Description

Lamination device

This work is related to a lamination device, especially a device that can eliminate static electricity on the film to ensure the output quality of the lamination sheet.

In the manufacturing process of printed circuit boards, before the substrate is exposed, a photoresist layer and a film adhered to the surface of the photoresist layer are formed on the upper and lower surfaces of the substrate, and after exposure, the film is peeled off to make the photoresist Layers are exposed for subsequent development and etching procedures. Generally, the thickness of the substrate for lamination is about 20 μm-25 μm. During the lamination process, if the temperature of the substrate is too high or too low, it will affect the quality of the lamination. Therefore, the current working temperature of the lamination must be Maintain it at around 50°C to achieve the best lamination quality. However, since the preheating equipment of the traditional film laminating machine is mostly installed at the front end of the conveying equipment, and the preheating equipment is far away from the film lamination processing place, after the substrate passes through the preheating equipment, it is often caused by the rapid heat dissipation of the substrate on the way of transportation. When entering the hot press mechanism, the working temperature is too low, resulting in poor film quality. If the preheating temperature is increased, it is easy to cause wrinkling of the thin plate after film lamination.

In order to improve the above problems, as shown in the TW M252545 "laminating machine and its heating mechanism" patent case, a solution is provided.

With the structure of the above lamination machine, better lamination quality can indeed be achieved. However, the conventional lamination processing method mainly adheres the upper and lower films to the upper and lower surfaces of the substrate with at least one hot pressing wheel of the hot pressing wheel device. In the process of pulling the film to separate the film from the release film, the film is charged with static electricity due to the easy generation of charges. When the film is attached to the substrate, high temperatures may be generated at the charged single or multiple points, causing The film at this position deteriorates and hardens, forming micro-bubbles between the film and the substrate and becoming a defective product; or the film at this position bursts due to high temperature. During subsequent processing, the bursting position is likely to cause a short circuit and affect the product. of quality.
