3A) The 6 Hazards of Product Safety
William Bisenius, President and co-founder, CertifiGroup
Abstract: We all use electrical products as a daily part of our personal and working lives without realizing the potential hazards these products present. Even now, with frequent news stories telling us of people who were injured by their e-cigarette or cell phone, we assume that the products we use will be fine. In the United States, electrical products bear the “UL” mark to indicate that they comply with the applicable UL standard and are therefore safe for use. There are over 600 UL safety standards for various types of electrical products. All electrical product manufacturers in the US need to build their products to comply with these standards. All manufacturers in the US need to choose safe products for their employees to use. Yet there is no university in the world that teaches product safety. This presentation will teach you the “6 Hazards of Product Safety”. Product compliance standards and governing requirements can be difficult to read, understand, and more importantly apply without knowing the intent of the requirements. This presentation will greatly help ALL safety professionals from beginner to advanced. By understanding the “6 Hazards of Product Safety”, you will better understand the hazards presented by electrical products, thereby allowing you to make better personal and work decisions related to the development, implementation, and use of electrical products. Whether your company makes a product or just uses electrical products, this knowledge will benefit you for the rest of your life.
3B) A “Chicken or Egg” Approach to Electromechanical Product Design
Sam Felts, Head of Product Development - Touchstone 3D
Sarah Hall, Mechanical Engineer - Touchstone 3D
Abstract: Which came first, the chicken or the egg? How do industrial design, mechanical engineering, and electronics engineering influence each other? Should you design the product first, and hope the electronics fit? Or should you engineer the electronics, and then try to wrap a product around it?
Join us to discuss how to successfully integrate these disciplines into a product that consumers want and avoid costly design iterations.
3C) Making Intelligent Material Decisions
Michael R. Creeden, Technical Director Design Education - Insulectro
Abstract: In meeting today’s dense, high-speed circuits that have competing requirements. With this presentation, attendees will learn solutions to help avoid the most common failure points in today’s Printed Circuit Engineering Layouts. Attendees will walk away with real world applications for success, they will receive an understanding of how to implement pro-active solutions rather than re-active responses. Meeting these competing perspectives without compromising any one of them must be considered because they all play a part in the design, manufacturing, and performance of our end products. Failure can come in the following forms.
- Physical, electrical, environmental perspectives of our materials
- Technically appropriate material selection
- Technical performance, (SI) signal integrity/EMC applications
- High manufacturing reliability and producibility and yield
The focus will be on practical application and implementation using real world examples
3D) Place and Route for Dense High-Speed and RF Circuits

4C) Advanced Processes to Meet Today’s Design Challenges
Paul Cooke - Field Application and Technical Sales Manager, AGC - Taconic Materials
Abstract: Designing printed circuit boards (PCB) and assemblies is more difficult than ever due to complexity, component availability, thermal requirements, signal integrity, material selection, layer counts, harsh environments and increased functionality all required in smaller form factors. We will look at all the elements to successfully manufacture a PCB that can meet all the designers’ requirements and perform to the customer and industry standards as well as survive in today’s harsh environments. We will look at some of the more advanced process’ and materials being adopted by the fabricators to produce smaller, thinner more reliable and faster production times to meet quick turn requirements. We will look at various processes and materials including plating shut, interposer designs, high reliability, high layer 5+ stacked microvia designs with 3 mil microvias, heavy copper solutions, and new hole fill processes without the need to planarize. All these processes need to ensure the product is robust as possible with a high level of confidence that it has been designed for extended life in the field.

5B) Engineering Reliability with Epoxy and Urethanes
Brian Hanson, Vice President of Sales - EFI Polymers Inc.
Abstract: As automotive, battery, and electronics technology continues to develop, the need to push more power and capability through electronics grows. As we continue to rely more and more on electronics, the need to protect those electronics from heat, water, dirt, dust, vibration and other contaminants also grows. Epoxies and urethanes have been used to protect electronics for over 50 years. However, many companies view potting and the potting process as difficult, expensive, and prone to quality issues. This white paper seeks to provide an overview of potting materials, and how to better incorporate them into your manufacturing process including how potting materials help with thermal management, how physical properties impact the finished parts, and the importance of designing with processing in mind.
5C) Solid Liquid Hybrid TIMs
Miloš Lazić, Product Development Specialist (TIMs), Certified SMT Process Engineer) - Indium
Abstract: For many years, metals have been used as thermal interface materials (TIMs) in the industry. With high-reliability and high thermal conductivity, metals have been a great solution, especially for challenging applications. Thermal properties of any TIM are defined by their thermal conductivity and interface resistance. The biggest obstacle for metal TIMs to overcome is interface resistance. Because most metals are very stiff, a certain amount of pressure needs to be applied to form a close connection between the materials, thus lowering interface resistance. As electronic devices are continually getting smaller, consuming more power, and producing more heat, finding the right TIM becomes one of the top priorities in any application. Solid liquid hybrids (SLHs) are the next generation of metal TIMs. SLHs are a combination of metals that are solidus at room temperature with ones that are liquidus at room temperature. With low thermal resistance and low bondline thickness, SLHs are the perfect solution for certain high-end applications. This paper will discuss the possible applications where SLHs can be used, as well as challenges and obstacles that still need to be overcome to encourage adoption across the industry.

6A) PCB Weave mitigation/fundamentals in PCB and PCB Skew Measurement and system BER skew effects with Keysight equipment
Steve Scearce - Principal Engineer/Engineering Manager of Cisco’s Electronics Packaging and Diagnostics team - Cisco
Abstract: The glass weave effect on current and next generation PAM-4 systems have shown bit error rate issues in the Lab. Our lab results show that our PAM-4 systems are more sensitive for PN skew than previous generations of NRZ with the same UI. For the current generation of designs we must consider glass direction, glass type, weave pitch, art work rotation, and weave density. Future Stackup decisions are based on the on the measured network parameters, TDR, silicon BER, and system eye diagram measurement results. Techniques used to mitigate the unbalance effect of the glass weave with differential pairs are discussed here and statistical measurement results will be shared. In addition we are partnering with Keysight to facilitate lab skew measurements and actual BER degradation effects on signal error rates due to the system skew effects.
6B and 6C) Component and Wiring Considerations for PCB Designers (Parts 1 and 2)
Dr. Bruce Archambeault, Retired and Jay Diepenbrock, SIRF Consultants
Abstract: This presentation will discuss several principles that are important for PCB designers for good Signal Integrity, Power Integrity, and Electromagnetic Compatibility (EMC). A brief review of the theory behind each principle will be presented, followed by a practical demonstration using a PC board and test equipment. The principles to be discussed include:
• Self-inductance and the effect of wire conductor size and distance from the return path (loop area);
• Lenz’ Law, which is physically the same as self-inductance but in this case applies to PCB traces over return planes;
• Crosstalk, which is undesired energy coupled to neighbor traces from a driven trace. The phenomena of critical frequency, resonance, and influence of termination and return plane gaps will be demonstrated;
• Inductance of Capacitors, which is influenced by the length of connecting traces, capacitor packaging and dielectric material, and even the value of the capacitor itself;
• Electrical effects of traces routed over return plane gaps (splits).
Some of these may be things you never thought you had to worry about, and the results may surprise you.
