Henkel Tackles Challenging 5G, Power, Automotive and Aerospace Applications at IPC APEX

Reading time ( words)

At next month’s IPC APEX EXPO electronics event in San Diego, CA, Henkel’s exhibit and conference participation will highlight the materials leader’s latest innovations and the scope of its portfolio, which offers ‘solutions across the board’ for multiple applications. Henkel’s aggressive product development initiatives have resulted in advanced thermal management materials for next-generation 5G infrastructure systems, semi-sintering materials that address demanding aerospace reliability requirements, and low voiding solder pastes that help ensure electrical and mechanical reliability for power electronics.
Visitors to IPC APEX EXPO are invited to meet with Henkel technologists in booth # 3603 to learn more about:
High Performance Materials for Tough Operational Environments
  • High Thermal Conductivity, Ultra-Low Modulus TIM -- Controlling the heat generated by 5G telecom infrastructure and consumer mobility devices while minimizing assembly stress is becoming more difficult as power densities rise within increasingly smaller footprints. Soft, compliant, ultra-low modulus BERGQUIST® GAP PAD® TGP 10000ULM thermal interface material (TIM) strikes this balance, with a thermal conductivity of 10.0 W/m-K, which is among the highest lambda values available on the market today for low modulus TIM pads.
  • Low Voiding Solder Paste – The need to minimize internal temperature in order to extend component lifetime is driving the requirement for low voiding solder materials. Eliminating hot spot formation presumed to be caused by voids in the interconnect material helps improve electrical and mechanical reliability, which is critically important for power and industrial automation applications which are often operational 24/7. LOCTITE GC 18 is the latest addition to the award-winning LOCTITE GC materials portfolio with market-leading performance of less than 25% voiding on large QFNs (>8.0 mm x 8.0 mm) and <10% on small QFNs (< 8.0 mm x 8.0 mm).
  • Semi-sintering Materials -- Aerospace applications, most notably radar systems, require board-level assemblies and power semiconductors to cope with high current densities and effective heat dissipation. Simultaneously, performance chips that integrate Gallium Nitride (GaN), Gallium Arsenide (GaAs) and Silicon Carbide (SiC) have higher operating temperatures (>200°C) which soft solder and silver-based adhesives cannot survive. LOCTITE® ABLESTIK® ICP 9000 series semi-sintering interconnect materials offer exceptional thermal performance to cope with the demands of high-power density aerospace applications.
Technology Expertise

For conference attendees that want to dive deeper into materials capabilities and practical application, presentations from several Henkel technologists offer additional educational opportunities. The following paper and poster presentations will be delivered throughout the three-day event:
  • Course: Thermal Management Using Thermal Interface Materials, Dr. Rita Mohanty, Henkel Director of Application Engineering and Technical Customer Service, Feb. 3, 9:00 am – 12:00 pm.
  • Paper Presentation: A Hybrid Sintering Technology for High-power Density Devices Used in Aerospace Applications, Yuan (David) Zhao, Henkel Principal Engineer, Technical Customer Service, Feb. 5, 1:30 pm – 3:00 pm.
  • Paper Presentation: Liquid Dispensed Thermal Materials for High-Volume Manufacturing, Sanjay Mirsa, Henkel Senior Scientific Principal, Feb. 6, 9:00 am – 10:00 am.
  • Poster Sessions will take place on Feb. 4 from 10:00 am – 10:30 am and Feb. 5 from 4:30 pm to 5:00 pm in the Ballroom 20 Foyer. Henkel’s Dr. Mark Currie and Neil Poole will present the below:
    • Compatibility Secures Reliability – Understand how solder flux compatibility (or lack thereof) with underfills, encapsulants, conformal coatings and other board-level materials can impact reliability.
    • Solder Solutions for Harsh Environments – Conventional SAC alloys do not meet the stringent reliability standards for many systems that operate within harsh environments, such as automotive. Learn about a lead-free alloy designed to cope with tough conditions.

Taking Charge of ESD

04/25/2023 | Barry Matties, I-Connect007
At the recent SMTA Boise Expo & Tech Forum, Barry Matties spoke with Doug Holtz, national sales manager of Conductive Containers, about challenges related to ESD and where manufacturers are most vulnerable. It’s a growing concern, Doug says, and there are important lessons to be learned. Doug also reviews his presentation, and he points out how reducing touchpoints in the supply chain can make a world of difference for both customers and manufacturers.

EPTAC: Think Globally, Act Locally

04/12/2023 | Andy Shaughnessy, Design007 Magazine
At the recent Dallas SMTA Expo and Tech Forum, I spoke with many of the 100 exhibitors who dotted the exhibit floor. David Thomas, an IPC master instructor at EPTAC, was running the training company’s booth there. I asked him to update me on EPTAC’s latest efforts and to discuss the value of exhibiting at local events like this one.

The Need for Real-time Measurements on the Factory Floor

04/05/2023 | Barry Matties, I-Connect007
During SMTA Dallas Expo 2023, Barry Matties spoke with Morgan Miller, field application engineer at Insituware, about the need for real-time measurement capabilities, like the Vision MARK-1 device offers, which is powered by analytical sensors, machine learning, and cloud-based technology to bring materials control solutions right to the factory floor.
