摘　　要：粘结片是印制电路板制造过程的中间步骤,其性能决定着印制电路板的可靠性.通过制备氰酸酯树脂(CE)/纳米二氧化硅(nano-Si O2)复合材料胶液,用该胶液对E-玻璃纤维实施浸润制造粘结片,探讨胶液的预聚时间对粘结片性能的影响.结果表明,预聚时间为80 min时,粘结片的含胶量和吸水率合理适宜,分别为42.04%和0.83%;可溶分含量相对偏高,为94.79%,应改进工艺条件进一步降低到理想状态.The glue of Cyanate ester resins （CE）/nano-SiO2 composites was prepared by using oven heating method, The in- fluences of prepolymeric time on the performances of bonding sheet were investigated through that bonding sheet which was made by glue infiltrating into E-glass cloth. The results show that the ideal state of prepolymeric time was 80min.The dissolved content of bonding sheet ,the water content of bonding sheet and the glue content of bonding sheet were 94.79%, 0.83% and 42.04%, respec- tively.
