https://calce.umd.edu/plastic-materials-microelectronics
Historically, PEMs have been used in commercial and telecommunications electronics and consequently have a large manufacturing base. With major advantages in cost, size, weight, performance, and availability, plastic packages have attracted 97% of the market share of worldwide microcircuit sales, although they encountered formidable challenges in gaining acceptance for use in government and military applications. Today, high-quality, high-reliability, high-performance, and low-cost plastic-encapsulated microcircuits are common. Thanks to new packaging materials, improved design, increased reliability testing, and other important developments, PEMs are not, in many cases, the most cost-effective option for a wide range of electronic systems applications.

https://calce.umd.edu/counterfeit-parts-detection-using-sae-as6171
The SAE AS6171 family of standards was developed by the G-19A Test Laboratory Standards Development Committee.  The general requirements document sets out requirements and recommendations for risk assessment, test selection, sampling criteria, training, workmanship, and reporting associated with the detection of counterfeit parts. The slash sheets govern a wide range of test methods as well as a method for developing a test plan that balances the investment of resources for testing against the level of risk associated with the parts and end-use application. AS6171 servers as a comprehensive testing standard and a methodology for risk-based testing within any counterfeit prevention strategy.

https://calce.umd.edu/use-component-documentation-and-supply-chain-counterfeit-avoidance-workshop-0
There is NO alternative to good supply chain management as a defense against counterfeit parts. Understanding the supply chain and assessing the supply chain before engaging them are necessary steps for any organization. This part of the course will cover how to understand and utilize process change notices for making supply change management and counterfeit detection more efficient. The role of counterfeit part reporting as a legal and technical tool along with its promises and limitations will be discussed with examples. The impact of the US DoD rule changes on the supply chain will be introduced.

https://calce.umd.edu/uprating
The ratings on electronic parts and selection of their use for an application environment are a matter of concern for engineers in all industries. There are standards available for derating of parts that are not application specific and often outdated. This course will discuss the part ratings, how ratings are developed, and what their implications are in selecting the use environment for parts to meet the reliability and performance requirements of the system. This course will also introduce the participants to the design, assembly, test, legal and cost issues related to uprating. To stay competitive, both technically and economically, industries may need to consider using parts whose data sheet temperature limits are not broad enough to meet the application environment.

Waste heat with a temperature lower than 650°C accounts for a huge amount of total energy consumption. It is important to recover waste energy in this temperature range for sustainability. Attractive options to recover waste heat are converting it to electricity, industrial heating and space heating or cooling based on the waste heat temperature level. This course will provide a background of waste heat recovery technologies. Multiple thermodynamic cycles that utilize different levels of waste heat, including organic ranking cycles, supercritical CO₂ cycles, high temperature heat pumps, thermally driven heating/cooling (absorption and adsorption) technologies, will be illustrated. A simulation tool – such as Engineering Equation Solver (EES) may be introduced for cycle simulation depending on participants’ interest.

Combined energy systems utilize renewable energy sources, waste heat and thermally driven cooling technologies to simultaneously provide energy in multiple forms. They are reliable by virtue of main grid independence and ultra-efficient because of cascade energy utilization. These merits make combined systems potential candidates as energy suppliers for such applications as commercial buildings, campuses, neighborhoods and hospitals. This course will cover the fundamentals of combined energy systems, including system design optimization and operational strategies. Energy efficiency, emission reduction and economic models will be presented and discussed in the form case studies.

https://calce.umd.edu/accelerated-product-qualification
Accelerated stress testing is one of the key resources in the physics of failure (PoF) approach and helps simulate product life cycles over compressed time periods by accelerating the damage accumulation rate for relevant wear out damage mechanisms. If done early in the development phase, in conjunction with reliability science design, accelerated testing can enhance process and design maturity and enable early introduction of mature products with robust design margins. Efficient testing requires an understanding of test methods, test stresses, test results, and correlation to field life.  Participants will learn how to make accelerated stress testing a value-added activity and use test results to take pro-active, corrective measures early in the design and production phases to ensure reliability and quality.

In the course of engineering design, project management, and other functions, engineers have to make decisions, almost always under time and budget constraints. Managing risk requires making decisions in the presence of uncertainty.  In this course students will develop two critical skills: choosing the right alternative and executing the right decision-making process.  These skills will help students improve decision making and reduce risk in their engineering activities and organizations.  This course will cover material on individual decision making, decision-making processes, and risk management. The course will present techniques for making better decisions, for understanding how decisions are made, and for managing risk.  The course is designed for engineers and professionals who are comfortable with logical reasoning, calculation, probability, mathematics, and optimization, but it does not require advanced theoretical mathematics.

https://calce.umd.edu/critical-system-sustainment-5
“Sustainment” (as commonly defined by industry and government), is comprised of maintenance, support, and upgrade practices that maintain or improve the performance of a system and maximize the availability of goods and services while minimizing their cost and footprint or, more simply, the capacity of a system to endure. Sustainment is a multi-trillion-dollar enterprise for critical systems, in both government (infrastructure and defense) and industry (transportation, industrial controls, data centers, energy generation). This course introduces the important attributes of system sustainment by integrating the data analytics, engineering analysis, and public policy necessary to develop technologies, processes, and policies aimed at sustainment management processes and practices.
