  • Printed circuit board and power supply device
    Patent number: 9788410
    Abstract: In the printed circuit board 100 in the power supply device, cover layers C1 and C2 are formed on a surface other than the connection areas 95A? and 95B? within a coil pattern EC, which corresponds to a surface-shaped exposure area exposed to the outside so that the size of the surface-shaped exposure area to which the conductive pattern E is exposed is adjusted, so that an effect, which restrains a conductor from being damaged, especially at a time of carrying the printed circuit board 100 while maintaining a heat radiating property of the conductor, is achieved.
    Type: Grant
    Filed: August 12, 2014
    Date of Patent: October 10, 2017
    Assignee: TDK CORPORATION
