Preferably, the shape in each hole adapts with the shape in described first group of its corresponding hole of Kong Zhongyu in described second group of hole.
Preferably, each hole also comprises the groove that is arranged at least one side of hole main body in described first group of hole.
Preferably, each in described second group of hole is enclosed its corresponding hole of described first group of Kong Zhongyu when described cover plate is fitted to described base plate and is put therein.
Preferably, be provided with respectively magnetic part at the frame of described base plate and the frame place of described cover plate, so that the closely adhesive when combining with described base plate of described cover plate.
The application of tool described in the utility model can effectively reduce the tool conversion times in printing and the reflux technique.
Description of drawings
Fig. 1 is the schematic diagram according to the tool of an embodiment of the present utility model.
Fig. 2 is according to the base plate 10 of described tool of the present utility model and schematic diagram after cover plate 20 combines.
Embodiment
Further set forth the utility model below with reference to accompanying drawing.Need to prove that accompanying drawing only is used for signal, do not limit the size, ratio of the parts of illustrating etc. at this point, and identical label represents same or analogous parts in the accompanying drawings.
Fig. 1 is the schematic diagram according to the tool of an embodiment of the present utility model.As shown in the figure, described tool comprises base plate 10 and the cover plate 20 that is complementary with base plate 10.Base plate 10 is used for carrying copper-clad base plate, for example ceramic copper-clad base plate (DBC).Carry out paster and typography at the copper-clad base plate that carries, on the base plate 10 that subsequently cover plate 20 is added to.According to the utility model, the frame of base plate 10 and cover plate 20 is respectively and adds magnetic design, this so that cover plate 20 can closely combine with base plate 10.Alternatively, can pilot pin be set in the frame portion of base plate 10, and at the frame portion setting of cover plate 20 lock screw corresponding with described pilot pin, so that when described cover plate 20 covers described base plate 10, described pilot pin can combine with described lock screw, thereby guarantees that cover plate and base plate do not misplace.
The shape of base plate 10 and cover plate 20 is complementary.Generally speaking, base plate 10 and cover plate 20 are square, but also do not get rid of circular grade for other shape.Be provided with first group of hole 100 on the base plate 10, correspondingly, cover plate 20 is provided with the second group hole 200 corresponding with first group of hole 100.The quantity in second group of hole 200 is identical with the quantity in first group of hole 100, further, the quantity in two groups of holes can with to be placed on base plate 10 on the quantity of copper-clad base plate identical, and the shape of each adapts with the copper-clad base plate shape that will place in first group of hole 100, just any one hole in first group of hole 100 also comprises the groove that is arranged at least one side of hole main body, in order to increase the heat conduction when making tool described in the utility model pass through reflow ovens after carrying copper-clad base plate, for example two opposite sides in the hole arrange respectively the first groove 101 and the second groove 103.
As mentioned above, the shape of each corresponding aperture in the shape of each in second group of hole 200 and the first group of hole 100 adapts to.The shape in first group of hole 200 is described below in conjunction with any one hole 202 in second group of hole 200 of figure and the hole 102 in first group of hole 100 corresponding with it.Such as has already been described, the shape in the hole 102 in first group of hole 100 and thereon device (such as, copper-clad base plate) shape to be placed adapt, and in this example, it is polygon, and the limit on its first direction 301 and second direction 302 is for the longest.The both sides that simultaneously 102 hole main body 1020 is positioned at first direction 301 and second direction 302 in the hole arrange respectively the first groove 101 and the second groove 103.Second group of hole 200 mesopore 202 be shaped as quadrangle, and when hole 202 fits to base plate 10 at cover plate 20, four limits in hole 202 are just enclosed and are put 102 in first group of hole 100, that is to say, hole 202 be positioned on first direction 301 and the second direction 302 the limit with the corresponding edge of the hole main body in hole 102, and the first groove 101 and the second groove 103 enclose and put therein; And hole 202 be arranged in illustrate third direction 303 and four directions just to enclose the hole 102 of putting first group of hole 100 to two limits of 304 to be positioned at third direction 303 and four directions two corresponding sides to 304.Wherein, hole 102 be positioned at third direction 303 and four directions two limits to 304 be hole 102 in Y-direction at a distance of two limits farthest, and to be positioned at two limits of first direction 301 and second direction 302 are holes 102 in hole 102 at directions X at a distance of farthest two limits.
Fig. 2 is according to the base plate 10 of described tool of the present utility model and schematic diagram after cover plate 20 combines.Be noted that to form the process cardinal principle that base plate 10 shown in Figure 2 combines with cover plate 20 as follows: place copper-clad base plate in each in first group of hole 100 of base plate 10, print, paster technique, then cover plate 20 is attached on the base plate 10.As shown in the figure, each in second group of hole 200 is just enclosed each of putting in first group of hole 100.
In this example, first group of hole 100 and second group of hole 200 of tool are the structure that four lines three is listed as, and therefore, can place three lead frames along the direction of row on cover plate 20.
As described in the background technology part, in the prior art, after in copper-clad base plate being placed into relevant tool, having carried out paster and typography, copper-clad base plate need to be taken out manually being placed into again on the backflow tool in tool, lead frame be assembled up carried out again reflow soldering simultaneously.This with regard to so that in the technique kind of required tool more and need to carry out changing tool in the process in technique, so the higher and required manual operation of production cost is more, causes production efficiency low, there is quality hidden danger in simultaneously repeatedly manual operation.
According to tool described in the utility model, after on the base plate 10 that copper-clad base plate is being placed into tool as shown in Figure 1, carry out paster and typography, then need not mobile copper-clad base plate, but directly cover cover plate 20, simultaneously lead frame is placed on the cover plate 20, thereby carries out reflow soldering.So, reduced the tool conversion, correspondingly reduced the manual operation number of times, avoided the quality hidden danger that may cause.
Although with reference to above-mentioned embodiment the utility model has been carried out detailed elaboration; but those of ordinary skill in the art is to be understood that; can make amendment or the part technical characterictic is equal to replacement embodiment of the present utility model; and under the spirit that does not break away from the technical solution of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
