Microelectronic packaging plays an important role in cryogenic engineering; in particular, a solder joint as interconnection, which offers a mechanical, thermal and electrical support, undergoes much larger and harsher thermal changes during its service compared with conventional customer electronic products. The impact of thermo-mechanical properties of such solder joints under cryogenic servi...

The effect of temperature cycling on the relative productions of aflatoxins B1 and G1 by Aspergillus parasiticus NRRL 2999 was studied. The cycling of temperature between 33 and 15 degrees C favored aflatoxin B1 accumulation, whereas cycling between 35 and 15 degrees C favored aflatoxin G1 production. Cultures subjected to temperature cycling between 33 and 25 degrees C at various time interval...

Room temperature vulcanized (RTV) silicone rubber is extensively used in power system due to its hydrophobicity and hydrophobicity transfer ability. Temperature has been proven to markedly affect the performance of silicone rubbers. This research investigated the degradation of RTV silicone rubber under temperature cycling treatment. Hydrophobicity and its transfer ability, hardness, functional...

Jean-Louis BIGOURDAN and James M. REILLY Image Permanence Institute Rochester Institute of Technology Rochester, New York, USA ABSTRACT The effect of changing environments on paper stability was studied using three types of paper (acid-processed 100% cotton, acid-processed groundwood, and buffered groundwood). The study was based upon three cycling situations. The effect of humidity cycling alo...

We use the GE High Density Interconnect(POL) Technology to create packages for 7x7mm and 3x3mm die in 90nm Radiation Hardened ASICs. We use HDI to “grow” the 7x7mm,3x3mm die to accommodate existing 1.27mm pitch LGA Packages. Next we create 16x16 and 10x10 BGAs with 0.8mm pitch for ultra small size, high acceleration, temperature cycling for

The emulsion explosive is one of the important industrial explosives. The structural stability of the water-in-oil (W/O) emulsion matrix of an emulsion explosive determines the reliability of its initiation, safety and detonation performance. It is known that the emulsifier is one of the most important factors affecting W/O structural stability. In this paper, several emulsifiers with the funct...

In this paper, we present a comparative study that focus on Supercapacitor (SC) thermal cycling and calendar ageing under constant voltage tests. The impacts of cycling temperature on SC performance and degradation rate are studied. Obtained results from thermal cycling ageing test are compared with those coming from simple calendar ageing test at constant voltage and constant temperature. The ...

Temperature cycling tests are standard industry practice for determining the thermomechanical fatigue life of solder joints. Industry-standard temperature pro¢les usually start from room temperature, then go to a high temperature, then to a cold temperature, and then back to room temperature. In addition, most of the time, the temperature pro¢le contains dwell times at the highest and lowest te...
