Abstract
PURPOSE: To prevent the defective product from being mixed into the nondefective products without selecting twice the products through measurement of the electrical properties, by detecting the defective product at the 1st measurement part and then exhausting it immediately and supplying only the nondefective products to the 2nd measurement part.
CONSTITUTION: The semiconductor device 11 drops by its empty weight along the supply chute 12 which is installed obliquely and then supplied to the measurement position A by the individual sending device 13 to receive the measurement and selection at the 1st measurement part 14 only for the quality. The switching shute 15 is provided at the position B under the part 14, and the semiconductor 11, if decided nondefective, is supplied to the 2nd measurement part 19 at the position C. In case the semiconductor is decided defective, it is exhausted to the defective product storing box 21. The semiconductor 11 supplied to the part 19 as a nondefective product undergoes a measurement of the electrical properties. According to the result of this measurement, the rotary chute 22 turns up to the fixed position to store the nondefective product into one of the boxes 23, 23'...n through selection. In such way, the double selection can be avoided, at the same time preventing the defective product from being mixed into the nondefective products.
