Description
Technical field
The utility model is related to leadframe technologies field, specially a kind of preferable lead frame of radiating effect.
Background technology
In recent years, domestic semiconductor is quickly grown, and the encapsulation amount of particularly discrete device is very big, and technical requirements are got over
Come higher, but existing equipment all has certain defect, such as radiating effect is not good enough, cause service life of equipment compared with
It is short, and reliability is relatively poor, because pressure-sizing area is one, causes processing efficiency low, wastes raw material, competitiveness is low
Under.
Utility model content
The purpose of this utility model is to provide a kind of preferable lead frame of radiating effect, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of preferable lead frame of radiating effect,
Including frame body, terminal pin part, pressure-sizing area and fin, the left and right sides of the frame body is provided with flute profile impressing, described
It is provided with frame body on matrix, and matrix and is provided with positioning hole, fin and terminal pin part, the terminal pin part is by more
Individual terminal pin unit composition, and be provided with terminal pin unit at the top of three terminal pins, the terminal pin part and be provided with essence
Nip.
It is preferred that, the pressure-sizing area is to be coated with electrodeposited coating on two, and pressure-sizing area.
It is preferred that, the length of the fin is 17.50mm.
Compared with prior art, the beneficial effects of the utility model are：The equipment is two by pressure-sizing area, and pressure-sizing area
On be coated with electrodeposited coating, improve production efficiency, saved raw material, reduce production cost, improve competitiveness, fin
Length is 17.50mm, makes radiating effect more preferably, service life is longer, it is ensured that the reliability of equipment, by a left side for frame body
Right both sides are provided with flute profile impressing, on the one hand add the adhesion of plastic packaging resinite and frame body, on the other hand effectively prevent
Electric metal plate liquid penetrates into the failure that inside parts cause part during electric metal plate, substantially increases yield rate and reliability, and structure
Simply, it is reasonable in design.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, Fig. 2 and Fig. 3, a kind of embodiment that the utility model is provided：A kind of preferable lead of radiating effect
Framework, including frame body 7, terminal pin part 5, pressure-sizing area 2 and fin 8, the left and right sides of frame body 7 are provided with flute profile impressing
9, it is provided with matrix 1, and matrix 1 on frame body 7 and is provided with positioning hole 6, fin 8 and terminal pin part 5, terminal pin part
5 are made up of multiple terminal pin units 3, and three terminal pins 4 are provided with terminal pin unit 3, and the top of stitch part 5 is provided with
Pressure-sizing area 2, pressure-sizing area 2 is that electrodeposited coating is coated with two, and pressure-sizing area 2, and the length of fin 8 is 17.50mm.
Operation principle；In use, will be attached by dowel between frame body 7, the left and right sides of frame body 7 is set
There is flute profile to imprint 9, on the one hand add the adhesion of plastic packaging resinite and frame body 7, on the other hand effectively prevent electric metal plate process
Middle electric metal plate liquid penetrates into the failure that inside parts cause part, substantially increases yield rate and reliability, and pressure-sizing area 2 is two
It is individual, and electrodeposited coating is coated with pressure-sizing area 2, production efficiency is improved, raw material have been saved, production cost is reduced, improved competing
Power is striven, the length of fin 8 is 17.50mm, make radiating effect more preferably, service life is longer, it is ensured that the reliability of equipment, and
It is simple in construction, it is reasonable in design.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, can realize that this practicality is new in other specific forms
