  • RM 155: Ultra HDI Panel Discussion - Recorded Live at SMTAI

    Today's podcast comes from the Surface Mount Technology Association SMTAI trade show.

     

    As the demand for smaller, faster, and more powerful devices grows, the need for innovative solutions in circuit design has never been greater. UHDI's represent a significant leap forward, allowing for more connections in a smaller space, pushing the boundaries of what's possible in electronic assemblies.

    But what exactly are ultra-high-density interconnects? Essentially, they refer to circuit boards with incredibly fine pitch interconnects, enabling higher functionality and complexity in much smaller form factors. 

    This breakthrough is transforming industries like consumer electronics, aerospace, automotive, and medical devices, where space, weight, and performance are critical factors.


    In this episode, we’ll explore the advantages UHDI's bring to the table, from increased design flexibility and performance to better thermal management. We'll also discuss how UHDI's are set to impact the assembly process. With tighter tolerances and more intricate layouts, UHDI assemblies will require new approaches to assembly, inspection, and reliability testing.

    To better explain UHDI technology, we’ve put together a panel of subject matter experts. Tara Dunn, director of training and education at SMTA, will moderate a panel discussion with other subject matter experts, including Anaya Vardya, CEO, of American Standard Circuits; Chrys Shea from Shea Engineering Services; Michael Sivigny, owner and general manager of CeTaQ Americas; and Oren Manor, Op-Center core program business director at Siemens Digital Industries Software.

    UHDI is here! And if you haven’t seen it on your assembly line yet, it’s coming, so stay tuned as we unpack the future of ultra-high-density interconnects and what it means for the next generation of technology.

  • RM 153: Contract Manufacturing Best Practices with Adrian Leal

    If you're part of the electronics landscape, you've likely encountered the role contract manufacturers play — and it's a critical one. These specialized partners bridge the gap between design innovation and full-scale production, bringing efficiency, expertise, and flexibility to the table.


    As companies seek to meet growing demand for advanced electronic products, contract manufacturers are increasingly relied upon to provide cost-effective, high-quality assembly services. Whether it's managing supply chains, ensuring compliance with industry standards, or accelerating time to market, their contributions have become indispensable. In today's episode, Mike Konrad explores how contract manufacturing works, why it's so vital, and what trends are shaping the future of this essential industry.

    Adrian Leal serves as USA business development manager for Teltonika EMS and is president of the Houston SMTA Chapter. With over 30 years of experience in the manufacturing industry, he has worked extensively as both an end-user and a service provider. Throughout his career, he has held diverse roles including process engineer, manufacturing engineer, quality engineer, field engineer, and sales engineer.

    In 2003, Leal became the first engineer from the oil and gas industry to earn the prestigious Process Engineer certification from the SMTA. From 2006 to 2015, he voluntarily took on the role of ESD Subject Matter Expert for SLB, where he developed an internal ESD program that remains in use today.

    Leal talks about his transition from an OEM to a contract manufacturer and recommendations on how to choose the most appropriate contract manufacturer.
