Automotive Radar Applications
The development of a stable dielectric performance and low modulus copper-clad laminate for automotive radar applications was described by Yonghyon Kim, senior engineer with Doosan Corporation Electro-materials.
He reviewed the technological trend for radar sensors and the laminate requirements for automotive radar operating at 77–79 GHz frequencies. To minimise mechanical stress, a low-modulus material is necessary, and he described a filled fluoroplastic material without woven glass reinforcement. This gives advantages in mechanical drilling together with dielectric uniformity and CAF-resistance as well as outstanding high-frequency performance, making it an excellent choice for automotive radar applications.
Kim gave a comprehensive list of material properties and examples of reliability test results, particularly heat aging and thermal cycling.
He concluded by demonstrating that the mega-trend toward smart mobility will necessitate hyper-connectivity and convergence in a whole series of industries, and described the range of copper-clad laminate material solutions offered by Doosan.
Conclusion
At the end of the day’s conference proceedings, we took a short bus journey to BMW World, where we saw many shiny motor cars, BMW, Mini, and Rolls Royce, and some desirable motorcycles, as well as learning about thousand-dollar umbrellas and hand-painted coach-lines.
In the evening, we took the bus downtown to a traditional Bavarian restaurant overlooking the opera house Spatenhaus an der Oper, for a splendid networking dinner.
Note: My thanks to Alun Morgan for the excellent photographs.

Connect the Dots: Stop Killing Your Yield—The Hidden Cost of Design Oversights
04/03/2025 | Matt Stevenson -- Column: Connect the DotsI’ve been in this industry long enough to recognize red flags in PCB designs. When designers send over PCBs that look great on the computer screen but have hidden flaws, it can lead to manufacturing problems. I have seen this happen too often: manufacturing delays, yield losses, and designers asking, “Why didn’t anyone tell me sooner?” Here’s the thing: Minor design improvements can greatly impact manufacturing yield, and design oversights can lead to expensive bottlenecks. Here’s how to find the hidden flaws in a design and avoid disaster.
Real Time with... IPC APEX EXPO 2025: Tariffs and Supply Chains in U.S. Electronics Manufacturing
04/01/2025 | Real Time with...IPC APEX EXPOChris Mitchell, VP of Global Government Relations for IPC, discusses IPC's concerns about tariffs on copper and their impact on U.S. electronics manufacturing. He emphasizes the complexity of supply chains and the need for policymakers to understand their effects.
The Chemical Connection: Surface Finishes for PCBs
03/31/2025 | Don Ball -- Column: The Chemical ConnectionWriting about surface finishes brings a feeling of nostalgia. You see, one of my first jobs in the industry was providing technical support for surface cleaning processes and finishes to enhance dry film adhesion to copper surfaces. I’d like to take this opportunity to revisit the basics, indulge in my nostalgia, and perhaps provide some insight into why we do things the way we do them in the here and now.
NUS Physicists Discover a Copper-free High-temperature Superconducting Oxide
