两款PCB设计软件的埋容基本逻辑一致,需要为元件添加空腔属性,并在制造时对Prepreg板进行预切割,区别在于:Cadence需要预先设置层Embedded属性,对每个添加到该层的元件软件自动添加空腔;而AD在元器件封装中直接定义空腔。他们的操作步骤概述如下: BUG 使用版本19.1.7。 问题:在元件方向设置为Bottom时,Cavity方向始终向上。
Short circuit measurements and DESAT detection The designed measurement board is also used to test the short circuit behavior of the 1200 V CoolSiC Gen2p under very low-inductive and fast-switching applications. As the shunt resistor cannot withstand the high pulse energy in a short circuit event...
新创建的用于拼板的PCB如下,保存。 3,在新建的PCB上,点击 Place > Embedded Board Array/Panelize。如下图所示。 这个就是我们的拼版功能,点进去之后看到下图,在Embedded Board Array窗口中输出长和宽(这个参数一般比原板略大一点即可。视自己需求而定)。在 PCB Document 一栏选择你要拼的板PCB文件。然后在Colum...
eMMC(Embedded Multi Media Card)是嵌入式多媒体卡的简称,主要是针对只能手机和平板电脑特点二设计的。 它的实质是在NAND Flash的基础上增加了一个控制器,并预留了一个标准接口。 2、eMMC信号大体介绍 eMMC颗粒的PIN脚主要分为三组:电源引脚、控制信号引脚、数据信号引脚。 电源引脚 VCCQ电压:该电压由CPU的数据总线...
This is another challenging part of the PCB design process. This is where wires connect your components and create your completely unique PCB layout. An HDI PCB is a PCB which has a far higher wiring density than a conventional through hole PCB. Per IPC-6012 (1.4.1) this is defined as ...
Diff Embedded Coplanar Waveguide With Ground 内层差分共面阻抗,参考层为同一层GND/VCC以及邻近GND/VCC层 Diff offset coplanar waveguide 内层差分共面阻抗,参考层为同一层面GND/VCC,和邻近的两个层GND/VCC层 Coate Coplanar Strips 盖油后单线共面阻抗,,参考层与阻抗线 在同一层面,即阻抗线被周围 GND/VCC 包围,...
Embedded PCB components are passive devices fabricated within the PCB substrate. They reduce parasitic effects and enhance heat dissipation.
3、带状线(Strip-Line)或者埋式微带线(Embedded Micro-strip)的蛇形线引起的信号传输延时小于微带走线(Micro-strip)。理论上,带状线不会因为差模串扰影响传输速率。 4、高速以及对时序要求较为严格的信号线,尽量不要走蛇形线,尤其不能在小范围内蜿蜒走线。
