Abstract
Capacitor characteristics measurement apparatus and packing apparatus includes a turntable (1) intermittently driven at a constant pitch to supply capacitors (C) from a parts feeder (8) to a holder section (2) of the turntable (1) in a one-by-one manner. A capacitance measurement section (4) and an IR prediction section (5) are provided to determine whether each capacitor is acceptable or defective in quality based on the measured values obtainable from these sections (4, 5). The IR prediction section (5) applies a DC voltage to a capacitor while predicting the current value at termination of chargeup by use of its initial current value in the charge region of an insulation polarization component thereof upon application of the voltage thereto. A defective product ejection section (6) is provided for ejecting defective capacitors and an acceptable product extraction section (7) is provided for putting acceptable capacity into a storage section (31a) of a base material tape (31) conveyed by a taping device (30) and then packing the acceptable capacity by a process including a step of pasting a cover tape onto the base material tape (31).
