Description

Technical Field

[0001] The utility model relates to the technical field of FPC production, in particular to a roll-to-roll full-laser dry-process FFC production device. Background Technique

[0002] In recent years, with the continuous increase in the market demand for consumer electronic products led by mobile electronic devices such as smart phones and tablet computers, it has greatly promoted the market development of FPC, which is an important connection accessory for them. At the same time, the rise of electric vehicles and the development of automotive intelligence have led to a relatively fast growth rate in the demand for in-vehicle FPC. In addition, the rapid development of emerging consumer electronic product markets such as wearable intelligent devices and drones has also brought broad growth space for FPC products.

[0003] With the gradual development of consumer electronic products towards miniaturization, portability and multi-functionality, the requirements for the refinement degree of FPC are also gradually increasing. At the same time, in order to improve the production efficiency and yield rate of FPC, reduce production costs and meet the trend of product refinement development, enterprises have gradually adjusted and improved the production process, and the roll-to-roll FPC production process and the full-dry-process FPC manufacturing process have been gradually promoted and applied.

[0004] The process of traditional FPC manufacturing is as follows:

[0004]

[0005] Cutting (cutting the roll material into the required size) → Baking (drying the moisture of the base material to avoid swelling, shrinking and delamination) → Laminating dry film (applying a layer of photosensitive dry film on the copper foil surface) → Exposure (exposing according to the film corresponding to the work order to transfer the image of the circuit pattern negative to the dry film) → Development (dissolving the unexposed dry film with sodium carbonate solution to form a dry film pattern) → Etching (etching the copper foil not protected by the dry film to form a circuit) → Stripping (removing the exposed dry film on the protected circuit) → Pretreatment (cleaning the board surface by chemical cleaning or sandblasting to remove oxidation and surface roughening) → Laminating cover film (aligning the cover film with the marking line and sticking it on the board, and pre-fixing the cover film with high heat) → Pressing (pressing under high temperature and high pressure) → Curing (baking at high heat to cure the thermosetting adhesive between the cover film and the board) → Surface treatment (mainly performing immersion gold or gold plating on the FPC surface) → Electrical testing (checking whether there are open circuits, short circuits, four-line defects, etc. between different networks of the board through a test fixture or equipment) → Assembly (sticking the reinforcement or electromagnetic film to the product according to the alignment marking line or hole position by means of manual fixtures, equipment, etc.) → Pressing (pressing under high temperature and high pressure) → Curing (baking at high heat to cure the thermosetting adhesive between the cover film and the board) → Lettering (printing the lettering ink on the product through the principle of screen printing) → Shaping (forming the final product shape of the customer through punching die blanking or laser cutting) → Final inspection (fully inspecting the product appearance and surface condition through manual visual inspection, CCD, equipment, etc.) → Packaging (packaging and shipping according to the customer's requirements)

[0006] The process flow of the roll-to-roll dry FPC device is as follows:

[0007] Unwinding → Laser circuit manufacturing (the laser cuts the copper foil layer according to the contour of the imported circuit diagram. After processing, the waste material is separated from the coil by the waste separation roller, and the waste material is sent to the waste winding roller for waste winding) → AOI appearance inspection → Cover film pasting (perform the cover film pasting operation on the tested circuit board) → Laser windowing (perform windowing treatment on the circuit board after pasting the cover film through the laser)

[0008] It can be seen from the comparison that the process of the roll-to-roll dry FPC device (from unwinding to laser windowing) can replace some processes of the traditional wet method (from blanking to lamination and curing).
