Printed Circuit Boards (PCBs) are key components of any electronic product. Any error in the design or assembly of the PCB can lead to product failure.

Electrical engineers are under increasing pressure to design smaller, flexible and more efficient PCBs to meet consumer demand for wearables, smartphones, 5G and Internet of Things (IoT) devices.

Increase your customers’ confidence by demonstrating that your PCB is not only compliant to regulatory safety requirements but also tested to perform reliably. UL’s performance testing and certification programs apply to a comprehensive range of PCB designs and materials.

Protect your products’ reputation by testing with UL. For more than 50 years, UL has been advancing safety science in support of PCB conformance assessments, now also covering extensive performance testing options which can help enhance your products’ reputation for reliability.

Why UL?

UL is the only organization that issues PCB safety standards. Make use of our technical expertise in safety testing and certification services to achieve regulatory compliance as well as communicate to customers that your product has been tested to the benchmark of product safety.

UL’s extensive relationships across the entire printed wiring board supply chain have manufacturers turning to us when they are looking for reliable components from trustworthy sources. Your customers will also value how UL assists them to eliminate duplicate testing of the finished end products when they contain UL Recognized components.

All testing can be conducted in UL accredited laboratories or in your own qualified facilities. We can accelerate testing to your time frame. View UL’s PCB solutions brochure.

UL PCB Recognition Program

PCB components and materials that are recognized by UL are known to have undergone the industry’s most stringent safety testing and follow-up program. UL Recognized Components are listed in UL’s Online Certifications Directory  and the UL iQTM database. This allows your customers to search and identify the components and materials they need to complete their subassemblies or end products.

The global electronics movement toward smaller and less expensive products requires printed circuit board (PCB) thermal management solutions that keep product development moving.

Using printed circuit boards that have been pre-selected and pre-certified can save you time and money. Supply chain communication about PCB products is also critical to ensuring quality and your brand reputation. UL tests for performance the printed circuit boards that go in products as well as the end products themselves.
