UL certification is one of an engineer’s least favorite topics, yet it is critically important. The process is complicated but relatively straightforward for standard rigid PCBs, but as Jan Pedersen makes clear in NCAB Group’s recent webinar, “UL Approval for Flex and Flex-Rigid PCBs,” it is a very different story.
In this webinar,” Pedersen, director of technology at NCAB Group, delivers a detailed, experience-driven explanation of why UL certification has become such a challenging aspect of flex-rigid design. He also explains why assumptions based on rigid boards often lead to costly surprises. For engineers designing flex or flex-rigid PCBs, or managing products that must carry UL approval, this webinar offers practical clarity in a space that is often opaque, misunderstood, and expensive to navigate.
UL is frequently assumed to be a government body, but Pedersen corrected that misconception. UL is an independent product safety certification organization, not a U.S. government agency. That said, it is formally recognized by key federal bodies, including OSHA, the FCC, and the Consumer Product Safety Commission. UL certification is important for Canada and Mexico, making it essential for products entering the North American market. While UL may not be government-run, it is effectively mandatory for many products.
