| Abstract | Flexible printed circuit boards (fPCBs) have an important role in electronic product miniaturization due to their reduced thickness and ability to bend and adapt to various shapes. As with any new technology reliability should be assessed to guarantee quality of products that benefit from the additional features. Typical causes of cracking failure in electronic devices are related to mechanical stress, moisture, and heat from transportation and field use. Typically manufacturers carry out tests to evaluate the reliability of electronic components regarding these types of loads. Common tools used for this evaluation in early stages of design are finite element analysis and experimental laboratory tests. In this present work simulation models were proposed in order to develop tools for early stages of design. Thermomechanical tests were performed experimentally to assess reliability of parts and also provide information to evaluate the simulation models. The objective of this work is to develop simulation models for flexible printed circuit boards (fPCB) flex-rigid interfaces and to perform experimental tests in laboratory in order to evaluate the cracking phenomena when this device is submitted to thermal cycling. |

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.
