无线通信 无线电干扰 Radio Susceptibility
 
Abstract: Engineers often wish that radio susceptibility (RS) or radio immunity could be cured with an antibiotic, a vaccine, or someform of cure-all. Unfortunately, solving the RS problem is not that easy. Indeed, the laws of physics apply. In this article we discusssources of RS. We als ...
机械电子 SMT生产线贴片机负荷均衡优化
摘要：采用表面组装技术（surface mountt echnology,SMT）进行印制板级电子电路组装是当代组装技术发展的主流。典型的SMT生产线是由高速机和多功能机串联而成，印制电路板（printed circuit board,PCB）上的元器件在贴片机之间的负荷均衡优化问题是SMT生产调度的关键问题。以使贴片时间与更换吸嘴时间之和最大的工作台生产 ...
可编程逻辑 PCB Design Considerations and Guidelines for 0.4mm and 0.5mm WLPs
Abstract: Using a wafer-level package (WLP) can reduce the overall size and cost of your solution.However when using a WLP IC, the printed circuit board (PCB) layout can become more complex and, ifnot carefully planned, result in an unreliable design. This article presents some PCB designconsidera ...
