Problems solved by technology

Although the FPC board can be flexed and folded freely, it does not have stretchability. If the FPC board is stretched repeatedly, it will cause an open circuit on the FPC board and be scrapped. Therefore, the FPC board cannot be used in stretchable products.

Abstract

The invention relates to a stretchable FPC board and a manufacturing method thereof. The stretchable FPC board comprises an elastic substrate, a first rolled copper foil and a second rolled copper foil; and the first rolled copper foil is laminated on one side surface of the elastic substrate while the second rolled copper foil is laminated on the other side surface of the elastic substrate. According to the stretchable FPC board, the elastic substrate, the first rolled copper foil and the second rolled copper foil not only can be freely bent and folded, but also can be stretched to a certaindegree and can be recovered to the original shape after being stretched, so that product scraping is not caused after the stretchable FPC board is stretched.

Description

technical field [0001] The invention relates to an FPC board, in particular to a stretchable FPC board and a manufacturing method thereof. Background technique [0002] The traditional FPC (Flexible Printed Circuit, flexible circuit board) board is generally composed of copper foil + glue + substrate board or copper foil + substrate board, wherein the substrate board is a polyimide board, and the polyimide board has Excellent flexural properties, so that the FPC board has excellent flexural properties. Although the FPC board can be flexed and folded freely, it does not have stretchability. If the FPC board is repeatedly stretched, the circuit on the FPC board will be open and scrapped. Therefore, the FPC board cannot be used in stretchable products. Contents of the invention [0003] Based on this, it is necessary to overcome the defects of the prior art and provide a stretchable FPC board and a manufacturing method thereof, which can be stretched and will not lead to pro...
