<p>The circuit board comprises an insulating board (2) of insulating material and an electric circuit formed of etched copper layers (3,4) provided on the outer surfaces of it. A shorting bar (5) as a high-current conductor is placed, through a burring process, on the copper layer (3) which conduct large amounts of current, and an electric component is placed on the burred portion and screwed fixedly with a bolt (7).</p> |
