摘要
研究了刚挠结合印制板中挠性区埋入尺寸dE、刚挠互连盲孔距刚挠结合边缘尺寸dH、及该类印制板的挠曲次数Y等之间的关系,获得的拟合方程式为:Y=-34.2+22.7dE+16.3dH。实验结果表明,dE=2.0cm,dH=1.8cm是满足6层刚挠结合印制板弯折4000次数挠曲性要求的最小临界参数。
The paper studied the R-FPCB embedded dimension dE, the dimension of blind hole to the R-flex edge d., and the number of deflection Y in R-FPCB. The fitted equation i s:Y =-34.2+22.7dE +16.3dH. The experimental results showed that the minimum critical parameters that meet the deflection request of bending 4000 times were dE=2.0cm, dH = 1.8cm in 6 layer R-FPCB.
