Abstract
The utility model discloses a lead frame capable of radiating heat quickly, which is formed by arranging a plurality of lead frame units in a single row, wherein the lead frame units are connected with each other through connecting ribs, the lead frame unit comprises a radiating fin and lead pins, a connecting part of the radiating fin and the lead pin is bent, the length of the radiating fin is 9.94+/-0.05mm, the width is 11.4+/-0.05mm, the number of the lead pins is three, and the radiating fin is provided with a circular hole. The lead frame disclosed by the utility model increases the specifications of the radiating fin, enables the radiating speed to be higher and the effect to be better, is suitable for operating in a high-temperature environment for a long time.
Description
Technical field
The utility model relates to a kind of lead frame.
Background technology
Lead frame is as the chip carrier of integrated circuit, it is a kind of electrical connection that realizes chip internal circuit exit and outer lead by means of bonding material (spun gold, aluminium wire, copper wire), form the key structure part of electric loop, it has played the function served as bridge being connected with outer lead, in the semiconductor integrated block of the overwhelming majority, all needing to use lead frame, is basic material important in electronics and information industry.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of lead frame.
In order to solve the problems of the technologies described above, the utility model provides a kind of lead frame of quick heat radiating, by multiple lead frames unit single composition, each lead frame interconnects by dowel between unit, lead frame unit comprises fin and terminal pin, bend in fin and terminal pin junction, fin length is 9.94 ± 0.05mm, and width is 11.4 ± 0.05mm.。
As further improvement of the utility model, described terminal pin is provided with three.
As further improvement of the utility model, described fin is provided with circular hole.
Adopt said structure, its beneficial effect is: this lead frame strengthens the specification of fin, makes radiating rate faster, and better effects if is suitablely worked for a long time in hot environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model lead frame.
In figure: 1-lead frame unit, 2-fin, 3-terminal pin, 4-circular hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, a kind of lead frame of quick heat radiating, by 1 single composition of multiple lead frames unit, the width of lead frame unit 1 is 11.405 ± 0.025mm, between each lead frame unit 1, interconnect by dowel, lead frame unit 1 comprises fin 2 and terminal pin 3, fin 2 thickness are 1.27 ± 0.015mm, terminal pin 3 thickness are 0.38 ± 0.01mm, bend in fin 2 and terminal pin 3 junctions, make fin 2 and terminal pin plane at a distance of 2.692 ± 0.15mm, fin 2 length are 9.94 ± 0.05mm, width is 11.4 ± 0.05mm, described terminal pin 3 is provided with three, described fin 2 is provided with circular hole 4, circular hole 4 diameters are 3.85 ± 0.05mm, this lead frame strengthens the specification of fin, make radiating rate faster, better effects if, suitablely in hot environment, work for a long time.
Within the similar designed lead frame of technical characterictic of any employing and the utility model will fall into protection range of the present utility model.
