Testing the limits of IEEE 802.11ac wireless networking standard

  The evolving wide-bandwidth IEEE 802.11ac communications standard brings new benefits to users but new challenges to those tasked with testing products based on this standard. As the IEEE 802.11ac wireless standard evolves, it continues to breed new challenges for those tasked with testing and measuring these wireless systems. As products based on the IEEE […]

Thermal stress on capacitors: failure prevention

  Failure of capacitors affects the other components in the circuit and causes secondary failures in many cases. This article discusses the failure modes and mechanisms in capacitors of various types which are typically used in electronic systems and methods to prevent capacitor failures due to thermal stress. Various types of passive components are used […]

Implementing a high-yield alternative assembly and reflow technology process

In a White Paper entitled “Comprehensive guidelines for the implementation of the AART process”  the authors* examine the entire alternative assembly and reflow technology (AART) process. It is designed to provide a process engineer with some of the knowledge necessary to implement a high-yield AART process. The AART principles illustrated in this paper can be […]
