求微带线FR4基片具体参数

这个很难说
Er 4左右吧
厚度10-60mil不等

介电常数不稳定，4~5之间都有可能，因此不宜做高频板设计，厚度0.5~3mm好像都有。

厚度可能有很多种可以选的
我个人用过的有：0.2mm，0.5mm，0.8mm，1mm，1.5mm，2mm，3mm这些型号
主要使用频率要低于3GHz
介电常数一般分布在4.3-4.7之间，理论上可以认为是4.4

其实你用4.3和4.7算出来的带线宽度差不多，做出来东西也差不多，加工还有误差嘛。

老外的解释，我直接拿来了，希望有用
FR-4, an abbreviation for Flame Retardant 4, is a type of material used for making a printed circuit board (PCB). It describes the board substrate, with no copper layer. FR-4 meets the requirements of Underwriters Laboratories UL94-V0. The FR-4 used in PCBs is typically UV stabilized with a tetrafunctional epoxy resin system. It is typically a transparent yellowish color - the green, red and sometimes blue color of a finished board comes from the topcoat. FR-4 manufactured strictly as an insulator (without copper cladding) is typically a difunctional epoxy resin system and a greenish color. FR-4 is similar to an older material called G-10. G-10 lacked FR-4's self-extinguishing flammability-characteristics. FR-4 has widely replaced G-10 in most applications. Some military applications where destruction of the circuit board is a desirable trait will still utilize G-10.

谢谢各位的回复 哈
谢谢各位的回复 哈
谢谢
但,有个问题:
您们怎么搜到有关FR4的使用手册的呢?
我搜了些资料,但总是一些零散的东西
