一、IC EMC集成电路电磁兼容测试是什么?
过去,EMC兼容性一直是电子产品模块级或系统级问题。
现在,电子设备制造商开始要求半导体制造商指定集成电路(IC)的辐射和抗扰度水平。一些半导体公司通过开发专有测试方法做出了响应,而另一些公司则与设备制造商和国际电工委员会(IEC)合作,制定了一些通用型的IC EMC测试和测量的标准方法。
二、IC EMC问题来源:
除了布线和结构设计外,设备中所使用的集成电路IC的特性也决定了它的EMC特性。IC对快速脉冲的敏感性随其结构尺寸、工作电压、工作点的较少而显著增加。当前的集成电路和微控制器开发领域趋近于结构小于100nm水平,甚至电脑芯片组已经达到7nm。并且伴随更高的开关率致使IC的EMC-EMS免疫性相较早期产品下降近90%。这种趋势也将最终反映在设备级别的EMC特性上。所以对于相同的功能的IC,良好的EMC特性能够提高IC制造商的竞争优势。
三、如何提高IC的EMC兼容性竞争力?
3.1、提高IC集成电路的电磁兼容性能应该首先从符合IEC标准开始:
在没有相应能力和资质规划符合自己产品的EMC标准时,IC制造商应该首先遵循国际电工委员会IEC的测试标准。然后在利用IEC标准开发符合自己产品的企业标准。
现在,IEC技术委员会TC47(半导体器件)正在领导 IEC 的工作。委员会将 EMC 测量标准的工作分配给其小组委员会 (SC) 47A+集成电路。TC 47/SC 47A 创建了工作组 (WG) 9,以准备测试和测量方法。WG9 的工作计划与其他行业和国家标准机构合作,如美国汽车工程师协会 (SAE) 和德国的埃德列克特罗尼克 Elektronik信息技术公司(VDE)。和产品及设备级别的EMC标准一样,IC-EMC也包括两种测试,射频EMI和射频抗扰度EMS的标准系列。
