Description

Detailed Description of the Invention (1) Purpose of the Invention [Field of Industrial Application] The present invention relates to a thin film sticking device, and is particularly applicable to a thin film sticking device that sticks a thin film on the surface of a substrate. It is related to effective technology.

[Prior Art] Printed wiring boards used in electronic devices such as computers have a predetermined pattern of wiring made of copper or the like formed on one or both sides of an insulating substrate.

This type of printed wiring board can be manufactured by the following manufacturing process.

First, a laminate consisting of a photosensitive resin (photoresist) layer and a transparent resin film (protective film) for protecting it is laminated by thermocompression on a conductive layer provided on an insulating substrate. This thermocompression laminate.

Mass production is carried out using a thin film pasting device called a laminator.

Thereafter, a wiring pattern film is placed on the laminate, and the photosensitive resin layer is exposed to light for a predetermined period of time through the wiring pattern film and the transparent resin film. After the transparent resin film is peeled off using a peeling device, the exposed photosensitive resin layer is developed to form an etching mask pattern. Thereafter, unnecessary portions of the conductive layer are removed by etching, and the remaining photosensitive resin layer is further removed to form a printed wiring board having a predetermined wiring pattern.

[Problems to be Solved by the Invention] In the manufacturing process of the printed wiring board described above, a laminate consisting of a photosensitive resin layer and a translucent resin film is laminated by thermocompression on the conductive layer 711 of the insulating substrate. process is required.

The laminate to be applied to the insulating substrate is obtained by cutting the laminate continuously wound around the supply roller of the thin film adhering device into a size corresponding to the size of the insulating substrate.

The laminate wound around the supply roller has a three-layer structure including a translucent resin film, a photosensitive resin layer, and a translucent resin film. This feed roller stack is applied before being pasted onto an insulating substrate.

The light-transmitting resin film on the adhesive side of the photosensitive resin layer is peeled off. This peeled translucent resin film is wound up with a winding roller.

This type of thin film pasting device has one
g (The feed roller is removably attached to the back of the device body, and the take-up roller is detachably attached to the front side of the device body.The supply roller is quite heavy, and one operator cannot move it around the device body.) Attachment, replacement, etc. of the supply roller were carried out while supporting the supply roller on the back side.Therefore, there was a problem in that the efficiency of the supply roller attachment work was extremely poor.

Furthermore, there is a problem in that the work of attaching the supply roller is dangerous, as the supply roller may fall when the supply roller is attached or replaced.

The above-mentioned and other problems and novel features to be solved by the present invention will become clear from the description of this specification and the accompanying drawings.
