Description

Indirect hot pressing film structure

This invention relates to an indirect hot pressing film structure, especially one that can simplify components and effectively increase the speed of lamination processing.

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. After exposure, the film is peeled off to remove the photoresist. The layer is exposed for subsequent development and etching processes. Generally, the thickness of the substrate used for lamination is about 20μm-25μm. 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 traditional laminating machines is mostly installed in front of the conveying equipment, and the preheating equipment is far away from the laminating processing place, after the substrate passes through the preheating equipment, the substrate often dissipates heat quickly during transportation, causing the substrate to dissipate rapidly. When entering the hot pressing mechanism, the working temperature is too low, resulting in poor lamination quality. If the preheating temperature is increased, it is easy to cause wrinkles on the sheet after lamination.

In order to improve the above problems, as shown in the patent case TW M252545 "Laminator and Heating Mechanism", a solution is provided. The laminator includes a hot pressing wheel device, a conveying mechanism and a thermal transfer mechanism.

It has a heating source and at least one set of first transfer rollers and second transfer rollers. The heating The source uses heat radiation to supply the heat source to the thin plate and the first and second transfer rollers, and uses the first and second transfer rollers to conduct the heat source to the processed thin plate in the form of rolling heat conduction. In this way, before the conveying mechanism enters the lamination process, the processed thin plate can use the heating program provided by the heat transfer mechanism to control the thin plate at an operating temperature of about 50°C, thereby providing the best lamination quality of the thin plate.

Through the structure of the laminating machine mentioned above, better laminating quality can indeed be achieved. However, the heating source of the conventional heat transfer mechanism uses thermal radiation to supply heat to the sheet and the first and second transfer rollers at the same time, and uses the first and second transfer rollers to conduct heat by rolling.
