Abstract
The invention discloses a plastic package lead frame which comprises a plurality of lead frame units in a single row. The lead frame units are connected through connection ribs, each lead frame unit comprises a base body and lead pins, the connection portions of the base bodies and the lead pins are bent, the lead pins are five in number and are distributed at equal intervals, each lead pin is provided with a radiating fin, each base body is provided with a boss, and positioning holes are arranged among the lead frame units. The lead frame is simple in structure, convenient to install, safe, reliable and low in production cost and saves materials.
Description
Technical field
The present invention 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.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of plastic packaging lead frame.
In order to solve the problems of the technologies described above, the invention provides a kind of plastic packaging lead frame, by a plurality of lead frames unit single composition, between each lead frame unit, by dowel, interconnect, lead frame unit comprises matrix and terminal pin, bend in matrix and terminal pin junction, described terminal pin is provided with five and equidistant arrangement.
As a further improvement on the present invention, described terminal pin is provided with fin.
As a further improvement on the present invention, described matrix is provided with boss.
As a further improvement on the present invention, between described lead frame unit, be provided with location hole.
Adopt said structure, its beneficial effect is: this lead frame structure is simple, is convenient to install, and terminal pin increases fin, avoids excess Temperature, and body portion is provided with a boss makes earth connection more reliable, saves material while producing simultaneously, reduces costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of plastic packaging lead frame of the present invention.
Fig. 2 is the body portion end view of plastic packaging lead frame of the present invention.
In figure: 1-lead frame unit, 2-matrix, 3-terminal pin, 4-fin, 5-boss, 6-location hole.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As illustrated in fig. 1 and 2, a kind of plastic packaging lead frame, by 1 single composition of a plurality of lead frames unit, between each lead frame unit 1, by dowel, interconnect, the width of lead frame unit 1 is 11.405 ± 0.025mm, lead frame unit 1 comprises matrix 2 and terminal pin 3, matrix 2 partial-lengths are 9.49 ± 0.1mm, thickness is 1.27 ± 0.015mm, the thickness of terminal pin 3 is 0.38 ± 0.01mm, bend in matrix 2 and terminal pin 3 junctions, make matrix 2 and terminal pin 3 planes at a distance of 2.67 ± 0.1mm, described terminal pin 3 is provided with five and equidistant arrangement, described terminal pin 3 is provided with fin 4, described matrix 2 is provided with boss 5, the height of described boss 5 is 0.38mm, between described lead frame unit 1, be provided with location hole 6, the diameter of location hole 6 is 1.52 ± 0.03mm.
This lead frame structure is simple, is convenient to install, safe and reliable, and production cost is lower simultaneously, saves material.
Within the similar designed lead frame of technical characterictic of any employing and the present invention will fall into protection scope of the present invention.
