【摘要】 主要介绍制备微波高频PCB覆铜板时,PTFE树脂中FEP乳液体积浓度对浸渍玻纤布树脂含量的影响,以及对制作的pp(Pre-pregnant)介电常数(Dk)和介电损耗(Df)的影响。试验显示,随着树脂中FEP乳液含量的增加,浸渍玻纤布树脂百分比降低,而Dk和Df值升高,用pp所制作PCB覆铜板的铜箔剥离强度随着FEP乳液含量的升高而增大。更多还原

【Abstract】 This article revealed that the effect on glue content, Dkand Dfdepending volume concentration of FEP emulsion in PTFE resin on of impregnated fiberglass cloth, when making microwave high frequency copper clad laminate. With the increase of the concentration of FEP emulsion in the resin, resin content in impregnated fiberglass cloth reduced while Dkand Dfincreased. In addition, peeling strength of copper foil of copper clad laminate made of impregnated fiberglass cloth increased with FEP content increase.更多还原
