- the adhesive tape to which the release tape is attached is cut. Thereby, an individual piece with a release tape is prepared. This individual piece moves while being held by the holding mechanism. Thereafter, the individual pieces are placed at predetermined positions on the substrate by the holding mechanism. This step is called a temporary crimping step.
- the individual pieces placed on the substrate are pressed against the substrate by a pressing mechanism. Thereby, an individual piece is stuck to a predetermined position on the substrate. That is, one main surface of the adhesive film is attached to the substrate.
- This step is called a final crimping step. After the completion of this step, the release film still remains on the main surface of the individual piece on the side opposite to the surface where the individual piece contacts the substrate.
- the adhesive tape is pressed against the individual release film on the substrate. As a result, the release film adheres to the adhesive tape. Thereafter, when the adhesive tape is transported, the release film is removed from the substrate. Therefore, only the adhesive film remains on the substrate. This step is called a peel-off step. After the peel-off step, the other major surface of the adhesive film is exposed.
- the adhesive tape 104 is cut to a required size at a position 105.

Therefore, no matter how quickly each of Step S and Step W is performed, it is difficult to significantly reduce the time of the entire temporary crimping step.

- the temporary crimping step cannot be performed with high accuracy. That is, it is not possible to perform the temporary pressure bonding step quickly and with high accuracy.
- the adhesive tape and the release film used in the peel-off step are transparent. Therefore, when an infrared sensor is used, it cannot be detected that the release film has been removed from the adhesive tape. Even if the material of the release film is opaque, it is difficult to quickly detect that the release film has been removed by the infrared sensor. Therefore, after the adhesive tape is attached to the substrate, the electronic component cannot be quickly attached to the adhesive tape.

- Each of the mounting table 26 and the crimping table is provided with a heating mechanism (not shown).
- the individual pieces 12 are attached to the substrate 1 by the action of the heating mechanism. Therefore, the adhesive film 10 is more likely to adhere to the substrate 1.
- the heating mechanism may be provided in the holding mechanism 13 or the pressure bonding mechanism 15 which is not provided in the mounting table 26 and the pressing table.
- the peel-off unit 9 is provided with a release film removing mechanism 16 shown in FIG.
- the release film removing mechanism 16 includes an adhesive tape 17 for removing the release film and a pressing mechanism 18.
- the release film removing mechanism 16 includes a peel-off table 33, a take-up roller 34, a color sensor 35, and a detection board 36.
- the peel-off table 33 is provided so as to face the pressing mechanism 18 via the substrate 1.
- the take-up roller 34 is used to take up the adhesive tape.

- the peel-off table 33 is provided with a cooling mechanism (not shown) so that only the release film 11 is easily removed from the individual pieces 12 having the two-layer structure.
- This cooling mechanism cools the heat-generating portion (12 pieces on the substrate 1) in the peel-off step.
- the material of the distal end portion of the pressing mechanism 18 is a material having elasticity, such as a fluororesin. With such a configuration, the adhesive film 10 is prevented from being damaged by excessive pressing force. Also, it is possible to apply a substantially uniform pressure to the adhesive tape 17.
- the release film removing mechanism 16 shown in FIG. 8 is provided with an adhesive tape supply mechanism (not shown) for applying a pulling force to the adhesive tape 17 or for reducing the pulling force.
- This tape supply mechanism has a pair of reels. The pair of reels are wound around a sending reel for sending out the adhesive tape 17 toward the piece 12 occupied by the shell 1 on the substrate 1 and an adhesive tape 17 to which the release film 11 removed from the piece 12 is adhered. And take-up reel.
- a color sensor 35 is provided between the peel-off table 33 and the take-up reel.
- the color sensor 35 is a sensor that can detect a color. Therefore, the peeling If one color is applied to the lum 11 in advance and another color different from the one color is applied to the adhesive tape 17, the release film 11 can be easily detected. As a result, whether or not the release film 11 has been removed from the adhesive tape 3 can be quickly grasped.
- the color sensor 35 detects the release film 11, for example, even if a step of attaching the chip 40 to the adhesive tape 10 on the substrate 1 from which the detected release film 11 has been removed is performed.
- the color sensor 35 does not detect the release film 11, a step of attaching the chip 40 to the adhesive tape 10 on the substrate 1 where the undetected release film 11 remains without being released. This work may be stopped without performing the. Further, when the color sensor 35 does not detect the release film 11, it is considered that an abnormal operation has occurred in which the adhesive tape 10 is not properly affixed to the substrate 1, and a warning such as a buzzer is issued. By means, the occurrence of this abnormality may be notified to the operator.
- the detection board 36 shown in FIG. 8 is for detecting one color applied to the release film 11 with the color sensor 35 more accurately. Therefore, the surface on the side of the adhesive tape 17 of the detection board 36 is given another color different from the one color given to the release film 11.
- the detection board 36 is not an essential component of the present invention.
- each of the release film 11 and the adhesive tape 17 can be used. Since different colors are attached to the adhesive film 10, it is possible to accurately and quickly detect whether or not the release film 11 has been removed from the adhesive film 10 by the color sensor 35.
- the above-described peel-off step is not performed, and only the temporary pressure-bonding step and the main pressure-bonding step are performed. May be done.
