Description
Technical field
The utility model relates to a kind of chip and divides to frock, and particularly a kind of chip divides to box.
Background technology
The fabrication processing of diode is as follows: silicon chip P tints in face → and scribing → lead-in wire filling → sieve cartridge chip → welding → pickling → sliver → gluing → adhesive curing → mold pressing → Post RDBMS → plating → test, lettering → packaging → shipment.
In above-mentioned diode manufacture craft, during sieve cartridge chip, first on stripping machine, blue membrane DNA chip is peeled off, then the some chips after stripping are placed on screen tray, in this process, owing to being directly placed on screen tray, the polarity of chip is easily reversed, when causing arrangements of chips, polarity is inconsistent, in this case, can be adjusted by the artificial chip anti-to polarity, the tweezers that adjustment process uses can cause damage to chip table part, and this point is the electrical Yield lmproved (the electrical yield 85% of current industry) of this product of restriction.
Utility model content
The technical problems to be solved in the utility model is to provide one does not need artificial adjustment, can divide to box by the consistent chip of chip polarity simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of chip divides to box, its innovative point is: the screen tray cover plate comprising screen tray and coordinate with screen tray upper surface, the middle part of described screen tray upper surface has a rectangle screening tank A, the two ends of upper surface have some location holes extended side by side and along screen tray short-axis direction; Described screening tank A there are some location notch groups in matrix distribution, each location notch group is made up of the location notch that two are disposed adjacent side by side, steam vent is provided with bottom described location notch, suction hole is had in screen tray side, this suction hole is communicated with steam vent, and be connected with vacuum pump, and then chip is adsorbed in location notch; Described screen tray cover plate is a rectangular panel body, and the butt plate that can with screen tray dock contour with screen tray is installed in the side of bottom, this butt plate is provided with the rectangle screening tank B consistent with screen tray upper surface screening tank A, this screening tank A can be mutually through after screen tray docks with butt plate with screening tank B.
Further, the upper surface of described screen tray cover plate is curved, and stretches out the upper end of screen tray.
The utility model has the advantage of: chip of the present utility model divides to box, original screen tray is equipped with a screen tray cover plate, when blue membrane DNA chip is peeled off on a film by stripping machine, then screen tray cover plate is covered on film, then overall inversion makes the chip on film drop on screen tray to cover, finally screen tray is inverted and is placed on inverted screen tray and cover and dock with screen tray lid, be inverted overall again after connecting, enter next step sieve dress work, this course of work is simple, and no longer need artificial adjustment, just can ensure that the polarity of chip is consistent, improve the production efficiency of product.
The upper surface of screen tray cover plate of the present utility model is curved, and stretches out the upper end of screen tray, is convenient to screen tray cover plate is separated with screen tray.
Accompanying drawing explanation
Fig. 1 is the vertical view that a kind of chip of the utility model divides to box.
Fig. 2 is the cutaway view of A-A line in Fig. 1.。
Fig. 3 is the vertical view that a kind of chip of the utility model divides screen tray in box.
Fig. 4 is the vertical view that a kind of chip of the utility model divides screen tray cover plate in box.
Embodiment
As Figure 1-Figure 4, the utility model discloses a kind of chip divides to box, the screen tray cover plate 2 comprising screen tray 1 and coordinate with screen tray 1 upper surface, the middle part of screen tray 1 upper surface has a rectangle screening tank A3, the two ends of upper surface have some location holes 4 extended side by side and along screen tray 1 short-axis direction; Screening tank A3 there are some location notch groups in matrix distribution, each location notch group is made up of the location notch that two are disposed adjacent side by side, steam vent 6 is provided with bottom location notch 5, suction hole 7 is had in screen tray 1 side, this suction hole 7 is communicated with steam vent 6, and suction hole 7 is equipped with vacuum noz(zle) 8 and is connected with vacuum pump, and then chip is adsorbed in location notch 5; Screen tray cover plate 2 is by rectangular panel body 11 and the butt plate 9 being arranged on the side bottom rectangular panel body, butt plate 9 is contour with screen tray 1 and can dock with screen tray 1, butt plate 9 is provided with the rectangle screening tank B10 consistent with screen tray 1 upper surface screening tank A3, this screening tank A3 can be mutually through after screen tray 1 docks with butt plate 9 with screening tank B10.
In the present embodiment, for the ease of making screen tray cover plate 2 be separated with screen tray 1, the upper surface of screen tray cover plate 2 is curved, and stretches out the upper end of screen tray 1.
Operation principle: first chips some on blue membrane DNA chip are peeled off on same film by stripping machine, screen tray cover plate is covered on film, screen tray cover plate and film integral being inverted makes the chip on film drop on screen tray cover plate again, then screen tray is inverted and is placed on inverted screen tray and cover and dock with screen tray cover plate, be inverted overall again after connecting, enter next step sieve dress work, during sieve dress, there is suction hole screen tray side, thus is adsorbed on by chip in corresponding location notch.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
