应用范围：打印机打印头与主板之间的连接，绘图仪、扫描仪、复印机、 音响、液晶电器、传真机、各种影碟机等产品的信号传输及板板连接。 端子线又称Flexible Flat Cable(FFC)可以任意选择导线数目及间距，使联线更方便，大大减少电子产品的体积，减少生产成本，提高生产效率，最适合于移动部件与主板之间、PCB板对PCB板之间、小型化电器设备中作数据传输线缆之用。普通的规格有0.5mm、0.8mm、1.0mm、1.25mm、1.27mm、1.5mm、2.0mm、2.54mm等各种间距柔性电缆线
“二代证”是中国第二代居民身份证的简称。中国从1985年实行居民身份证制度，由于该证防伪、安全使用性能较差，国务院于2001年6月批准研制和换发“二代证”。 “二代证”为非接触智能IC卡型，长85.6mm，宽54mm，视读和机读均可
