Description

Technical Field

[0001] The present application relates to the technical field of FCCL board processing, and in particular to an automatic laminating and separating device for double-layer FCCL boards. Background Art

[0002] Flexible copper clad laminate (FCCL) is the processing substrate material of flexible printed circuit board (FPC). It is composed of flexible insulating base film and metal foil. FPC with FCCL as substrate material is widely used in electronic products such as mobile phones, digital cameras, digital video cameras, automotive satellite positioning devices, LCD TVs, and laptop computers.

[0003] The traditional process of making single-sided blind via boards in double-sided or multi-layer FPC boards first involves the production process of single-sided circuits. After this step is completed, subsequent processing stages such as lamination are entered. During this process, to ensure that the copper foil on the other side without circuit processing is not damaged or oxidized, it is protected by film covering. However, at this stage, the copper foil on this side does not participate in direct product output. Using film to protect the unprocessed copper foil will increase the cost of materials and processes, and the additional film covering and removal steps will increase production time, thereby reducing overall production efficiency.
