摘要
裸光纤埋入式挠性光电电路(flexible electro-optical printed circuit board,FEOPCB)可有效解决电互联方式的传输瓶颈,还可实现不同子系统间的柔性互联,但要求埋入裸光纤与电路板层压工艺相兼容。首先对3种类型的裸光纤在层压工艺条件下的物理特性展开验证研究,经过光学显微镜观察分析,耐温裸光纤在高温、高压条件下无高温降解和破裂等缺陷。在聚酰亚胺基材上加工裸光纤定位结构,埋入耐温裸光纤并制作挠性光电电路,测试了其高速信号传输性能,在850 nm波长条件下通信速率可达10 Gbit/s,误码率小于10^(-16),试验结果表明耐温裸光纤可承受印制电路板加工过程的高温高压。
Transmission bottleneck of the electric interconnection can be effectively solved by flexible electro-optical printed circuit board(FEOPCB)with embedded optical fibers,which can realize the flexible interconnection between different subsystems.However,it is required that the embedded fibers should be compatible with the lamination process of the printed circuit board.Firstly,the physical properties of three types of bare fibers were verified under lamination process.Through the observation and analysis with optical microscopy,the result shows that the temperature resistant bare fibers had no high temperature degradation and cracking defects under high temperature and high pressure conditions.Location structures for the bare fibers were made in polyimide substrate,and FEOPCB was fabricated by embedding the temperature resistant bare fibers in the structures.Finally,the high-speed signal transmission performance was measured that a 10 Gbit/s communication rate with bit error rate of 10^(-16) can be reached at the wavelength of 850 nm.It indicates that temperature-resistant bare fibers have the bearing capacity under high temperature and high pressure during PCB processing.
