[0034] SMD stands for Surface Mount Device, specifically surface mount devices.

[0035] DIP stands for Dual In-line Package, specifically referring to through-hole devices.

[0036] Research has shown that, please refer to [link / reference needed]. Figure 1 The original device 4 has straight pins 41 on both sides. In the process of fabricating traditional surface mount devices, the original device 4 needs to be bent first to form such a shape. Figure 2 The through-hole device 5 shown is a DIP series component. It involves bending the straight pin 41 into a straight-bent pin 51, and then flattening and bending the through-hole device 5 to form the shape shown. Figure 3 The surface mount device shown, namely the SMD series component, has S-shaped pins 31 for mounting formed on both sides of the component 3. However, the whole process requires two steps of molding, which results in high process cost and long production cycle.

[0037] Based on the above research, this disclosure provides a pin forming fixture and a surface mount device, which can directly form an S-shaped pin 31 from the straight pin 41 of the original device 4 in the frame plane state in one step, omitting the flattening process, saving process costs and reducing the production cycle.

[0038] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0060] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0061] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0062] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0063] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0064] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
