常用PCB层叠参考NEW

1、常用PCB层叠说明：以下为常用的2-8层板公司最常用的层叠，在之前成熟层叠白基础上汇总，这些层叠都是我们公司经过批量验证OK的，请在设计时调用.因为这是是个通用模板，适合所有情况，整理在一起的时侯，可能有些微调.各种叠法很多，未包含的后续再补充.未包含的情况大家类似目前处理方法，找到之前曾设方t单板参考，基本都有.备注：1）改版还按之前的方式，新版设计，包括套用之前白模块布线，如果有更改，请修改下，方便后续重用.2）设计中如果没有用到模板中的阻抗线，请在模板中删除3）其他信号不得与有阻抗控制的信号线宽一致.有一致，其他信号线宽要稍作修改4）根据实际情况选择对应的层叠，特别是如果没有0.65MM

2、及其以下间距的BGA器件的，选用对应的.请务必对应好，方便后续套用.一.2层板层叠：LayerDescriptionThicknessL1COPPER1.1FR4XXXmi1L2|COPPERL8mi1阻抗控制表，一般不控制阻抗，无须填写1MPEDANCECONTROLSINGLEEMPEDklCELAYERwDTh|MIL)IMPEDANCELAYERWIDTHI/5PACE(MEL)IMPEDANCEDIFFIMPEDANCE备注:不同板厚的2层板根据板厚修改1,2层之间的介质厚度即可，其他不变二.4层板1.6mm:阻抗要求：2.0mm:LAYERWIDTH|MIL)IMPEDANCE1.
