Description
Technical field
The utility model relates to technical field of semiconductor encapsulation more particularly to the structure of novel rectangular frame to improve.
Background technique
Currently, common rectangular frame is mostly connected by dowel with sideband by single rectangular frame in the market, due to square
Shape frame raw material and energy cost are very high, and existing rectangular frame needs leg of frame band up and down, cause material consumption high, and drop
Low production efficiency；The utilization rate of copper material is seriously affected, as shown in Figure 5.
Utility model content
The utility model is in view of the above problems, provide a kind of compact-sized reasonable, the high novel rectangular of copper material utilization rate
Frame.
The technical solution of the utility model is: including sideband one, sideband two and several monomeric units；Several monomer lists
Prolong vertical direction arrangement setting between member, and is parallel to each other；
The sideband one is fixedly connected on the side of several monomeric units；The sideband two is fixedly connected on several institutes
State the other side of monomeric unit；
Several monomeric units include several monomers for prolonging horizontal direction and uniformly arranging；Close to top position on the monomer
A pair of symmetrically arranged dowel one is installed；A pair of symmetrically arranged dowel is equipped with close to bottom position on the monomer
Two；
Pass through several longitudinally connected muscle connections uniformly arranged between several vertically arranged monomeric units.
Four monomers are one group；The longitudinally connected muscle is between group and group.
Two monomers are one group；The longitudinally connected muscle is between group and group.
The thickness of the dowel one is incremented by successively by the laterally outside close to the monomer.
The thickness of the dowel two is incremented by successively by the laterally outside close to the monomer.
For the utility model in the material of semiconductor packages, frame is wherein critically important one.Available frame design, greatly
Part seriously affects the utilization rate of copper material as shown in figure 5, the edge grinding in existing design is excessive for matrix arrangement.According to this frame
Set up meter to calculate, the product number in every square millimeter of area are as follows: 80/(76.1*48.8)=0.02154.The utility model product
Effective material part design needed for itself is constant, and by effective material part of product, even muscle is set the insertion of a portion position
Part is counted, as a part of even muscle, thus the largely waste of the company's of reduction muscle design.According to new design scheme, calculate
To the product number in every square millimeter of area are as follows: 80/(76.1*42.4)=0.02479, than former scheme unit area product number
Amount increases by 15%, effectively improves material effective rate of utilization, reduces waste of material.
The utility model also uses matrix form to design, and devises necessary even muscle, in the production process of semicon industry
In, the processes such as welding, plastic packaging, rib cutting can be normally carried out, and old scheme operation mode indifference, but efficiently use area substantially
It is promoted.In addition to material economy, in each process production process, in unit area mold pressing process, the machinable quantity of single
It obviously increases, therefore the more former scheme of efficiency of each process is obviously improved.
In conclusion the utility model has the features such as compact-sized, to reduce material loss, improve productivity.

Specific embodiment
The utility model is as shown in Figs. 1-5, including sideband 1, sideband 22 and several monomeric units 3；Several monomers
Prolong vertical direction arrangement setting between unit 3, and is parallel to each other；
The sideband 1 is fixedly connected on the side of several monomeric units 3；If the sideband 22 is fixedly connected on
Do the other side of the monomeric unit 3；
Several monomeric units 3 include several monomers 31 for prolonging horizontal direction and uniformly arranging；It is close on the monomer 31
Top position is equipped with a pair of symmetrically arranged dowel 1；A pair is equipped with close to bottom position on the monomer 31 symmetrically to set
The dowel 2 312 set；Dowel 1 is set between the top and bottom of monomer 31；Dowel 2 312 is set to monomer 31
Between top and bottom；Connection type between monomer 31 is for example, several monomers 31 are monomer one, monomer two, monomer
Three ...;The dowel 1 of one end of monomer two is connected with the dowel 1 of adjacent monomer one；Monomer two it is another
The dowel 1 at end is connected with the dowel 1 of adjacent monomer three.The connection of dowel 2 312 and dowel 1
Mode is the same, and the dowel 2 312 of one end of monomer two is connected with the dowel 2 312 of adjacent monomer one；Monomer two it is another
The dowel 2 312 of one end is connected with the dowel 2 312 of adjacent monomer three.
It is connected between several vertically arranged monomeric units 3 by several longitudinally connected muscle 4 uniformly arranged.
Four monomers are one group；The longitudinally connected muscle 4 is between group and group.
Two monomers are one group；The longitudinally connected muscle 4 is between group and group.
The thickness of the dowel 1 is successively passed by the laterally outside (side far from monomer) close to the monomer
Increase.
The thickness of the dowel 2 312 is successively passed by the laterally outside (side far from monomer) close to the monomer
Increase.
Connected between monomer one and monomer two, dowel 1 between the two, which merges, forms an entirety, from centre to
Successively decrease two sides；In blanking process, since intermediate weight is greater than the gravity of both side ends, waste material adhesion mold notch is reduced
Probability.
As shown in figure 4, monomer is divided into the upper half and lower half in figure；In process of production, trimming is carried out to rectangular frame
Before punching, the upper half of monomer and lower half are welded by wire jumper and chip；The upper half of monomer after being punched
It is to connect into an entirety between lower half.
