The array type lead wire framework plate member is provided with two rows of circular positioning holes (2) which are transversely arranged. The array type lead wire framework plate member is also provided with multiple rows of circular positioning holes (3) which are vertically arranged and multiple rows of long waist-shaped holes (4) which are vertically arranged. One row of long waist-shaped holes (4) are arranged between two rows of circular positioning holes (3). Accurate positioning can be performed by the aforementioned array type lead wire framework plate member.
Description
Technical field
The utility model relates to semiconductor lead frame manufacturing technology field, is specifically a kind of array lead frame version part.
Background technology
Array lead frame version part 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.
The array lead frame version part of prior art is comprised of a plurality of single-pieces, is also provided with the circular location hole of many row's horizontally sets on described array lead frame version part.The array lead frame version part of said structure has the following disadvantages in actual use procedure: because the material of making array lead frame version part is very expensive, therefore for the object of saving material, need in limited version part, produce as much as possible more single-piece.But because this array lead frame version part quality is softer and version is only provided with the circular location hole of a plurality of horizontally sets on part, the location of pair array formula lead frame version part is more inaccurate, make array lead frame version part between each single-piece, can reserve larger space when making, thereby cause the waste of material.Therefore, from above description, can find out, the production cost of prior art array lead frame version part is higher.In addition, the body of the array lead frame version part of prior art is mainly comprised of copper base, therefore also makes its production cost higher.
Utility model content
The technical problems to be solved in the utility model is that a kind of array lead frame version part that can accurately locate is provided.
The technical solution of the utility model is, a kind of array lead frame version part is provided, and described array lead frame version part is comprised of a plurality of single-pieces; On described array lead frame version part, be also provided with the circular location hole of two row's horizontally sets; It is characterized in that: on described array lead frame version part, be also provided with the longitudinal circular location hole arranging of many rows and the longitudinal long waist-shaped hole arranging of many rows; Between the circular location hole of every two row, be provided with platoon leader's waist-shaped hole.
The two edges of described array lead frame version part are also provided with a plurality of limited impressions.
Described array lead frame version part is comprised of the silver coating setting gradually, copper base and silver coating.
Adopt after above structure, the utility model compared with prior art, has the following advantages:
On the utility model array lead frame version part, be also provided with the longitudinal circular location hole arranging of many rows and the longitudinal long waist-shaped hole arranging of many rows; Between the circular location hole of every two row, be provided with platoon leader's waist-shaped hole.The long waist-shaped hole that the circular location hole that circular location hole by two row's horizontally sets, many rows longitudinally arrange and many rows longitudinally arrange can pair array formula lead frame version part location very accurate, thereby make array lead frame version part between each single-piece, can reserve less space when making, thereby avoided the waste of material.Therefore, from above description, can find out, the production cost of the utility model array lead frame version part is lower.
As improvement, the two edges of described described array lead frame version part are also provided with a plurality of limited impressions.By a plurality of limited impressions, can further accurately limit the position of array lead frame version part, thereby avoid the waste of material to reduce production costs.
As improvement, described array lead frame version part is comprised of the silver coating setting gradually, copper base and silver coating.Array lead frame version part with prior art is compared, and the array lead frame version part of three layers of setting has reduced the application of copper material, has reduced production cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model array lead frame version part.
Shown in figure 1, single-piece, 2, the circular location hole of horizontally set, 3, the circular location hole that longitudinally arranges, 4, long waist-shaped hole, 5, limited impression.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of array lead frame of the utility model version part, described array lead frame version part is comprised of a plurality of single-pieces 1; On described array lead frame version part, be also provided with the circular location hole 2 of two row's horizontally sets; On described array lead frame version part, be also provided with the longitudinal circular location hole arranging 3 of many rows and the longitudinal long waist-shaped hole 4 arranging of many rows; Between the circular location hole 3 of every two row, be provided with platoon leader's waist-shaped hole 4.
The two edges of described array lead frame version part are also provided with a plurality of limited impressions 5.
Described array lead frame version part is comprised of the silver coating (not shown) setting gradually, copper base (not shown) and silver coating (not shown), and namely two surfaces of copper base are silver coating.
Below only with regard to most preferred embodiment of the present utility model, be described, but can not be interpreted as it is limitations on claims.The utility model is not limited only to above embodiment, and its concrete structure allows to change.In every case the various variations of doing in the protection range of the utility model independent claims are all in protection range of the present utility model.
Claims (3)
