Following our visit to the Automotive Interiors Trade Show in November, ALT Technologies attended LOPEC, the printed electronics industry’s leading trade show.
ALT Technologies attended the 2023 International Exhibition and Conference for the Printed Electronics Industry, LOPEC, at the International Congress Center in the Messe Munich. Our business development managers, Mario Schmid and Abdoulaye Ndoye took part in the three-day event to speak with the showcasing companies about the latest developments in automotive printed electronics.
After the trade show, we spoke with Mario about his findings and what sparked their interest in the printed electronics realm.
As the world of printed electronics opens up and becomes more accessible to everyday appliances, all technologies involved in the process are advancing rapidly.
A huge benefit of printed electronics is the ease of access to prototyping. Without needing a clean lab and energy-draining processes, you can hook up a 3D printer to your laptop and quickly and cost-effectively develop a prototype at your desk with flexible substrates.
Another barrier with circuit boards was rigidity and product development, but now as flexible circuits take hold, their capabilities are expanding. The conductive inks enable even higher conductivity and fast drying (<2sec). This allows manufacturers to produce faster and more ongoing (roll to roll) because drying is integrated with the machinery and process.
Connectors such as ZIF (zero insertion force) are commonly used to connect flex circuit boards with rigid boards, but other mechanical solutions such as crimp contacts and interposer connectors are coming to the fore.
The machinery and processes used to develop printed electronics solutions are advancing rapidly. The varying possibilities to produce FPE (flexible printed electronics) depend on the customers’ needs. This spans the type of ink used, adding different ink, milling, lasering, and cutting copper or other metals on the surface.
The wide range of printing solutions adds even more value to the end products; sensors, IC, and NFC capabilities.
The standout solution for Mario was the multilayer FPC (flexible printed circuit) used in air conditioning units with integrated touch and slide functions to easily adjust the temperature.
The LOPEC show gave our team a lot of food for thought and inspiration in the printed electronics realm. The capabilities for printing and developing flexible materials and substrates are at an all-time high, and we are excited to play a part in this area. Our experience working with and developing strong and durable material solutions allows us to broaden our range to include printed electronics.
