The growth of Electronic products becomes more complex due to a major requirement of high reliability, high speed and low cost. In today¿s world, reliability becomes a great need of any electronic equipment for active as well as passive components such as a temperature sensor. Failure prediction is the major constraints to predict the remaining useful life of the component in order to anticipate the costly failures or system unavailability. In the modern competitive market, low cost and high performance are the key factors to attract the customers towards their products. Growing system complexity demands robust control to reduce system control and to reduce the successive failures. Reliability prediction of passive components especially temperature sensor is of great concern as these are required in almost every system. As these components are mounted on a board to form a complete system, the probability of damage is increased, as the different components have different characteristics and different operating conditions. So artificial intelligence techniques are used which adopt knowledge of failure mechanism of an individual part of the system and check the health condition of it.

From daily life applications to military applications and from toys to satellites, the use of electronic components is in extensive. Due to rapid evolution of electronics device technology towards low cost and high performance, the electronics products become more complex, higher in density and speed, and lighter for easy portability. Reliability prediction of the electronic components used in industrial safety systems requires high accuracy and compatibility with the working environment. The user can replace faulty component with the accurate one, and system will be saved from complete shutdown. Using low-cost materials, carbon, and potash alum, a new solid composite electrolyte system was fabricated and characterized using various techniques. An Arrhenius behavior was reported when the temperature dependence of conductivity was analyzed. The synthesized solid composite electrolyte exhibited excellent humidity sensing behavior. An expert system was modeled using artificial intelligence techniques and failure of the sensor was predicted using artificial neural networks (ANN), fuzzy logic (FIS) an adaptive neuro-fuzzy inference system (ANFIS).

The trend in design and manufacturing of very large-scale integrated (VLSI) circuits is towards smaller devices on increasing wafer dimensions. VLSI is the inter-disciplinary science of the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip.
