Presentation Title: Heterogeneous Integration (HI): An Enabler For Next Generation Systems
Abstract: To perform increasingly diverse missions in increasingly crowded EM environments, future sensor and communication systems will require increased bandwidth and sensitivity and enhanced functionality per unit area. These needs are driving sensor arrays towards higher levels of integration of a diverse set of materials, devices and components across multiple domains. This includes 3D solutions, particularly at millimeter wave and THz frequencies. This talk will present an overview of the evolution of heterogenous integration programs at DARPA and potential paths forward, including 3DHI at the transistor level being explored under the DARPA Heterogeneous Heterostructures (H2) and related programs.

Presentation Title: Thermal Challenges for Future Military Platforms
Abstract: Modern land, sea, and air warfare technologies are trending towards significantly higher power loads with transient behavior that present unique challenges in thermal system design. Traditional design approaches assume steady state operation and rely on overdesign to meet worst-case scenarios. Moreover, advanced control techniques are virtually absent in most thermal systems. Therefore, tremendous opportunities exist to reduce the size, weight and power consumed by thermal management systems associated with these loads through the development of innovative components, the design of energy efficient system architectures, and their effective integration onto military platforms. This talk will discuss recent progress, as well as remaining research challenges, related to cooling of dynamic thermal loads.

Presentation Title: Pushing The Boundaries of Thermal Packaging for Enhanced Performance And Energy Efficiency
Abstract: With the advancement of cloud technologies and data centers, artificial intelligence, machine learning, and IoT-based data communications and operations, the power consumption of information and communication technology (ICT) has skyrocketed in recent years. Datacenters alone are estimated to consume 75 TWh/yr of electricity annually (approximately 2 percent of total US electricity consumption), and this consumption is expected to grow exponentially with exploding demand. However, the chip scaling efficiency (Moore's law) reached a tipping point in 2016, and conventional and incremental technological improvements to reduce electric power consumption have reached their limit, with the efficiency curve plateauing.
To make the next leap, transformative improvements in both performance and efficiency, as well as cost reductions, are required. Inefficiencies in complex, heterogenic integration of high powder density electronics result in inefficient power use and a large amount of waste heat, both of which must be managed for the reliable and efficient operation of ICT components and systems. Microscale thermomechanics and thermal management have become increasingly important as electronics have shrunk, but they are extremely difficult to understand and control due to the transient and spatially isolated nature of components or environments. Rather than dealing with thermal management in electronic devices as an afterthought, it is critical to employ a co-design approach early in the process to enable new designs. Quantum computing is rapidly approaching as a viable and unavoidable solution, with potential end use cases in a wide range of industries. However, for large-scale and cost-effective applications, better cooling solutions are critical. Transformational designs, materials, and manufacturing methods are needed, among other things, to reduce the cost and size of the associated cryogenics systems.
I will provide an overview of ARPA-E’s past and current program areas related to this problem, followed by a discussion of potential technology areas to push the boundaries of thermal materials and interfaces to enable the establishment of next generation electronics packaging.

Presentation Title: Use of AI and ML in Improving Industrial Reliability towards Achieving Operational Autonomy – Successes and Challenges
Abstract: Predictive Maintenance (PM) is becoming ubiquitous for improving availability and reliability along with reducing O&M costs in industrial systems. Despite significant research and development investment in the last decade most deployed solutions still tend to be piecemeal (component or failure mode specific) point solutions and generally lack trust with respect to automated decision making. Full end-to-end deployment with system-wide coverage and autonomy still remains an elusive goal in industrial setting. This is primarily due to high cost and limited scalability of conventional modeling approaches for underlying complex systems and processes in large fleets. Specifically, capabilities to safe-guard against unknown-unknowns, lack of explainability and trust tend to be key bottlenecks. Given these systems are heavily instrumented generating large volumes of high-speed data and compute costs continue to go down, recent advancements in data-driven methods using machine learning (ML) and artificial intelligence (AI) have shown promise in a number of areas that previously led to valley of death between PM technology and commercialization. GE’s Digital Twin technology for Predictive Maintenance is leveraging AI to bridge a number of such critical gaps that were otherwise very challenging to tackle through conventional methods. This session will enumerate key challenges in enabling system-wide predictive maintenance and how AI is being used to overcome these. Specifically, a causal deep learning-based approach will be described that provides a causal graph of inter-variable relationships allowing validation of deep learning model with domain experts. Further, by providing causal factors for identified anomalies root cause analysis can be facilitated for alert disposition in efficient manner at the fleet level. We will also describe our approach towards competency awareness of AI models, which aims to solve uncertainty management and trust for industrial applications of AI. Various applications and use-cases will be shared to show effectiveness of AI and ML using both structured and unstructured data in the context of intelligent PM.

Presentation Title: Multilayer Flexible Electronic Devices for IoT and RF Applications
Abstract: Boeing is actively engaged in the development of Flexible Hybrid Electronics. Our team prototypes various antennas, IoT devices, radar boards, and low cost conformal phased arrays. We began with single layer processes and have expanded rapidly prototype development of multilayer flexible printed circuit boards (Flex-PCBs) for size weight power and cost saving applications. Flex PCBs allow electronics to be wrapped onto cylindrical or bi-axial curved surfaces. Conventional Flex PCBs contain either one to six copper layers with limited electronic packaging. Most devices are bonded to rigid boards that contain complex packaged electronics. Boeing's processes, however, apply copper clad or printed inks on polyimide substrates to build fully functional flex-PCBs between two and eight conductive layers thick. Thus allowing antennas, sensors, communication links, and radars to be placed directly onto the surface of a vehicle. Similarly, power routing, and microcontrollers can conform to surfaces or interior cavities. This technology represents a transformative approach to PCBs in aerospace applications.
Our team has demonstrated this capability on RF boards with no less than 500 through vias, 100 buried vias, and 50 electronically packaged components. Complex boards can be turned in days without electroplating. Pyralux AP polyimide substrates from DuPont, Taconic, and 3M bonding adhesive achieves alignment errors of 2 mil or less over an 8 x 10 square inch area. Kapton substrates have been used with ink jet printing of particle free silver and UV curable dielectrics to create three layer IoT devices. Vias are filled using conductive inks. Electronic packaging is currently performed using anisotropic conductive epoxy, silver ink, or low temperature solder. Cost models have been completed for printed silver devices, documenting the manufacturability from Manufacturing Readiness Levels (MRL) 4 to 6. We are currently examining pilot capability of different suppliers to manufacture devices at volumes needed for commercial activities.
