Description
Technical Field
[0001] The utility model relates to the technical field of flexible circuit boards, in particular to a curved knife cutting tool for flexible circuit boards. Background Art
[0002] Flexible printed circuit board (FPC) is the "charming queen" among circuit boards. Compared with traditional rigid printed circuit boards (PCB), FPC has high wiring density, light weight and thin thickness. It can be bent, wound and folded freely, arranged arbitrarily according to spatial layout requirements, and moved and stretched arbitrarily in three-dimensional space, thereby achieving the integration of component assembly and wire connection.
[0003] As the competition in the electronics market becomes increasingly fierce, the cost price of flexible circuit boards has become the only weight in the competition between competitors. Therefore, it is particularly important to reduce material costs and improve product layout rates. Due to process limitations, the conventional product layout design of flexible circuit boards can only be cut with a straight knife. This process is very wasteful in the layout design of irregular-shaped products, and it is difficult to improve the layout step rate, and the cost price of the product cannot be reduced at the source. In order to increase the layout space of such products and reduce the original price, the company decided to develop a flexible circuit board curved knife cutting tool, review how to improve the layout design and production process, and improve material utilization, so as to solve the above technical problems.
