The present invention relates to a method for manufacturing a kind of multi-media card, and more particularly, to a manufacturing method capable of simultaneously achieving low cost, improving production rate, and improving product quality.                         

In recent years, advances in electronic integrated converter technology and materials have been made at a very high speed. The chip volume has been reduced to day, the function has been increased day by day, and the application range is widened. Therefore, products produced using electronic integrated converters are developing in lighter and smaller forms.

There are many different types of electronic dictionaries, digital cameras and various electronic products. With the development of chip sealing technology, the market has already sealed a single chip or multiple chips in a card of similar thickness to a thin card, and stores a large amount of electronic data in the chip. It forms a changeable memory, expands the functions of various electronic products, and makes an electronic medium for recording data. The combination of such a memory chip and a thin card is collectively referred to as a MultiMediaCard.

It is a storage medium that is widely applied to various electronic products because it is light and small in volume to meet the future development trend of electronic products. Illustrated in FIG. 1 is a manufacturing process diagram of a general multi-chip MMC that is currently used, and is divided into two types of manufacturing methods.

One is a thin card-shaped body part. In advance, one card outline is made of PVC or ABS material and the chip is planted in the required space. In addition, a special line of wire is designed in advance in one converter base plate, and a plurality of chips are planted in the converter base plate, and the conductors (gold wire or aluminum wire, etc.) are connected to each chip, and finally the chip sealing material It is then sealed in the converter base plate.

After the sealing is completed, the converter base plate is glued into the above-mentioned card outline and printed again on the card surface. However, from the experience of actual production, this current process is never ideal, and there is a lot of need for improvement.

    1. Difficult to speed up the production: The work of the card and the sealing of the chip is divided into two parts. In the current high-speed production environment of the electronics industry, this causes a relative weakening of competitiveness.

    2. The cost is high: The production order is not reduced because of the discontinuity of the production process, so the production cost is relatively high.

    3. The quality of the product is unstable: The chip is sealed on the converter base board with the colloidal sealing method, and it is difficult to control the quality of the joint in this process. .

    In order to improve the production process of MMC based on the spirit of pursuing more perfect technology and the technical experience in this field, the inventors experimented the possibility through several designs and actual tests and finally achieved the manufacturing method of the present invention. Became me.

In order to solve the above problems, the present invention provides a method of manufacturing a multi-media card, which is a kind of consistent continuous, high-speed multi-media card manufacturing method to improve the quality guarantee rate by controlling the product quality control. Its purpose is to.

The present invention for achieving the above object is a converter plate design step of designing a predetermined electronic track in a converter plate; A conductive piece bonding step of performing a surface bonding (SMT) operation of the conductive piece on the converter plate; A chip installation step of installing a plurality of chips in a specific position of the aforementioned converter plate; A wire connecting step of connecting the necessary wires (gold wire or aluminum wire) on each chip again; A chip sealing step of sealing a chip on the above-described converter plate as a sealing material and integrally molding the converter plate and the card material in which the chip is sealed to form a single thin card; A printing step of printing a character or a pattern on the surface of the card; And it provides a manufacturing method of a multi-media card, characterized in that it comprises a product completion step of finishing processing (packing, inspection of goods) for shipping the card through the printing process.

Hereinafter, the manufacturing method of the multi-media card according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a flow chart showing the manufacturing process of the present invention, the multi-media card, Figure 3 is a block showing a specific manufacturing process of the present invention, the multi-media card.
