Abstract

PURPOSE:To enable storage of packages irrespective of the kinds thereof and, besides, to conduct efficiently discrimination of good and bad products and sorting storage thereof. CONSTITUTION:In a half-finished lead frame mo whereon a plurality of semiconductor chips 32 are mounted and wherein each of the chips is sealed with resin, a bad product discrimination mark NG is given to a bad product. Semiconductor products (m) are separated discretely by a lead forming device 34. Each product is transferred onto an intermediate stage 44 by a traverser 42 and the presence or absence of the bad product discrimination mark NG is discriminated by a bad product discrimination mark discriminating device 46. While the semiconductor products (m) are conveyed to a good product storage pallet 48 by a single robot hand 50, the product having the bad product discrimination mark NG is dropped for exclusion into a bad product receiving box 52 in the course of a route of conveyance.

(actual tube). The number of semiconductor products m stored in the semiconductor product storage tube 8 is counted by counting the number of shots. When this count reaches a predetermined value indicating that one of the real tubes 8 is full, the cylinder 7 is driven, the tube receiving shuttle 6 slides along the rail 4, and the empty tube 8 is stored accordingly. The real tube 8 moves to the standby location. The two real tubes 8 that have been moved to the standby location are removed from the tube receiving shuttle 6, and empty tubes are newly set. A new semiconductor product m is stored in the empty tube 8 that has been moved to the storage location. In this device, all semiconductor products m are once stored in the semiconductor product storage tube 8 without distinguishing between good products and defective products. Discrimination between good and defective products is performed in a separate process, and when a defective product is found, all semiconductor products are removed from the semiconductor product storage tube 8.
After removing the defective items, store them again.

[B] Another device for separately accommodating non-defective products and defective products is disclosed in Japanese Utility Model Application Publication No. 2-25853 (however, illustration is omitted). In this device, semiconductor products discharged from a semiconductor product storage tube are sent one by one to a measuring section using a conveyor belt. The measurement unit determines the bent state of the leads of the semiconductor product through image processing. If the bent condition is normal, the same conveyor belt sends the product to a tube for storing non-defective products and stores it. If the bent state is out of specification, it is picked up and held by a robot hand for rejecting defective products, and discharged into a storage box placed on the side of the conveyor belt.

[Operation] In the method for molding, sorting, and storing semiconductor products of the present invention, the initial target component is a frame-shaped component that integrally includes a plurality of semiconductor chips. That is, it is a semi-finished lead frame in which a plurality of semiconductor chips are mounted on a lead frame, each chip is sealed with resin, and lead molding is performed. Even if a defective chip is discovered at this semi-finished lead frame stage or at an earlier stage, the defective chip cannot be immediately removed from the semi-finished lead frame on the spot. Therefore, defective chips are marked in advance with defective product identification marks. Then, the semi-finished lead frame is separated into chips and sequentially sent out as semiconductor products.

Instead of arranging these individual semiconductor products on a pallet as in the conventional device [A], and without performing electrical measurements that require complicated operations, the process of sending out the individual semiconductor products sequentially is performed. The presence or absence of a defective product identification mark is simply determined. All semiconductor products, regardless of whether they have a defective product identification mark or not, are sent to the good product storage pallet. The items that fall are removed during the transport route to the non-defective storage pallet. Semiconductor products without defective product identification marks are sent to the non-defective product storage pallet where they are arranged and stored.

[0023] Since a pallet is used as a storage unit,
Semiconductor products in many types of packages can be stored regardless of the type of package. What is particularly important is to remove defective products from falling during the transport route to the pallet. That is, unlike the conventional device [A], defective products are not stored beyond the good product storage pallet. Also, defective products are not arranged and stored on pallets. Since defective products are simply removed during the transport route, defective products can be handled very efficiently.

The lead forming apparatus separates this semi-finished lead frame into chips and sends them out as semiconductor products. The traverser transfers the semiconductor products one by one to the intermediate stage. At the intermediate stage, the semiconductor product is positioned and held, and the presence or absence of a defective product identification mark is identified by a defective product identification mark identification device. The robot hand transports non-defective semiconductor products from the intermediate stage to the non-defective product storage pallet and stores them in two-dimensional alignment. However, if the semiconductor products being transported are defective, the transport path The defective products are removed into a receiving box set up along the way.

This semiconductor product molding/sorting/storage device is configured to realize the above-described molding/sorting/storage method, but is particularly designed to remove defective semiconductor products by dropping them into a defective product receiving box. Another feature is that the single robot hand that transports non-defective semiconductor products to a non-defective product storage pallet also picks up and transports defective semiconductor products, and drops them into a defective product receiving box during the transport route for removal. In other words, since a single robot hand has both the functions of transporting good products and removing defective products from falling, operational efficiency is high.

[Effects of the Invention] As explained above, according to the method for molding, sorting and storing semiconductor products of the present invention, defective products are marked with a defective product identification mark before being separated into individual semiconductor products from a semi-finished lead frame. After separation, the presence or absence of a defective product identification mark is determined. If there is no defective product identification mark, the product is sent to a good product storage pallet and stored in alignment, but if a defective product identification mark is present, the transport route to the nondefective product storage pallet is determined. Since the falling parts are removed during the process, defective products can be disposed of very efficiently. Furthermore, since a pallet is used as a storage section for good products, many types of semiconductor products can be stored regardless of the type of package.
