A test program was developed to evaluate the effectiveness of vacuum reflow processing on solder joint voiding and subsequent thermal cycling performance. Area array package test vehicles were assembled using conventional reflow processing and a solder paste that generated substantial void content in the solder joints. Half of the population of test vehicles then were re-processed (reflowed) using vacuum reflow. Transmission x-ray inspection showed a significant reduction in solder voiding after vacuum processing. The solder attachment reliability of the conventional and vacuum reflowed test vehicles was characterized and compared using two different accelerated thermal cycling profiles. The thermal cycling results are discussed in terms of the general impact of voiding on solder thermal fatigue reliability, results from the open literature, and the evolving industry standards for solder voiding. Recommendations are made for further work based on other void reduction methods and additional reliability studies.

To stake a claim in upcoming new technologies and increasing improved customer experience, it is now becoming a central point of consideration to bring out the new classy vehicle design, car manufacturing techniques, testing system in the global market. The current vehicle manufacturer’s also aim to maintain equilibrium between deep capital investment and long product cycle to make the car model a success story. With this, the type of printed circuit board to be used in the vehicle is decided with focusing more on the type of material used in the vehicle and the level of electronic manufacturing and design solution needed in the vehicle production. To go into the roots of the automotive industry, it is equally important to get insights into the PCB used in vehicles and the new innovations brought forward by researchers to create a dream vehicle of the series. The below paragraph drives you to the types of PCB used in the automotive sector.

V2V is a collision avoidance technology that transmits data between vehicles to help warn drivers of potential crashes. This technology would improve safety by allowing vehicles to communicate with each other and exchange basic safety data, such as position and speed and warn the driver of potentially dangerous situations.

The architecture of vehicle electrical systems is changing rapidly. Electric and hybrid vehicles are driving mixed voltage systems, and cost pressures are making conductor materials like aluminum an increasingly viable competitor to copper. This paper presents tradeoff studies at the vehicle level, and how to automatically generate an electrical Failure Mode Effects and Analysis (FMEA) report, as well as how to optimize wire sizes for both copper and aluminum at the platform level.

Autonomous vehicles have the potential to revolutionize the automotive industry and are gaining immense attention from academia as well as industry. However, facets of autonomous vehicle systems related to the interconnection of independent components pose vulnerabilities to the system as a whole. These vulnerabilities aren't guaranteed to be solved by traditional security methods. Blockchain technology is a powerful tool that can aid in improving trust and reliability in such systems.

The benefits of autonomous vehicles (AVs) are widely acknowledged, but there are concerns about the extent of these benefits and AV risks and unintended consequences. In this article, we first examine AVs and different categories of the technological risks associated with them. We then explore strategies that can be adopted to address these risks, and explore emerging responses by governments for addressing AV risks.
