    Abstract - (Show below) - (Hide below)

    IEC 62326-20:2016 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 with those of ordinary PCBs, therefore, some aspects of this standard also describe general aspects. This edition includes the following significant technical changes with respect to the previous edition:
    a) this edition focuses on the technical content of the printed circuit board for high-brightness LEDs;
    b) the figures related to the printed circuit board for high-brightness LEDs have been refined.
