Understanding the benefits of solar power

  Using solar energy would be a logical route for us to follow in an effort to alleviate the energy shortage. But we don’t. There are several good reasons why South Africans are reticent, amongst them being the cost of installation, lack of a clear understanding about what is available and, the fact that feeding […]

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 […]

Security cameras – it’s all in the technology

  Selecting the right camera for security applications is far more complicated than what one would think. It is not just selecting the right camera; lens technology and image processing technology are also factors to be considered, as well as whether quality pictures are possible in low light conditions; or whether the image processing technology […]

Ultra-low-power MCU modes – efficiencies and obstacles

  The market offers a large range of microcontrollers described as “ultra-low-power” (ULP). These MCUs aim to reduce and optimise the power consumption of all applications, so as to – in the case of battery-operated systems – extend the battery life. Several complying techologies exist: starting from an optimised energy-consuming active mode, to various sleep […]

EMI shielding effectiveness in conductively coated plastics

  Conductively coated plastics are becoming increasingly popular for EMI shielding. Vacuum metallising is a cost effective way to get fast turnaround in small quantities. Commonly, shapes can be complex, making it impossible to get absolutely uniform coatings. The article covers comparative shielding effectiveness (SE) tests on various configurations, primarily to assess the impact of […]

Super-broadband speeds – it’s all in the chip!

  The first deployment of the Infinera DTN-X platform across South Africa will deliver businesses with the simplicity, scalability, and efficiency expected from a fibre network – and it is all in the chip! Internet Solutions (IS), the first in South Africa to deploy the new technology, is now able to react to changing business […]
