PCB、IC封装：设计与仿真分析: 针对电气工程师的热管理基础——第一篇

Sigrity

作者：Lawrence Der 在过去，机械工程师全权负责产品的热力设计，包括产品的机械外壳和其它物理方面的设计；然而现在，热力设计问题却是要电气工程师来共同承担。随着嵌入式微控制器、固件和传感器等的出现，电气工程师在产品的热力管理中起到的作用越来越大。而作为电气工程师，您是否体验过设计的产品超过了温度规范，却不知道要如何解决或减轻这个问题。特别是随着产品设计的功率密度越来越高，元器件每单位体积消耗的功率也越来越大，导致我们的产品越来越容易发热。在针对电气工程师的热管理基础系列文章的第一篇中...

PCB、IC封装：设计与仿真分析: 升级到Allegro17.2-2016的10大理由之10：易于使用的改进

TeamAllegro

我所认识的大多数PCB设计工程师跟我有同样的习惯… 我们有最喜欢的颜色、板层名称、定制的键盘，我们最大的目标是看到一天之内完成了多少条网络布线。我们很少有改变这些使用习惯，—但当我们改变时，要么是因为换了设计人员，要么是由于这些证明是好的流程却不再满足工作要求，我们不得不改变。您能联想到吗？你们之中有幸参加之前Cadence用户大会CDNLive会议的，可能会记得，作为客户，我通常会演讲“Allegro技术小贴士-您知道吗？”平心而论，我被邀...
