Abstract
The invention discloses an insertion and extraction band of a lead frame structure. The insertion and extraction band comprises a band-shaped insertion and extraction band body, wherein the band-shaped insertion and extraction band body is provided with a plurality of groups of parallel insertion and extraction openings, each insertion and extraction opening is provided with three insertion and extraction opening single structures, the three insertion and extraction opening single structures are arranged in parallel, the inner side of each insertion and extraction opening single structure is provided with an insertion groove, the width of each insertion groove is the same as the width of a pin of the lead frame structure, and then the pin of the lead frame structure is connected with each insertion groove. The insertion and extraction band of the lead frame structure, provided by the invention, has the advantage that the pin of the lead frame structure does not need to be cut off, the pin with a proper size can be directly inserted and extracted, and the insertion and extraction band body can be repetitively used, so the material is saved.
Description
Technical field
The present invention relates to the semi-conductor discrete device sealed in unit, particularly save the lead frame structure plug band of consumptive material.
Background technology
Lead frame structure plug band commonly used, its section has 3-4 altogether, wherein having 2 existing lead frame accepted standards in the part of fin all is general international standard, it is three-star standard, the area of the section in the middle part of fin is 3mm*3mm, so often need larger shear force in its cut-out operation process, and this also increases the ohmic contact of chip with regard to having caused the impact endurance test shock in the cutting-off process.
For this technical problem, the beautiful keemun of Wuxi City Photoelectron Corp. has applied for that on August 31st, 2011 a kind of name is called: scissile lead frame structure, application number is: 201120002290.The technical scheme of this patent discloses the agent structure of lead frame structure, and namely its bottom legs need to be blocked.Because the lead frame structure consumption is very large, blocking the pin that gets off just becomes waste wood, has not had use value, the waste that has caused material to hinder.
Summary of the invention
For the pin of the lead frame structure that solves prior art need to block, cause the problem of waste of material, the invention provides a kind of lead frame structure plug band.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of lead frame structure plug band comprises banded plug band body, on described banded plug band body side by side be provided with some groups of plug-and-pull ports.
Each group plug-and-pull port has three plug-and-pull port monomer structures, and three described plug-and-pull port monomer structures are arranged side by side.
Be provided with slot in the described plug-and-pull port monomer structure, the width of described slot equates with the width of the pin of lead frame structure, so that the pin of described lead frame structure is connected with slot.
Lead frame structure provided by the invention plug band can make the pin of lead frame structure not need to do again and block, as long as the size of pin is carried out, directly plug is used, and the plug band body can repeated multiple timesly use, and reaches the effect of saving consumptive material.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of the described lead frame structure plug of embodiment of the invention band.
Embodiment
As shown in Figure 1, the described lead frame structure of embodiment of the invention plug band comprises banded plug band body 1, on described banded plug band body 1 side by side be provided with some groups of plug-and-pull ports.
Each group plug-and-pull port has three plug-and-pull port monomer structures 2, and three described plug-and-pull port monomer structures 2 are arranged side by side.
Be provided with slot in the described plug-and-pull port monomer structure 2, the width of described slot equates with the width of the pin of lead frame structure 3, so that the pin of described lead frame structure is connected with slot.
Lead frame structure provided by the invention plug band can make the pin of lead frame structure not need to do again and block, as long as the size of pin is carried out, directly plug is used, and the plug band body can repeated multiple timesly use, and reaches the effect of saving consumptive material.
Claims (3)
