Abstract
The invention relates to a soft and hard combined board for preventing a soft board from being bent or broken. The soft and hard combined board is characterized by comprising a soft board layer, wherein the surface of the circuit of the soft board layer is covered with an upper cover film and a lower cover film, and the size of the upper cover film and the size of the lower cover film are at least0.5 mm larger than that of a soft board bending area; a first upper prepreg and a first lower prepreg are arranged on the upper and lower surfaces of the substrate of the soft board layer, and firstwindows are formed in the first upper prepreg and the first lower prepreg corresponding to the soft board bending area; an upper hard board layer and a lower hard board layer are arranged on the surface of the first upper prepreg and the surface of the first lower prepreg, and second windows are formed in the upper hard board layer and the lower hard board layer corresponding to the soft board bending area; a second upper prepreg and a second lower prepreg are arranged on the surface of the upper hard board layer and the surface of the lower hard board layer, and third windows are formed in the second upper prepreg and the second lower prepreg corresponding to the soft board bending area. According to the soft and hard combined board, the soft and hard combined board can be prevented frombeing bent or broken, so that the quality and trustworthiness of the product are promoted.
Description
technical field [0001] The invention relates to a soft-rigid combination board for preventing flexible boards from being bent and broken, and belongs to the technical field of printed circuit boards. Background technique [0002] With the development trend of thinner, more integrated and multi-functional consumer electronic products, the requirements for the manufacturing process of printed circuit boards are getting higher and higher. Following this trend, rigid-flex printed circuit boards will gradually become an important part of printed circuit boards, and one type of rigid-flex printed circuit board with a cavity that can bury capacitance and resistance will also increase with market demand. Rigid-flex board, as the name implies, is one or more rigid printed circuit boards, including one or more flexible printed circuit boards that are indispensable to form a whole. Its function reduces the use of connectors when assembling electronic products, greatly increasing It ha...
