Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention is a method for continuously forming a photosensitive resin laminated film (commonly known as a dry film) into a frame shape so as to have uniform adhesion to the substrate without entrapping air. Crimp.

This invention relates to an automatic laminator for laminating layers.

[Prior art]

In recent years, the printing density of printed wiring boards has been increasing year by year, and resist image forming technology that exhibits high resolution has become important. In addition to the characteristics of the dry film, the resist image forming technology that maintains a high level of reliability and high resolution has extremely important meaning during the printed wiring board manufacturing process, especially from the lamination to the development process. Various conditions and management are required at the contact point between the resist and the resist. That is, the conditions include substrate roughness, substrate temperature, lamination temperature, lamination pressure, and lamination speed.

On the other hand, as densification increases, garbage is removed during lamination in order to increase manufacturing reliability and yield.

How to prevent contamination of resist chips and cutting powder has become an important issue at the industrial production stage.

Various picture frame cutting type laminators have been proposed to solve the above problems. For example, U.S. Pat.
No. 6, JP-A-56-49592, JP-A-59-110
No. 188, etc., but the frame cutting method laminates the dry film to the substrate after cutting, so there are fewer resist chips, and it is possible to laminate only the required length to the substrate, so the dry film can be used effectively and is economical. This is a laminating method.

The method described in the above-mentioned U.S. Patent No. 3,658,629 is held in a vacuum pail, tacked, and then laminated. When doing so, air entrapment and peeling from the tacking part may occur.The conditions are set in an extremely narrow range, and the dry film is not restrained and sways after being tacky to the board. However, the carrier film is thin and is difficult to use for dry films with no stiffness. It is possible to laminate the film by sliding it on the top while determining the lengthwise position, but it seems difficult to apply a dry film where the carrier film is thin and soft and has no stiffness.
In addition, the friction coefficient on the slide is affected by temperature and humidity, so moisture management of the dry film carrier film is important.

It is necessary to strictly control the temperature and humidity of the laminate atmosphere. The method disclosed in JP-A-59-110188 laminates both sides with a single sheet of dry film, and compared to the method of laminating in the shape of a picture frame, the loss of dry film is large and the time required to pull out the dry film is long. Therefore, the lamination cycle time needs to be longer than that for double-sided lamination, which poses a problem in productivity.

[Problem that the invention seeks to solve]

The present invention aims to solve the problems and difficulties of the prior art described above, and to provide a laminator that press-bonds a dry film in the shape of a picture frame, which can also be applied to a dry film using a thin and stiff carrier film. It is something to do.

[Failure to solve the problem]

The present invention provides a laminating device that pressure-bonds a continuously wound photosensitive resin layer film to a substrate, in which a large number of small holes are bored on an arcuate outer periphery, and cutting grooves are formed in the width direction of the arcuate surface. Then, a shoe provided with a heating section adjacent to the cutting groove for pre-pressing the edge of the photosensitive resin laminated film near the tip of the substrate is rotated in the direction toward or away from the substrate being conveyed. A main pressure roller is mounted so as to be freely reciprocated in a direction perpendicular to the substrate, and a main pressure roller is provided close to the substrate conveying direction side of the shoe, and a main pressure roller is provided in the conveyance path of the substrate. A detection device that detects the rear end of the substrate is provided, and the shoe is rotated to operate a cutting device that cuts the photosensitive resin laminated film to a predetermined length according to the length of the substrate by detecting the rear end of the substrate. This is a cutting and laminating device that uses a rotating shoe that operates while moving the machine.

