Abstract

The invention provides a flexibility and hardness combined circuit board. The flexibility and hardness combined circuit board comprises a flexible board and a hard board, wherein the flexible board which is made of pure copper comprises an upper surface and a lower surface, the upper surface of the flexible board is attached with an upper protective film, and the lower surface of the flexible board is attached with a lower protective film, and the flexible board and the hard board are bonded through hot-pressing glue. The invention further provides a method for manufacturing the flexibility and hardness combined circuit board. The pure copper of the flexible board is used for replacing a double-faced board, production procedure is reduced, device investment is saved, production cost is reduced, production efficiency and product yield are improved, the hard board is precut, and the purpose of conducting normal circuit manufacturing of the flexibility and hardness combining circuit board can be realized by the utilization of a common film drying machine.

Description

technical field [0001] The invention relates to a circuit board and a manufacturing method thereof, in particular to a soft-hard combination circuit board and a manufacturing method thereof. Background technique [0002] With the development and improvement of flexible printed circuit technology, the development and research of soft and hard combined circuit boards have been widely used. The durability and flexibility of soft and hard combined boards, and their strong resistance to harsh application environments make them replace rigid PCB is more suitable for medical and military applications. Rigid-flex circuit boards include soft boards and hard boards. The soft boards and hard boards are manufactured separately and then pressed into a single circuit board. Each rigid-flex circuit board has one or more rigid regions and flexible regions. Among them, the hard board has high flatness and mechanical strength, while the soft board has bendability and high degree of freedom. ...
