Reliability requirements for harsh environment electronic packages are increasing with the use of electronics in automotive underhood. The underhood includes various safety and critical functions such as automated locking systems, electronic fuel injection systems, engine control units, and anti-lock braking systems. Pad cratering manifests with initiation and propagation of micro-cracks beneath the BGA packages in the organic printed circuit boards. Major factors of these cracks formed with the combination of thermal cycling, shocks, vibrations, incorrect design or material selection, and manufacturing defects. In this investigation, the problem of pad cratering has been systematically approached by analyzing the bulk behavior of the resins using a tensile dogbone specimen and then moving forward with a bent specimen for the glass-resin interfaces. The first bulk study consists of 12 different resin formulations in which material property changes were studied under two and six reflow cycles. In the second part, a four-point bend interface specimen was used. The effect of reflow cycles was investigated by reporting perc-change in the Mode-I stress intensity factor and using this metric to rank the interfaces. In the end, an effort was made to create a predictive regression model with predictors being material properties of the samples such as elastic modulus, toughness, UTS, elongation of the resins, glass transition temperatures, and environmental conditions such as reflow cycles.

This paper deals with wireless networks, especially in the Internet of Things area. The aim is to design and implement a custom system for IoT in terms of hardware and software, using a suitable wireless transmission technology with the possibility of working in a mesh network topology, whose main advantages are the long communication range and low energy consumption. In order to develop the system that meets the specified requirements, universal, autonomously working, communication units are created. The user interface of the system allows to observe the status and evolution of the measured quantities, as well as to enter requests to the end stations. By deploying the system, it is possible to operate coverage-independent long-range bidirectional wireless communication. To ensure reliable data delivery, a packet delivery confirmation solution has been developed and backup technology is also included. The system is tested by deploying it on several sample tasks demonstrating its possible real use.

The IoT-based Smart Water Management system represents modern state-of-the-art technology which provides effective control of water resources for urban and rural areas. This system enables real-time assessment of water levels as well as stream flow and quality and usage pattern data by using advancedsensors and actuators and Internet of Things devices. The water delivery system benefits from precise wastage reduction through NodeMCU processing of data acquired from Ultrasonic sensor and flow sensor inputs that monitor water levels and leak detection. Motor pumps and valves receive data through the Driver Circuit. Cookies send the data to cloud infrastructure to display vital information through web-based dashboards for remote monitoring purposes. The system employs machine learning algorithms for detecting anomalies while also predicting future water needs to adjust the water distribution. The system uses Java's animation function to display water tank levels chaotically which provides both improved visual interface and instant system performance monitoring. The method saves 30% of water resources while reducing human labor expenses and ensures more sustainable water management and energy-efficient solutions. The proposed plan shows successful implementation for eco-conscious water resource management and environmental preservation within industrial spaces and agricultural zones and smart urban areas.
