Abstract
PURPOSE:To shut off radiation heat from a magnetic field generating coil, and to test a characteristic exactly, by providing a shutter on the notched part for coupling a magnetic bubble chip of a printed circuit substrate of a probe card. CONSTITUTION:On the upper surface of a printed circuit substrate 6 equipped with a testing probe 8, a shutter 7 is provided so as to oppose to its notches part. When coupling a magnetic bubble chip to be tested, the notched part is opened by drawing the shutter 7 in the direction as indicated with an arrow A, and the observation from the upper side can be executed. On the other hand, when testing a magnetic bubble chip, the notch part is closed by drawing the shutter 7 in the opposite direction of A, and radiation heat from a magnetic field generating coil is shut off. Accordingly, the characteristic is tested exactly.
