The discrete device is one of two branches of the semiconductor industry, is widely applied to the fields of consumer electronics, computers, peripheral equipment, network communication, automobile electronics, led display screens and the like, and mainly comprises a chip, a lead frame and a plastic package body. The existing lead frame, as shown in fig. 1, is provided with pins and a support, and the pins are provided with bonding pads for welding and fixing, and the bonding pads are only independently supported by a single pin, so that the bonding pads are easy to distort and deform in the actual production process, the welding process is unstable, and the production efficiency of discrete devices is affected.
Disclosure of Invention
The utility model aims to provide a lead frame of a discrete device, which solves the problem that a bonding pad is supported independently by a single pin and is easy to distort.
The embodiment of the utility model is realized by the following technical scheme: the lead frame of the discrete device comprises a bracket, wherein pins are arranged on the bracket, bonding pads are arranged on the pins, first connecting ribs are arranged between adjacent bonding pads, and second connecting ribs are arranged between the bonding pads and the bracket;
further, the first connecting ribs are in a straight shape;
further, the second connecting ribs are obliquely arranged;
further, a first groove is formed in the first connecting rib;
further, a second groove is formed at the joint of the second connecting rib and the bracket;
further, the first groove and the second groove are both V-shaped;
further, the widths of the first connecting ribs and the second connecting ribs are smaller than the widths of the pins.
The technical scheme of the utility model has at least the following advantages and beneficial effects: through the arrangement of the first connecting ribs, the stability between adjacent bonding pads can be enhanced; simultaneously, through the setting of second connection rib, can strengthen the stability between pad and the support, and then wholly promoted lead frame's pad's stability, avoided pad distortion, promoted pad welded stability, improved product quality.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples
The utility model provides a lead frame of a discrete device, as shown in fig. 2, which comprises a bracket 1, wherein a pin 2 is arranged on the bracket 1, a bonding pad 3 is arranged on the pin 2, a first connecting rib 4 is arranged between adjacent bonding pads 3, and a second connecting rib 5 is arranged between the bonding pad 3 and the bracket 1;
it should be noted that, by the arrangement of the first connecting ribs 4, the stability between the adjacent bonding pads 3 can be enhanced; simultaneously, through the setting of second connection rib 5, can strengthen the stability between pad 3 and the support 1, and then wholly promoted lead frame's pad 3's stability, avoided pad 3 distortion, promoted pad 3 welded stability, improved product quality.
The first connecting ribs 4 are in a straight shape and are arranged between the adjacent bonding pads 3, so that the stability between the bonding pads 3 can be enhanced; the second connecting rib 5 slope sets up between pad 3 and support 1, can strengthen the stability between pad 3 and the support 1, and the width of first connecting rib 4 and second connecting rib 5 is all less than the width of pin 2, for example, and the distance between the soldering leg sets up to 0.9mm, and pin 2 width sets up to 0.3mm, and the width of first connecting rib 4 and second connecting rib 5 all sets up to 0.2mm, when can improving stability, is convenient for process and has practiced thrift the cost.
The first groove 6 is arranged on the first connecting rib 4; the second recess 7 sets up in the junction of second connection rib 5 and support 1, and first recess 6 and second recess 7 are "V" style of calligraphy, and the setting of first recess 6 and second recess 7 can make things convenient for the blanking, and the too big body damage that leads to of strength when preventing simultaneously cutting the muscle has further promoted the stability of lead frame welding process, reduces the disqualification rate of product, has improved the benefit of enterprises.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
