Then, an electrical connection process is performed, and the first wire tip portion 222 is electrically connected to the bonding pad 264 of the chip 260 by a plurality of first wires 270 through a plurality of first wires 270, and a plurality of second wires 280 are passed through The second wire bonding tip portion 232 is electrically connected to the bonding pad 264 of the chip 260. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, please refer to Figure 3 and Figure 2B, and then perform a glue process. A mold 290 is used, and the mold 290 has a cavity 292. The chip 260 and the first wire tip 222, the second wire tip portion 232, the first wire 270, and the second wire 280 are placed in the cavity 292, and the mold 290 clamps the first guide leg 220 and the second guide leg 230, and is poured into a molten package. The material (not shown) is placed in the cavity 292, and then the steps of curing and removing the film are performed to obtain the structure as shown in FIG. 4. 9 degrees applies Chinese National Standard (CNS) A4 specifications (210 X 297 mm) 484223 6961twfdoc / 006 A7 B7 V. Description of the invention (s) Please refer to Figure 4 and Figure 4A, where Figure 4A shows the corresponding Figure 4 is a schematic plan view. A packaging material 204 covers the first wiring tip portion 222, the second wiring tip portion 232, the chip 260, the bonding pad 264, the first guide 270, and the table-first wire 280, and the packaging material 2Q4 exposes the first outer conductor. The leg portion 224 and the second outer guide leg portion 234. Then, a shear molding process is performed. The first outer guide leg portion 224 and the first outer guide leg portion 234 are pressed into a sea-shaped (gUii wing type) guide foot form or a] -shaped foot form by stamping. . In the above-mentioned configuration, in the lead frame of the present invention, the second wire-tip tip portion 232 of the second guide pin 230 can also be horizontally arranged and attached to the upper and lower sides of the active surface 262 of the chip 260, so It is allowable that the wire-tipped tip portions 222 and 232 of the higher-pin lead frame 210 are attached to the active surface 262 of the chip 260 and electrically connected to the bonding pad 264 thereof. Please refer to FIG. 4B, which is a schematic plan view corresponding to FIG. 4 according to the second preferred embodiment of the present invention. In the aforementioned first preferred embodiment, the second wire 280 is connected to the second wire tip portion 232. However, the present invention is not limited to the above-mentioned manner, and the second wire 280 can also be connected far from the second wire tip portion. The second guide pin 230 of the portion 232 and the second wire 280 also cross the second wire tip portion 232. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs -------------- install i-(Please read the note on the back first to write this page)-Line-In summary, the present invention The wafer has a guide pin structure and a process θ for laterally aligning and attaching the second wire tip portion of the second guide pin to the upper and lower sides of the active surface of the wafer, and it is perpendicular to the long opposite side, so Allows the higher-pin lead frame to be attached to the active surface of the chip and electrically connected to its pads. Therefore, the structure of the present invention is suitable for the paper size and applicable to China National Standard (CNS) A4 Specifications (210 X 297 mm) 484223 6961twfdoc / 006 A7 _B7_ V. Description of the invention (q) It will be applied to a chip with a high pin density and a higher pin position in the future. Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes and decorations without departing from the spirit and scope of the present invention. The protection scope of the present invention shall be determined by the scope of the attached patent application. -------------- Installation— (Please read the note on the back to write this page) Order: • Thread.
