What is BS EN 62326-20 - Printed circuit boards for high-brightness LEDs about?  
BS EN 62326-20 is an international standard that discusses printed circuit boards for high-brightness LEDs, ensuring safety, performance and longevity in electrical applications.
BS EN 62326-20 specifies the properties of the printed circuit board (hereafter described as PCB) for high-brightness LEDs. Many aspects of the PCB for high-brightness LEDs are identical to those of ordinary PCBs, therefore, some aspects of this standard also describe general aspects.
Who is BS EN 62326-20 - Printed circuit boards for high-brightness LEDs for? 
BS EN 62326-20 on printed circuit boards for high-brightness LEDs is useful for: 
- Manufacturers of printed circuit boards (PCBs)
- Dealers and importers of printed circuit boards (PCBs)
- Testing houses and labs for circuit boards and LEDs
- Manufacturers of electronic components
- Quality control and testing personnel
- Inspection authorities
Why should you use BS EN 62326-20 - Printed circuit boards for high-brightness LEDs?  
The Printed Circuit Board (PCB) is essential in all electronic devices, whether they are used for residential or industrial applications. In a multi-processor context, the interconnection arrangement can determine total system performance.
BS EN 62326-20 provides guidance on classification and class of the printed circuit board for high-brightness LEDs, performance and test methods, quality, design rules, and allowance, enabling the reduction of errors and short circuits in LED applications.
BS EN 62326-20 provides users guidance on design rules and allowance including, panel and board sizes, total board thickness, holes, conductor, printed contact, land pattern, fiducial mark and more, enabling the standardization of PCBs that is in compliance with regulatory requirements that ensuring their safety and operability.
BS EN 62326-20 also provides users guidance on marking, packaging, and storage of printed circuit boards for printed circuit boards, facilitating the classification, storage, and usability in LED applications.
With obedience and compliance of BS EN 62326-20, users can develop and assess printed circuit boards for high brightness LEDs, ensuring operational stability, quality, and performance in electrical applications.
