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.

The Evolution of Picosecond Laser Drilling
06/19/2025 | Marcy LaRont, PCB007 MagazineIs it hard to imagine a single laser pulse reduced not only from nanoseconds to picoseconds in its pulse duration, but even to femtoseconds? Well, buckle up because it seems we are there. In this interview, Dr. Stefan Rung, technical director of laser machines at Schmoll Maschinen GmbH, traces the technology trajectory of the laser drill from the CO2 laser to cutting-edge picosecond and hybrid laser drilling systems, highlighting the benefits and limitations of each method, and demonstrating how laser innovations are shaping the future of PCB fabrication.
Day 2: More Cutting-edge Insights at the EIPC Summer Conference
06/18/2025 | Pete Starkey, I-Connect007The European Institute for the PCB Community (EIPC) summer conference took place this year in Edinburgh, Scotland, June 3-4. This is the third of three articles on the conference. The other two cover Day 1’s sessions and the opening keynote speech. Below is a recap of the second day’s sessions.

Preventing Surface Prep Defects and Ensuring Reliability
06/10/2025 | Marcy LaRont, PCB007 MagazineIn printed circuit board (PCB) fabrication, surface preparation is a critical process that ensures strong adhesion, reliable plating, and long-term product performance. Without proper surface treatment, manufacturers may encounter defects such as delamination, poor solder mask adhesion, and plating failures. This article examines key surface preparation techniques, common defects resulting from improper processes, and real-world case studies that illustrate best practices.
RF PCB Design Tips and Tricks
05/08/2025 | Cherie Litson, EPTAC MIT CID/CID+There are many great books, videos, and information online about designing PCBs for RF circuits. A few of my favorite RF sources are Hans Rosenberg, Stephen Chavez, and Rick Hartley, but there are many more. These PCB design engineers have a very good perspective on what it takes to take an RF design from schematic concept to PCB layout.
