With reference to the accompanying drawing to lead frame provided by the utility model and using the lead frame packaging body it is specific
Embodiment elaborates.
Fig. 1 is the structural schematic diagram of one embodiment of the utility model lead frame, and Fig. 2 is that the structure of frame unit is shown
It is intended to.Fig. 1 and Fig. 2 is please referred to, the utility model lead frame includes multiple frame units 1.Pass through between the frame unit 1
The connection of one outline border 2.Four frame units 1 are schematically painted in Fig. 1.The frame unit 1 is defined by a packaging line W, phase
It is a Cutting Road between adjacent frame unit 1.That is, the region that packaging line W circle shows is the region of frame unit 1.
The frame unit 1 has at least one to connect muscle 10.In the present embodiment, there are two connect muscle to the tool of frame unit 1
10, and two company's muscle 10 are symmetrical arranged, in other embodiments, the frame unit 1 may include company's muscle 10 or more
A even muscle 10.The even muscle 10 is extended to from the packaging line W outside the packaging line W, and at the Cutting Road, the company
Muscle 10 is connect with the outline border 2.
There is an at least fixation hole 11 on the even muscle 10 in the packaging line W.I.e. in the frame unit 1
There is an at least fixation hole 11 on company's muscle 10 in region.In subsequent encapsulation, the fixation hole 11 is can be filled in plastic packaging material, thus
Enhance the fixed function of lead frame and plastic packaging material.
On the direction towards the outline border 2, the width gradual change of the fixation hole 11.Specifically, from the frame list
On the center to the direction of the outside of the frame unit 1 of member 1, the width of the fixation hole 11 is gradually increased or gradually subtracts
It is small, it is formed and bores shape hole.For example, in the present embodiment, as shown in Fig. 2, on the direction towards the outline border 2 (i.e. in X-direction),
The width of the fixation hole 11 is gradually increased；In a second embodiment, as shown in figure 3, on the direction towards the outline border 2
The width of (i.e. in X-direction), the fixation hole 11 is gradually reduced.
The advantages of width gradual change of the fixation hole 11, is: one, can be under the premise of with good fixed function
Metal reduction on the company's of reducing to the greatest extent muscle, in order to avoid influence its supporting role, two, after the lead frame forms packaging body,
It can play the role of deformation sustained release transition when being cut, improve the reliability of encapsulation.
Please continue to refer to Fig. 1, in the present embodiment, the frame unit 1 further includes a base island 12, in the packaging line W
Interior, the even muscle 10 is connect with the base island 12.Specifically, one end of the even muscle 10 is connect with the base island 12, it is another
End is connect with the outline border 2.Wherein, on the inside of the packaging line W, at least one is additionally provided with from the company on the even muscle 10
The blend stop 13 of 10 side of muscle protrusion, the blend stop 13 further can play fixed function to plastic packaging material.
Fig. 4 is the structural schematic diagram of the 3rd embodiment of frame unit.Referring to Fig. 4, the present embodiment and first embodiment
Difference be, it is described that even there is on muscle 10 one first fixation hole 110 and one second fixation hole 111, towards the outline border 2
On direction, first fixation hole 110 and second fixation hole 111 are arranged successively.That is, in the present embodiment, institute
There are two fixation holes for tool on the company's of stating muscle 10.
The width of first fixation hole 110 is gradually increased, and can alleviate the shape between base island 12 and the even muscle 10
The width of varying stress, second fixation hole 111 is gradually reduced, and can alleviate the deformation between outline border 2 and the even muscle 10
Stress draws the intensity pullled, and then provides the package reliability of subsequent packaging body when reducing packaging body cutting.
Further, in the third embodiment, the length of first fixation hole 110 is less than second fixation hole 111
Length, can be in the work for guaranteeing to play deformation sustained release transition when further cutting under the premise of providing good support strength
With improving the reliability of encapsulation.
The present invention also provides a kind of packaging body, the packaging body is using above-mentioned lead frame as support frame.Fig. 5 is envelope
Fill the structural schematic diagram of body.Referring to figure 1, figure 2 and figure 5., the utility model packaging body includes above-mentioned lead frame and a modeling
Seal the plastic-sealed body 3 of the lead frame.Specifically, cut after plastic packaging material coats the lead frame along the packaging line W,
Form the packaging body.The even muscle 10 is from 3 internal stretch of plastic-sealed body to the side of the plastic-sealed body 3, and the even muscle
10 end face is exposed to the side of the plastic-sealed body 3.The plastic-sealed body 3 fills the fixation hole 11, then fixation hole 11 into one
Step enhances the binding force of the plastic-sealed body 3 and the lead frame.In addition, on the direction towards outside the plastic-sealed body 3,
The width gradual change of the fixation hole 11, can alleviate stress when cutting, to avoid the plastic-sealed body 3 and lead frame point
Layer.
