Cのパッケージの上面に接触し、ICを吸着する。The IC suction device 5 includes a hot chuck 5A,
The hot chuck 5A is composed of a suction pad unit 5C housed in a through hole 5B formed in the center and a rubber pad 5D attached to the tip of the suction pad unit 5C. The hot chuck 5A has a built-in heater therein, and is heated to a predetermined temperature when the temperature of the IC is tested, and the temperature is applied to the adsorbed IC so that the temperature of the IC does not decrease. The suction pad unit 5C is composed of a pipe having a threaded portion at the upper end, and the screwed portion is screwed into a screw hole formed in the mounting surface of the mount 4 to mount the suction pad unit 5C on the mount 4 and by this mounting, the suction pad unit 5C. The hollow hole of the unit 5C communicates with the pump connection hole 4B. The rubber pad 5D is attached to the lower end side of the suction pad unit 5C. The rubber pad 5D is formed in a suction cup shape, and its tip is slightly projected from the suction surface of the hot chuck 5A.
It contacts the upper surface of the C package and adsorbs the IC.

が起きる不都合がある。In order to bring the IC adsorbed on the rubber pad 5D into contact with the adsorbing surface 5E of the hot chuck 5A, the amount of protrusion of the rubber pad 5D should be small. However, if the amount of protrusion of the rubber pad 5D is set small, X-Y
Due to the parallelism error of the drive mechanism
There is an inconvenience of causing an accident that the IC is crushed by the IC suction device 5.

しまう事故が起きることになる。That is, the error between the IC stop position when the IC suction device 5 is lowered and the IC must be within the range of the protrusion amount of the rubber pad 5D. Therefore, if the amount of protrusion of the rubber pad 5D is made too small, the parallelism error of the XY drive mechanism cannot be absorbed by the amount of protrusion of the rubber pad 5D. That is, when the distance between the position of the horizontally moving rod 1 and the mounted IC is longer than the regulation, when the Z-axis driving means 3 lowers the IC suction device 5, the rubber pad 5D does not reach the IC. , Can not be adsorbed. Therefore, if the stop position of the IC suction device 5 is set low, the IC suction device 5 is lowered at a place where the distance between the position of the horizontal moving head 1 and the mounted IC is smaller than the regulation. In that case, an accident occurs in which the IC suction device 5 crushes the IC.

手間と時間が掛る不都合がある。In order to eliminate such an inconvenience, a large amount of protrusion of the rubber pad 5D may be adopted, and the stop position when the IC suction device is lowered may be set to a position apart from the IC mounting surface. However, when the amount of protrusion of the rubber pad 5D is large as described above, there is a disadvantage that the sucked IC cannot be brought into contact with the suction surface 5E of the hot chuck 5A. Therefore, in such a case, it is necessary to readjust the parallelism of the X-Y drive mechanism, which is inconvenient and time-consuming.

It is an object of the present invention to provide an IC suction device having a function of surely bringing the sucked IC into contact with the hot chuck.

The structure in that the IC suction device 5 is attached to the lower surface 4A of the above is the same as the conventional technique. The characteristic structure of the present invention is that the suction pad unit 5C housed in the through hole 5B formed in the hot chuck 5A is supported so as to be vertically movable. In the illustrated embodiment, the pipe-shaped suction pad unit 5C is housed in the through hole 5B formed in the hot chuck 5A so as to be vertically movable, and
A concave groove 5F is formed on the peripheral surface of the suction pad unit 5C in a direction parallel to the axis, and the hot chuck 5A is formed in the concave groove 5F.
An example in which the tip of a stopper 5G screwed in from the outer peripheral surface of the suction pad unit 5C is supported so that the suction pad unit 5C can be moved up and down within the range of the length of the groove 5F is shown.

る。When the suction pad unit 5C is located at the lowest position, the rubber pad 5D protrudes to the maximum from the IC suction surface 5E of the hot chuck 5A. Adsorption pad unit 5C
When is moved to the uppermost position, the lower end of the rubber pad 5D is pulled into a state substantially flush with the IC suction surface 5E of the hot chuck 5A. When the IC is not adsorbed on the rubber pad 5D, the adsorption pad unit 5C is located at the lowest position due to its own weight. Therefore, the rubber pad 5D is in the maximum projecting position when the IC suction device is lowered to suck the IC. The rubber pad 5D approaches the IC, and the opening / closing valve connected to the pump connection port 4B (not shown)
Open and start sucking air. When the rubber pad 5D approaches the IC package and the lower end of the rubber pad 5D comes into contact with the IC package when air suction is started,
The IC is attracted to the rubber pad 5D by the suction force of air. At this time, if the Z-axis drive means continues to descend, the rubber pad 5D is pushed toward the through hole 5B by a certain amount.

実に接触され、ICは加熱される。When the IC is adsorbed by the rubber pad 5D, the hollow hole of the adsorption pad unit 5C is closed by the IC package, so that the suction force of air is exerted on the adsorption pad unit 5C. As a result, the suction pad unit 5C moves upward by the suction force of the air, is sucked by the rubber pad 5D, the IC is surely brought into contact with the IC suction surface 5E of the hot chuck 5A, and the IC is heated.

内で可及的に離れた距離に設定することができる。As described above, according to the present invention, the rubber pad 5D approaches the IC in a state in which it is maximally projected from the suction surface 5E of the hot chuck 5A when the IC suction device 5 is trying to suck the IC. Therefore, the IC suction device 5 causes I caused by an error in horizontality of the XY drive mechanism.
Even if there is a height difference up to C, this height difference can be absorbed by the movement amount of the rubber pad 5D. In other words, when the hot chuck 5A is lowered and stopped, the distance between the IC suction surface 5E and the waiting IC does not have to be set to 0 as much as possible, and it is possible within the range of the movement amount of the rubber pad 5D. The distance can be set as far as possible.

装置を提供することができる。As a result, the height difference between the hot chuck 5A and the IC caused by the parallelism error of the XY drive mechanism causes the hot chuck 5A to crush the IC or the rubber pad 5D to be attracted without reaching the IC. There is no accident that cannot be done. Further, since it is not necessary to adjust the parallelism of the XY drive mechanism, it is possible to provide an IC suction device that is easy to manufacture.
