新型印制电路板叠通孔设计及其制造方法

目前伴随现代电子产品向"轻、薄、小、多功能化"发展,电子器件的高集成化,互连技术从通孔插件(THT)向表面安装(SMT)和芯片安装(CMT)技术发展,加速了高密度(HDI)印制电路技术开发.高密度印制电路加工技术,成为当今印制电路行业的一个热门话题.目前PCB通孔结构有如下两种:VOI(Via On IVH)结构在层间通孔(IVH)上布设通孔(Via),即在IVH的引出线上布设VIA,呈螺旋形通孔(Sprial Via)结构,或直接在IVA上布设通孔.VOV(Viaon Via)结构直接在VIA上布设Via,呈现叠加形状.现通过研究开发新型PCB叠通孔互连方式HIH(Hole In Hole)结构,将更有利于高密度布线设计.论文涉及一种新的印制电路板叠孔布线设计方法,更确切说是印制板埋孔中增加过孔的设计及制造方法.

New stack of through-hole printed circuit board design and manufacturing methods

With modern electronic products to the currentlight,thin,small,multi-functionalof the development of highly integrated electronic devices,interconnect technology from the plug-hole(THT) to surface mount(SMT) and chip installed(CMT) technology development Accelerate the high-density(HDI) printed circuit technology development.High-density printed circuit processing technology becomes a hot topic.PCB throughhole structure currently has the following two:VOI(VIA on IVH) structure in the layer through-hole(IVH)...