[Effect]

If there is a cover film, remove it and hold and restrain the photosensitive resin laminated film (hereinafter referred to as dry film) consisting of two layers of carrier film and photosensitive layer on the outer periphery of the shoe without wrinkles until it reaches the pre-pressing position. rotating the shoe to pre-press the dry film held and moved by the shoe to the tip of the substrate being conveyed;
After the preliminary crimping, the tip of the transferred substrate is caught by a pair of main crimping hot rolls, and when the main crimping starts, the shoe is reversed and returned to the dry film cutting position, and as the substrate is transferred, the shoe is moved back to the dry film cutting position. The edge is detected by a detection sensor, the dry film is cut to a predetermined length while rotating the shoe at the same speed as the substrate transfer speed, and the cut end is held by the shoe as the dry film is cut. While holding the next dry film on the outer surface of the shoe, the shoe is rotated at the same speed as the substrate transfer speed to the preliminary crimping position, and stopped at the preliminary crimping position, and the cut dry film is As the board is transferred, it is moved away from the shoe and crimped onto the board, the shoe waits until the next board is transported, the board is transported and stopped at a predetermined position, and is pre-pressed, and the above operation is repeated to remove dust. This enables simple and stable lamination.

Next, the operation of the laminator of the present invention will be explained.
FIG. 3, which shows the order of operation, shows a pair of shoes A arranged above and below, and a schematic diagram for explaining the shoe A arranged above A.
The lower shoe etc. provided symmetrically with the other parts are omitted. Since the operation is the same for both the upper and lower parts, only the upper part will be explained.

If there is a resin laminated film with a cover film, the cover film is peeled off by the cover film peeling roller 20, the peeled cover film is taken up by the cover film winding roller 19, and the carrier film from which the cover film has been removed is taken up. The dry film X, which consists of two photosensitive layers, has a large number of small vacuum holes 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 6, 10, 10, 10, 3, 3, 3, , , , , , , , , , , , , , , , , a , a dry .・
... is adsorbed to the outer circumferential surface of the shoe A (see the opening in Figure 3). When the substrate 17 is carried in, the detection device 16 detects the tip 17a of the υ substrate 17, and this detection activates a timer to stop the substrate 17 at a pre-pressing position, which will be described later. While X is attracted to the outer peripheral surface, the shoe A is quickly rotated around the support shaft 1, and the heating section 5 provided on the shoe A is rotated to a predetermined position facing the conveyance path of the substrate 1γ and then stopped. , waits until the substrate 17 is transported. When the tip 17a of the substrate 17 reaches a position facing the heating section 5 of the shoe A, the movement of the substrate 17 is stopped,
The shoe A is moved to the board 17 by operating a mechanism such as an air cylinder.
The dry film X is preliminarily pressed to a predetermined position on the substrate 17 by the heating unit 5 (see the opening in FIG. 3). When the preliminary pressure bonding is completed, the suction of the shoe A is stopped, and the shoe A is moved vertically in the opposite direction to that described above, that is, in the direction away from the substrate 17, by the air cylinder mechanism as described above (see FIG. 3). On the other hand, after the preliminary pressure bonding is completed, the substrate 17 starts to move in the direction of the main pressure bonding roll 7.7 with the dry film preliminarily bonded to a predetermined position at the leading end.

Since the main crimping hot roll 7.7 is provided close to the position where the shoe A is in the preliminary crimping position, the transfer of the substrate 17 to the main crimping hot roll 7.7 is extremely smooth. Then, the substrate 17 is transferred to the main pressure bonding roll 7.7, and the main pressure bonding of the dry film X is started (see FIG. 3). When this main crimping is started, the shoe A moves the dry film X around the spindle 1.
The cutting device 8 is quickly reversed so that the cutting groove 4 of the shoe A coincides with the first predetermined position (see FIG. 3). The substrate 17 moves further and the main crimping progresses, and the rear end 1 of the substrate 17
7b is detected by the detection device 16, suction to the shoe A is started, the shoe A is rotated at the same speed as the conveyance speed of the substrate 1γ, and at the same time, the cutter guide holder 9 of the cutting device 8 is rotated. The shoe A is also rotated at the same speed as the shoe A.

