请教一下高速板设计规则问题

哪位大侠能说说高速板一般的设计规则?比如信号线宽度，线间距，电源线宽度等?

有没有关于四层板，500MHz左右频率的设计规则?

智能手机CPU差不多500M,具体的线宽，间距要根据信号的要求而定。一般的再手机里面，4/4的线。

电源都不是很大，3G的大一点，用80MIL,CPU的电源用40MIL都足够，其他的最多也40MILS,问题不大。

The best MP4 Player will not be the same to everyone. Depending on the features you require, the best iPod Nano MP3 Player and ipod Nano MP4 Playerfor you will most likely be a different model then the best model for anyone else.

If you buy a ciphone c5 in a local store,you probably didn't think about the replaced accessories, but when you buy a imported Mini iphone from oversea,you better know how you can get the replaced accessories before your purchase. cheap ipod iphone the latest Hiphone clone from china, you probably know it or you probably own it.

Ciphone is an imported cell phone, normally you bought it on cheap hiphone online stores,the wholesale cheap iphoneitself always has 1 year warranty.

规则都是仿真整出来的。一套规则不一定适用别的板子，你拿到也没用。

4层板不存在太难的高速问题，也没有太高速的线给你设计，呵呵

是啊，通用的规则=没用的规则！

所以，一定要具体板子具体分析了。你可以先照着以前的板子做做，感觉哪里有问题了再拿上来问问，大家给你分析分析。
