[0001] The utility model relates to the technical field of pre-pressing equipment, in particular to a rolling pre-pressing device for FPC processing. Background Art

[0002] The flexible printed circuit board is a highly reliable and excellently flexible printed circuit board made of polyimide or polyester film as the substrate. It has the characteristics of high wiring density, light weight, thin thickness and good bending. It is mainly used in many products such as mobile phones, laptops, PDAs, digital cameras, LCMs, etc., which have achieved lightweight, miniaturization and thinness, so as to achieve the integration of component devices and wire connections. Epoxy flexible printed circuit boards have experienced more than 30 years of development since the realization of industrial production. Since the 1970s, it has entered the real industrialized mass production. Until the late 1980s, due to the advent and application of a new type of polyimide film material, flexible printed circuit boards have made FPCs without adhesives appear (generally referred to as "two-layer FPCs"). In the 1990s, the world developed a photosensitive cover film corresponding to high-density circuits, which made FPCs have a major change in design. Due to the opening up of new application fields, the concept of its product form has undergone a significant change, including expanding it to a wider range of substrates including TAB and COB. The high-density FPC that emerged in the second half of the 1990s began to enter large-scale industrial production. Its circuit patterns have rapidly developed towards a more subtle level, and the market demand for high-density FPC is also growing rapidly.