Further, the cutter drive motor 82 is also driven by the detection signal, rotates the cutter 81, and the cutter 81 connects the outer surface of the shoe A with the main body of the cutter guide holder 90 through the slit 12 of the cutter guide holder 9. The dry film The dry film X is rotated from one side of the guide holder 9 to the other and cut into a predetermined length corresponding to the length of the substrate 17 (see FIG. 3). When cutting is completed, cutter 8
1 moves the cutter 81 in the direction away from the plane of the cutter guide holder 9, or moves the cutter 81 away from the cutter guide holder 9.
By positioning it so as to be spaced apart from the axial end of the shoe A, the shoe A is disengaged from the cutting groove 4 of the shoe A and the slit 12 of the cutter guide holder 9, and the rotation of the cutter guide holder 9 is stopped. , immediately invert and prepare for the next cut.

On the other hand, as described above, the shoe A is rotated during and after cutting the dry film X, and the end of the cut dry film There is no danger of it hanging down, and the substrate 17 continues to move even when the dry film X is cut, and the shoe A attracts the end of the cut dry film , and the next dry film X is rotated at the same speed as the movement of the substrate 17 while adsorbing the next dry film X to the arcuate outer circumferential surface of the shoe A. The end portion of the cut dry film adsorbed by the outer peripheral layer extension adsorption portion 3 of the shoe A described above leaves the shoe A and is transferred to the main pressure bonding hot roll 7.
7 together with the substrate 17, the main crimping hot roll 7.7 has the shoe A in a predetermined position for preliminary crimping.
position, that is, the position where the rotation of the shoe is stopped, so that the end of the dry film .7, the dry film X and the substrate 17 can be pressed together very well without any air being trapped between them.

When the substrate 17 is conveyed and moved while the end of the dry film X is separated from the shoe A and is crimped onto the blank board 17 by the main crimping roll 7.7, the shoe A is stopped at the preliminary crimping position. 5. Wait until the next substrate 1T is conveyed, then the next substrate 17 is conveyed, and when its tip reaches the preliminary crimping position, the substrate is stopped (see Fig. 1).
Preliminary crimping is performed by the vertical movement of the press, and the above-described operations are repeated. By laminating the dry film inside the substrate in this way, it is possible to laminate it into a picture frame shape as shown in FIG.

As the embodiment of the present invention is as described above, the dry film Therefore, it is possible to eliminate the trapping of air etc. when laminating the dry film on the substrate.
When cutting to a predetermined length corresponding to the length of 7, a large number of small holes 6, 6 for vacuuming are also formed at the bottom of the cutting groove 4.
・Since it is open, chips can be sucked υ. When the dry film is cut while rotating the shoe A, the cut end is removed by the outer peripheral layer extension suction part 3 of the shoe A. Since it is adsorbed, there is no risk of it hanging down, and the main pressure hot roller 7.
The transfer to the shoe A iC can be carried out extremely smoothly since the above-mentioned outer peripheral layer extension suction part 3 is formed and the cut end can be held until the end.
Furthermore, since the cutting device is operated while the shoe A is rotating, there is no need to stop the board while laminating dry film on the board. Good lamination properties can be obtained without any change in thickness.

Furthermore, in order to pre-press the dry film onto the substrate, in the above-mentioned embodiment, the unit A is moved in the vertical direction by an air cylinder mechanism, but in the embodiment shown in FIG. Preliminary pressure bonding can be performed by moving only the slidable heating parts s', s' in the vertical direction by an air cylinder mechanism.

The dry film is sucked and held, and since the shoe is rotated and the cutting device is operated when cutting the dry film, the dry film can be removed without stopping the board while laminating the dry film on the board. Since the film is cut to length, there are no streaks or the like that occur when cutting the dry film by temporarily stopping the board and 7U as in the past, and there is no change in thickness.
In addition, a good lamination with no air entrapment can be obtained, and the leading and trailing edges of the board can be detected when stopping the board during preliminary crimping, rotating and reversing the shoe, and cutting the dry film. This process is carried out automatically, and it is possible to laminate with an extremely simple operation.
