我参加了今年JPCA展会，其依然是印制电路行业最大的盛会，由日本电子回路工业会JPCA主办，在东京有明展览中心举行。本年度的JPCA展会与JIEP 2017（第31届先进电子产品封装展）、JISSO PROTEC 2017（第19届Jisso工艺技术展）、2017大型电子产品展和2017 WIRE日本展同时在东京国际展览中心举办。日本的印制电路行业继续在艰难形势下谋求发展。与会者希望能发现日本线路板行业的最新行业趋势。
展会的规模与去年相当，但从产品线到材料供应商都有显著变化。对我来说参观者数量有增加，都非常期待看到新的技术趋势
设备厂商一如既往得占据了大量的展位，以展示他们的新产品。和去年一样YAMAHA、JUKI、Panasonic和Fuji Machine这些主要的装配机器厂商都有参展，并吸引了大多数参观者的目光，然而他们都没有展出重要的产品技术更新，宣传中只提及了一些经过改善的小细节，例如速度更快、生产效率更高、处理起来更方便、可靠性更强。较前几年相比，今年参展的钻孔机供应商数量要少一些。参展机器配备了新型机械钻孔系统，生产效率更高，并且还有针对微孔的激光钻孔机器。
挠性电路生产设备的供应商今年没有展出任何与光刻法或图形蚀刻有关的机器。相反，他们的特色产品线主要针对基本的工艺流程，例如冲孔和补强板粘结，从而提供更高的生产效率和更准确的卷对卷制程。
材料供应商今年也改变了他们的重心。层压板供应商今年没有介绍任何与覆铜层压板有关的产品。相反，他们带来了纳米粉和纳米油墨，希望能吸引新型应用的公司。
电路制造商带来的新技术主要针对日益发展的可穿戴设备、汽车电子产品和医疗设备市场。这些领域的关键词是可拉伸（弹性）和透明电子产品。
总体来说整个展会是成功的。我对于未来非常乐观——有不少新趋势。请期待下期的DKN通讯。
