Abstract
The utility model discloses a ceramic suction head, which comprises a ceramic suction head front end (1) and a ceramic suction head rear end (2), wherein a hollow cavity (3) is arranged between the ceramic suction head front end (1) and the ceramic suction head rear end (2). Compared with silicon and aluminum used for making diodes and triodes, the material of the ceramic suction head provided by the utility model is harder, and not easy to wear, thereby greatly improving the production relative stability and the chip loading rate from less than 90% of the traditional plastic suction head to more than 99%; and a great amount of cost for materials and manpower resources is saved.
Description
Technical field
The utility model relates to the suction nozzle that a kind of bonding die operation is used.
Background technology
The employed material of the production of bonding die operation comprises suction nozzle, chip, framework etc., and what chip and framework carried out bonding use is the plastic cement suction nozzle.But use the plastic cement suction nozzle pick up the small size chip carry out when bonding because of plastic cement suction nozzle material hardness ratio two, the silicon of triode, aluminium material soft, suction nozzle is when pick-up chip, die area is more little, contact-making surface is also just more little, and because of product technology difficulty in bonding process bigger, so very easily cause the wearing and tearing of suction nozzle, lose very big.The loss of suction nozzle: suction nozzle can reach 300,000 output substantially producing large size chip, and that the small size chip has only is trivial less than 50,000, and so googol amount gap causes a large amount of loss of suction nozzle.The loss of chip: after the suction nozzle wearing and tearing, when picking up tube core, can cause tube core to pick up, too small because of die area, cannot pick up by secondary, the last core rate of chip is descended, and cause the loss of tube core cost.The loss of material: tube core can't pick up and just can't be bonded on the framework, and that does not have in the pipe operation afterwards of tube core (plastic packaging, electroplate, cut muscle, test) all to cause the wide variety of materials loss.Especially be embodied on the yield rate, producing the large size chip yield rate can reach more than 97%, and the small size chip will reach 90% all very difficult.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of not easy to wear, ceramic suction nozzle that yield rate is high, thereby overcomes the deficiencies in the prior art.
For solving the problems of the technologies described above the technical solution of the utility model: a kind of ceramic suction nozzle, constitute by the suction nozzle rear end of the suction nozzle front end of pottery and pottery, in the suction nozzle rear end of the suction nozzle front end of pottery and pottery, be provided with cavity.
In the above-mentioned ceramic suction nozzle, the inclination angle δ of described suction nozzle front end is 30 degree.
The beneficial effects of the utility model: compared with prior art, the utlity model has the advantage that traditional plastic cement suction nozzle can't replace: 1, on the ceramic suction nozzle material of the present utility model than two, the silicon of triode, aluminium is hard, not easy to wear when pick-up chip like this.As long as operating personnel's adjustment equipment puts in place, make the equipment operation normal, ceramic suction nozzle can not damage.According to producing 100,000,000 small size chips year, can consume 2000 suction nozzles less.2, suction nozzle not easy to wear makes and produces that the core rate is greatly improved on relative stability, the chip, and yield rate is brought up to more than 99% less than 90% from the plastic cement suction nozzle, can save 10,000,000 chips in 1 year.3, the raising of yield rate makes each operation no longer cause waste on raw material such as framework, plastic packaging material, electroplate liquid, and operating personnel are no longer flogged a dead horse, and has saved a large amount of costs on material and human resources.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment.As shown in Figure 1, ceramic suction nozzle of the present utility model is made of the suction nozzle rear end 2 of the suction nozzle front end 1 of pottery and pottery and connects as one, and is provided with cavity 3 in the suction nozzle rear end 2 of the suction nozzle front end 1 of pottery and pottery, and the inclination angle δ of suction nozzle front end 1 is 30 degree.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
Claims (2)
