Thermal, mechanical, dielectric properties and moisture absorption performance of CCLs were improved with the increase of cyanate content.
覆铜板的热学、力学、介电等性能随着随氰酸酯含量的增加均得到改善。
Copper clad laminates ( CCLs) with high performance based on modified polytetrafluoroethylene ( PTFE) were prepared by using blended tetrafluoroethylene and hexafluoropopylene ( FEP) as the modification resin.
利用聚全氟乙丙烯(FEP)共混改性聚四氟乙烯(PTFE),制备了高性能聚四氟乙烯覆铜板。
The absorbed water can not be completely desorbed from the resin, so the absorbed water will increase the dielectric constant and loss, however, the enlarged values still meet the requirement of high performance matrices for high performance CCLs.
吸湿水不能完全从树脂中脱出,所以吸湿后树脂的介电常数和介电损耗大于未吸湿树脂的相应值,但是仍然符合高频覆铜板用树脂基体对介电性能的要求。
