Description of the new type: [Technical field to which the new type belongs] This creation relates to a structure that can stably carry a wafer, especially a chip that can be stably combined with a lead frame, and the lead frame can prevent solder group A from causing a short circuit when used. The chip composition structure is improved. [Prior art] As shown in the sixth figure, the conventional chip package structure has a conductive lead frame 10, and the lead frame 10 is formed by punching out a plurality of chip leads 101 on both sides or around it. A bump 102 is provided at the lower end of each pin 101, and an end surface 103 of the bump 102 is used as a conductive part, and an adhesive tape 20 is attached above the lead 101 of the lead frame 10, and the tape 20 A semiconductor wafer 30 is fixed. If so, an electrically connected metal wire 40 is provided between the wafer 30 and each of the pins 101, and after the metal wire 40 is connected, an insulating sealing compound 50 is implemented. The periphery of the chip 30 and the bottom surface of the lead frame 10 are sealed, and only the lower end surface 103 of the pin 101 is reserved to be exposed, and the circuit board is assembled to form an electrical connection. The conventional chip packaging structure disclosed above is a commonly used packaging technology. However, the actual use of today's chips ± often does not require the insulating sealing compound 50 described above, which can be achieved by other protection devices or heat sinks. Sticking, that is to achieve the effect of protecting the wafer, but simply does not implement the sealant 50, the instability of the sheet 30 is fixed to the lead frame 10 only by the tape 20, and the tape 20 is specially manufactured Articles, which are expensive and reduce the cost of chip packaging; In addition, the conductive end faces 103 opened by the pins 101 and the bottom bumps 102 are opened, even if the implementation becomes a staggered position structure. At the same plane, when solder is used to assemble the lightning contacts on the circuit board, short situations such as solder overflow contacting other conductive end faces 103 are still prone to result in more quality control costs such as subsequent repair work. And M266542 [New content] The main purpose of this creation is to propose a stable structure of the wafer structure. In particular, the lead frame is used to form a stable assembly of the wafer and the wire frame. Make sure to prevent the short circuit protection effect when the solder is assembled and used. According to the above purpose, the content of this creative implementation is composed of a single crystal, in which: the chip of the Diaochen wood is a conventional semiconductor wafer; the lead frame is a two-row or matrix arrangement with multiple conductive pins side by side. The structure is selected to be provided with an insulating fixing seat on the lead frame (each lead), so that the fixing seat is fixed to each pin, and an insulating stopper is provided on the lower end surface of each pin of the lead frame. Positions of the stoppers of the pins are set separately, ^ external conductive parts are formed at the lower end surfaces of the pins, which are staggered from each other; thereby, the fixed structure can be used to stably carry the wafer composition structure of the assembled wafer, so it is not necessary to use The packaging cost of the expensive tape is reduced, and the stopper has a protective effect to prevent solder overflow. [Embodiment] The following describes the structural features and other functions and purposes of the creation in detail according to the embodiments of the drawings: As shown in the drawing, the creation is a "stable structure of the wafer", which is about semiconductor wafers The improvement of the package structure mainly includes a y βθ sheet 1 and a lead frame 2, and after the composition, an electrically conductive metal wire 3 and a sealing gel 4 for protecting the metal wire 3 are implemented, of which: 1. It is an article made of conventional technology, that is, a sheet-shaped electronic component usually made of semiconductor materials, so its detailed composition, technology, and functions are not described in detail; M266542 lead frame 2 is provided with a plurality of The conductive elements 21 are arranged side by side in two rows (as shown in the second figure) or in a matrix arrangement (as shown in the fifth figure). The conductive elements 21 can be formed by stamping metal sheets, but they are selected on the lead frame 2. (That is, on each pin 21) is provided with an insulating fixing base 22, so that the fixing base is fixed on each pin 21, and an insulating stopper is protruded at a selected position on the lower end surface of each pin 21 of the lead frame 2. 23, borrow The stopper 23 convexly arranged at the lower end of the pin 21 is arranged in a positional structure, so that the outer end of each pin 21 is formed with an external conductive portion 2 4 arranged in a mutually offset position; by this, please refer to the first figure As shown, the fixing base 22 above the lead frame 2 is used for mounting and fixing on the chip 1 (the fixing method is described later), and is connected to the electrical contacts of the chip 1 and selected parts of each pin 21 respectively. There is a metal wire 3, and a sealing compound 4 constituting a sealing and protecting the metal wire 3 and its contact point can be selectively implemented at the position where the metal wire 3 is set. As mentioned above, the lead frame 2 of the present invention is implemented with an insulating fixing base 22, and its form includes, as shown in the third and fourth figures, two or more rows of pins 21 arranged in a row. The above-mentioned fixed base 22 is injection-molded, so that the wafers 1 can be collectively used. ^ The outer sides of each fixed base 22 can be convex δ and a supporting wall 25, so that the wafer operator can accurately align and facilitate positioning. As mentioned above, the wafer 1 is assembled with the fixing base 22 of the lead frame 2. The embodiment includes: the liquid crystal can be adhered to the crystal by the fixing base 22 during injection molding to fix the wafer after the fixing base 22 is solidified and shaped. 1 structure; and includes a solid holder 22 that can be formed on the lead frame 2 in advance, and then use other sticky material holders 22 to achieve the chip! Fixed assembly of the packaging knot i This creation can be stably carried a έέ + sheep? m ^ Silk structure is improved. Due to the guide j ′, the chip 1 is precisely aligned and the mounting seat 2 7 M266542 structure is stable, it can be selectively implemented on the periphery of the chip when the shirt is applied. 'Or don't have to implement wafers! The outer sealing gel can be applied by other protective f or heat sinks. The fixed seat has the function of stably protecting the chip 1, for example, it can prevent the sealing gel from ejecting the molding force, or other The friction force of the protection device or the heat sink when the wafer is damaged 1 '. Secondly, the implementation of this fixed seat 22 has the function of directly = the wafer 1', and its material cost is more than that of the wafer bonding adhesive f. Low, so it can reduce chip packaging costs. The other 3 of Lu 2 are: 1 is created at the lower end of each pin 21 of the lead frame 2: the external conductive portion arranged with pins 21 at mutually offset positions == the external conductive portion 24 and the circuit board When other items are assembled, the assembly of tin 3 and electrical connection can prevent the short-circuit effect by the stopper 23 to prevent short-circuit effects, which can result in production in assembly applications. Reduced mouth defect rate ’saves quality control costs such as repair. To sum up, 'this creation' can be stably carried is indeed practical and creative, and the complex hand $, ',, Όstructor' has already functioned-the use of leaf eyebrows stir-fry is also novel and undoubted, and ^ text The purpose of K is less consistent, and it has been said that the Reasonable Progress Law filed a new patent application, but I would like to pray for the benefit, and I feel that it is morally convenient. … The moon fishing bureau will review it in detail, and give it to Zhunzhuan 8 M266542 [Simplified illustration of the drawing] 2 * This is a cross-sectional schematic diagram of the composition structure of the creative chip. : This is a schematic diagram of the bottom surface of the composition structure of the creative chip.
