Abstract (en)

[origin: EP1076345A2] A meandering inductor pattern (4) is formed on the upper surface of an insulating substrate (1). The inductor pattern (4) is formed by irradiating a conductor pattern (2) with a laser beam to form U-shaped trimming grooves (10) in the conductor pattern (2) in such a manner that two island-shape rectangular sections (3) are separated from the conductor pattern. <IMAGE>
