Abstract
The utility model discloses a double-row lead frame. The characteristics are that the double-row lead frame is formed by butting two rows of identical lead frames, the lead frame is formed by lead frame units, the head portions of the lead frame units are connected with each other at an interval of four lead frame units, the lead frame unit comprises a substrate and lead pins and provided with positioning holes. The lead frame is produced by adopting a double-row mode in the whole manufacturing process, the head portions are arranged at the middle oppositely, thereby avoiding a circumstance that the head portions are damaged in delivering process when arranged outside, the a group of the head portions are connected at the inverter of four lead frame units, and the difficult in separating the two rows finally.
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 double lead frame.
In order to solve the problems of the technologies described above, the utility model provides a kind of double lead frame, and the lead frame docking identical by two rows forms, and described lead frame is comprised of lead frame unit, wherein, every four lead frame unit, relative lead frame unit header is connected to each other.
As further improvement of the utility model, described lead frame unit comprises matrix and terminal pin.
As further improvement of the utility model, described lead frame unit is provided with location hole.
The double lead frame of the utility model meets package requirements, in whole manufacturing process, adopt double mode to produce, in the middle of head comes relatively, avoid head to come outside and transmitted the situation that in rules, head is damaged, every five lead frame unit, wherein one group of head is connected, the difficulty while having reduced final double separating.
Accompanying drawing explanation
Fig. 1 is the structural representation of the double lead frame of the utility model.
In figure: 1-lead frame, 2-lead frame unit, 3-matrix, 4-terminal pin, 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 double lead frame, it is characterized in that: lead frame 1 docking identical by two rows forms, described lead frame 1 is comprised of lead frame unit 2, wherein every four lead frame unit 2, relative lead frame unit 2 heads are connected to each other, and described lead frame unit 2 comprises matrix 3 and terminal pin 4, and described lead frame unit 2 is provided with location hole 5.
The double lead frame of the utility model meets package requirements, in whole manufacturing process, adopt double mode to produce, in the middle of head comes relatively, avoid head to come outside and transmitted the situation that in rules, head is damaged, every five lead frame unit, wherein one group of head is connected, the difficulty while having reduced final double separating.
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.
