Abstract

The invention discloses a preparation method of an ultra-long flexible circuit board. The ultra-long flexible circuit board is exposed in a segmented manner, and cannot be limited by the structure of an exposure machine, so that preparation of the ultra-long flexible circuit board is realized; meanwhile, an exposure locating point is arranged on each segment of circuit diagram for alignment of the next segment of circuit diagram; only an initial locating hole needs to be drilled or punched for accurately locating together with a conducting hole in the plate; the locating point which is exposed previously is adopted for accurately locating in subsequent exposure; and the subsequent exposure is not affected by product expanding and shrinking and accumulative deviation in the processing process. Therefore, the preparation method is simple in process, high in accuracy, low in cost and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a method for preparing an ultra-long flexible circuit board. Background technique [0002] Flexible circuit board (FPC), also known as flexible circuit board or flexible circuit board, is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the base material. Due to the particularity of its base material, special-shaped boards or super-long boards with unlimited shapes and sizes can be prepared. Among them, super-long flexible circuit boards usually refer to circuit boards with an uninterrupted circuit length of more than 1 meter, which are often used to make large-scale flexible circuit boards. Equipment signal transmission lines, LED light strips, large printed antennas, etc. [0003] In the field of printed circuit boards, circuits are made on copper clad laminates. The pattern of the entire circuit is transferred to the mask by ...
