| Abstract | An investigation of the way in which voltage applied to components during an accelerated humidity test influence the test lifetime of these components is discussed. A humidity test in which plastic-encapsulated CMOS circuits were aged in an environment of 130 degrees C and 85% RH was performed. The components were divided into groups with different voltage conditions. The applied voltage was either pure supply voltage, which does not give rise to any significant power dissipation, or a voltage condition that causes a power dissipation of 30 mW. The first of these voltage conditions is the most common way to bias CMOS components being tested in a pressure cooker, whereas the second one is similar to real operating conditions. The voltage condition of the components in the different groups were altered in time between the two conditions in a pattern specific for each group, so that an intermittent operating mode was obtained. The humidity test indicated that the test lifetime differed among the groups. A group that was operated intermittently showed the highest number of failed components.< |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
