2. Description of the Related Art FIG. 3 is a plan view showing an example of a conventional arrangement of bonding pads on a first substrate 7. The first substrate 7 has a rectangular shape, and a square ring-shaped second substrate 8 is arranged so as to surround it. Bonding pads are formed along the left side and the right side of the first substrate 7 due to the influence of the wiring pattern in the substrate, etc., and the second bonding pad is formed at the nearest position corresponding to this bonding pad. Bonding pads on the substrate 8 are formed. Wire bonding is then performed between the nearest bonding pads of the first substrate 7 and the second substrate 8.

According to this example, for example, after performing bonding with the bonding pad 10 on the left side of the substrate,
After the first substrate and the second substrate are moved to the left side, the bonding pad 9 on the right side has to be bonded, so that unnecessary time other than the bonding is required for moving the two substrates. If the precision of the movement of the substrate is not high, the bonding tool will be displaced from the center of the bonding pad on the right side of the substrate. further,
In normal wire bonding, the order of bonding is decided, for example, first bonding is performed on the first substrate and then second bonding is performed on the second substrate. The substrate or the bonding tool must be moved, while the bonding pad on the right side of the substrate must be moved from the left to the right.

As described above, in the prior art, unnecessary time other than the time required for wire bonding is wasted. In order to perform bonding on the right side after bonding on the left side of the substrate, the substrate or bonding tool must be moved.
The moving accuracy must be high enough. Furthermore, since the bonding on the right side is opposite to the bonding direction on the left side of the substrate, it is necessary to devise it.

[Operation] A plurality of bonding pads on the first substrate
By arranging the substrates at equal intervals along only one side of the substrate, it is not necessary to move the substrate largely, so that the accuracy of the movement is not required so much, and the wasted time can be eliminated to shorten the bonding time. Further, since the direction from the first bonding to the second bonding is the same for all bonding pads, no special operation such as rotating the substrate or the bonding tool is required.

FIG. 1 is a plan view showing an embodiment of the present invention. Reference numeral 1 is a rectangular first substrate, and 2 is a ring-shaped second substrate arranged so as to surround the first substrate. On the first substrate 1, all the bonding pads 3 are arranged at equal intervals along the lower side. Further, a bonding pad for second bonding is arranged at a position closest to the second substrate corresponding to each bonding pad of the first substrate.

By arranging the bonding pads in this way, the movement of the substrate or the bonding tool is minimized in order to bond all the bonding pads, and the time required for the bonding is eliminated. Furthermore, the direction of the second boarding for the first bonding is only from the top to the bottom in the drawing for all wire bondings. According to the present invention,
If all the bonding pads are arranged along one side of the substrate, bonding can be performed in a minimum time, and the movement of the substrate and the bonding tool is also minimized. Therefore, the accuracy of the movement need not be so high. . Furthermore, since the direction from the first bonding to the second bonding is the same in all bondings, it is not necessary to rotate the substrate or the bonding tool. Needless to say, the shape of the second substrate is not limited to the square donut shape shown in the embodiment.

Next, another embodiment will be described with reference to FIG. This embodiment is an example in which the electrical connection from the substrate to the external circuit relies on a mounting tape rather than metal wire bonding. Four
Is a first substrate, and as shown by 5, terminal patterns for mounting are formed at equal intervals along the lower side of the substrate. On the other hand, 6 is a mounting tape, and mounting terminals are provided at the same pitch as the terminal pattern of the substrate 4. By electrically connecting the mounting terminal on the substrate side and the mounting terminal on the tape by soldering, anisotropic conductive adhesive or the like, electrical connection of the circuit in the substrate to the outside is achieved. In this case, if a plurality of mounting terminals in the board are formed along one side of the board, the tape shape is simple and the size is the minimum necessary. Further, when the terminals of the substrate and the tape are joined, since the terminals are arranged in a line at one place, the shape of the solder heating jig or the anisotropic conductive adhesive crimping jig can be simplified. . Also, the mounting terminal is 1
The reliability of the mounting part is also high because they are arranged in one place.

According to the present invention, the time required for bonding can be minimized, and the accuracy of movement of the bonding apparatus is not required, and the operation such as rotation is not required. Furthermore, since the bonding area is narrowed, it can be expected that the reliability of bonding will be greatly improved. Further, even when the mounting tape is directly bonded to the substrate, the device for bonding can be simplified and the reliability of the bonded portion can be improved, and the same effects as in the case of wire bonding can be expected.
