Abstract
The utility model discloses a lead frame applied to a low-power electrical appliance. The lead frame is formed by connecting 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 base body and lead pins, a connecting part of the base body and the lead pin is bent, the lead pin is provided with a bonding area, the coining depth of the bonding area is 0.02-0.04mm, the number of the lead pins is three, and the lead frame unit is provided with positioning holes. Requirements for the bonding area coining depth of the lead pins at two sides of the frame are high, the two sides are symmetrical, the degree of processing difficulty is increased, but the additional value is high, thereby being widely applied to low-power high-precision electrical appliances, and playing an important role.
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 for low power electric appliance, by multiple lead frames unit single composition, each lead frame interconnects by dowel between unit, lead frame unit comprises matrix and terminal pin, bend in matrix and terminal pin junction, terminal pin is provided with bonding region, and the described bonding region pressure-sizing degree of depth is 0.02-0.04mm.
As further improvement of the utility model, described terminal pin is provided with three.
As further improvement of the utility model, described lead frame unit is provided with location hole.
Adopt said structure, its beneficial effect is: the bonding region pressure-sizing depth requirements of this framework both sides terminal pin is higher, both sides symmetry, and difficulty of processing coefficient increases, but added value is high, is widely used in, in low power high-accuracy electrical equipment, playing an important role.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model lead frame.
In figure: 1-lead frame unit, 2-matrix, 3-terminal pin, 4-bonding region, 5-location 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 for low power electric appliance, by 1 single composition of multiple lead frames unit, the width of lead frame unit 1 is 8.89 ± 0.025mm, between each lead frame unit 1, interconnect by dowel, lead frame unit 1 comprises matrix 2 and terminal pin 3, matrix 2 and terminal pin 3 thickness are 0.5 ± 0.01mm, bend in matrix 2 and terminal pin 3 junctions, make matrix 2 and terminal pin 3 planes at a distance of 1.27 ± 0.05mm, terminal pin 3 is provided with bonding region 4, the described bonding region 4 pressure-sizing degree of depth are 0.02-0.04mm, described terminal pin 3 is provided with three, terminal pin 3 width are 0.72 ± 0.02mm, described lead frame unit is provided with location hole 5, the diameter of location hole 5 is 1.55 ± 0.05mm.
The bonding region pressure-sizing depth requirements of this framework both sides terminal pin is higher, both sides symmetry, and difficulty of processing coefficient increases, but added value is high, is widely used in, in low power high-accuracy electrical equipment, playing an important role.
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.
