Printed circuit board for e.g. cab interior control unit, has evacuation unit including cooling unit in shape of wings or plates extending laterally from each band or track portion and formed out of conducting material

摘要

The board (1) has a track or a band portion (3) made of electrically conducting material such as copper, aluminum, noble metal and alloy, where the portion of track or band presents a curved layout such as U shaped, and forming a calibrated or reference resistance. The track or band portion undergoes a rise in operation temperature, and is associated with a heat evacuation unit (4) of the board. The evacuation unit has a cooling unit in shape of wings or plates extending laterally from each of the band or track portion and formed in the conducting material.
