Power Interfaces

Technical Library | 2019-10-07 10:56:06.0

Power interfaces are required when external power sources like solar panels, fuel cells, or batteries are used to generate power for electrical devices. There are two major power interfaces commonly used, direct current to direct current (DC/DC) converters and direct current to alternating current (DC/AC) inverters. While both interfaces are designed to convert from variable DC inputs, they output to different power standards and power levels that are used in different applications.

Thermal Interface Materials Testing

Technical Library | 2019-05-30 11:04:03.0

There exists a need to efficiently remove heat from power electronics within power systems to enhance performance. Thermal management is a critical function to that operation. Reducing the junction temperature of semiconductor power electronic devices enables them to operate at higher currents. Lowering operating temperatures reduces the thermal stress on electronic devices, which improves efficiency and reduces failures. To improve the heat removal process, the current heat transfer design of a power system has been analyzed and a variety of thermal interface materials (TIMs) and cold plate technologies have been evaluated. This paper will review some of these results.

Identifying Battery Load Qualification Test Parameters

Technical Library | 2019-05-30 11:02:07.0

In a previous Tech Tip (see Battery Selection for Electronic Systems), considerations were discussed for selecting an appropriate battery for an application. After selection, testing should be performed to confirm that the battery can provide the power required for the specific application. Some battery definitions should be understood when discussing power load qualification testing of batteries.

Technical Library | 2019-05-31 14:21:59.0

Microelectronics is the manufacture of systems built from extremely small electronic components. In today’s electronic world, devices must be portable, equipped with wireless technology and are driven by size, weight, power, and cost (SWaP-C). These system level drivers are crucial to all current and future electronic applications from personal computers and cellular telephones to military-fielded hardware, biomedical instrumentation, and space-flight hardware.

Fourier Transform Infrared Spectroscopy

Technical Library | 2019-07-05 09:33:05.0

Fourier Transform Infrared (FTIR) spectroscopy exists as one of the most powerful techniques for chemical identification and the most practical for “first step” analysis. Analytical instrumentation such as GC-MS and LC-MS are commonly used for identifying organic compounds. However, these techniques are costly and often require extensive set up time, method development, and sample alteration. Reliance upon FTIR as a robust and versatile tool can be based on its attributes of simplicity, speed, sensitivity, and affordability.

Advanced Packaging Technology

Technical Library | 2019-10-16 10:20:25.0

A major goal of the development of advanced packaging technology is to reduce the size, weight, and power consumption of electronics components using state-of-the-art commercial technologies. One of the novel concepts involves the use of all three spatial dimensions when designing and producing new systems. In the past, electronic structures tended to be two dimensional in nature. Generally speaking, individually packaged integrated circuit (IC) dies were interconnected on printed circuit boards. Techniques such as die and package stacking naturally contribute to a reduction of the spatial footprint of any given electronic system design.

Fiber Optic Cabling

Technical Library | 2019-11-13 13:53:50.0

Fiber optic harnesses appear simple, but they have been designed to maintain all of the critical areas of aligning two fibers and minimize the losses associated with a break in the transmission path. In order to understand how the connectors overcome alignment issues, we must first understand the issues. Fiber optic communications networks use specific wavelengths of light (or colors) to transmit information through a clear fiber at high speed. They use the property of internal reflection along the fiber’s axis to contain the light and keep the optical power high enough to be detected at the receiving end.

Identifying Flux Residues

Technical Library | 2019-05-23 10:42:00.0

Why identify flux residues? The primary purpose of flux is to reduce species of metal oxides from solderable surfaces, and to act as a mechanism for lifting and removing debris. If the assembly is not properly cleaned after manufacturing, flux may continue to reduce metals and may eventually corrode the assembly. When the assembly is powered, the metal ions may precipitate along electromagnetic field lines and form dendritic shorts. In addition, the presence of residue can alter the insulation properties of a board, affect the adhesion of the conformal coating, or interfere with the moving parts of the assembly. In radio frequency (RF) applications, flux may change the RF properties on the surface of the printed circuit board (PCB) such as the dielectric strength, surface resistance, and Q-resonance.
