovation was made possible thanks to a new conductive adhesive system. Circuit board manufacturers simply attach the components to a recyclable thermoplastic substrate using this special adhesive. Dipping the whole assembly into almost-boiling water causes the adhesive to soften enough that the components can be scraped off and reused.
“What happens to end of life electronics is one of the fastest growing waste streams,” Chris Hunt, who helped develop the new technology, told The Guardian. “Existing electronic circuit assemblies are based on reinforced epoxy glass systems and solder… that isn’t easily recyclable.” However, he adds, “This is definitely not a solution for all types of electronic technologies.”
Indeed, it’ll take some time before the process is streamlined enough to make it into mass produced electronics. But, hey, they used to say that about recycling cans, too.
