The present invention relates to a coverlay attaching system and a method thereof, and to a coverlay attaching system and a method for attaching a coverlay for protecting a pattern and the like of the substrate.

A conductive pattern constituting a circuit is printed on a substrate such as a printed circuit board and a flexible printed circuit board. A coverlay such as a polyimide film is pre-attached to the surface of the substrate in order to protect the pattern during the manufacturing process of the substrate, and the coverlay is not attached to the place where the electronic component should be mounted. It is not. An adhesive is applied to one surface of the coverlay, and the adhesive melts when heat is applied to the surface of the substrate. The adhesive of the coverlay is protected by a release paper, and a coverlay sheet composed of the coverlay, the adhesive and the release paper is wound and manufactured by a roll. In addition, the coverlay may be attached to protect the lead of the semiconductor in addition to the substrate.

Such attachment of the coverlay is almost always carried out by manual labor. The operator peels the release paper of the coverlay being pressed and aligns the surface of the substrate, and heats the coverlay by iron to attach the coverlay to the surface of the substrate. Attaching the coverlay to the surface of the substrate by the manual labor of the operator takes a lot of manpower and time, so the production cost is greatly increased, there is a problem that the productivity is lowered.

Korean Patent Publication Nos. 10-0543575 and 10-0575559 of the applicant disclose a coverlay attachment system for attaching a coverlay on a substrate.

Wind the coverlay sheet released from the cover race control. The press installed between the unwinder and the rewinder presses the coverlay sheet into a coverlay blank by the operation of the upper die and the lower die. The first blade of the upper die cuts together the coverlay of the coverlay sheet and the release paper, and the second blade cuts only the coverlay to produce a coverlay blank. A separating device provided downstream of the press peels the cover label from the release paper. The robot transfers and attaches the cover label from the peeling apparatus on the substrate which is vacuum-adsorbed to the vacuum table.

However, in the prior art coverlay attachment system disclosed in the above-mentioned documents, the coverlay sheet released from the cover race control is pressed into the cover label blank by the upper die and the lower die of the press, and then the cover label blank from the release paper. Since the film is peeled off, deformation due to shrinkage and expansion of the coverlay is greatly generated, which causes a problem of adhesion failure. In addition, when a cutting error occurs while the operation error of the press and the first blade and the second blade of the upper die are blunt, the contour of the cover label may not be cut accurately, resulting in a poor peeling of the cover label. In particular, when the coverlay is incompletely cut by the second blade, the coverlay blank cannot be peeled off. In addition, the cover label blank has a problem that the release paper is moved to one side of the coverlay so that one edge of the release paper is attached to the side of the coverlay or the adhesive, so that the release paper does not peel smoothly from the adhesive of the coverlay.
