Abstract

A rigid-flex circuit substrate, comprising: a flexible circuit board, a core substrate, a first lamination film, a second lamination film, a third conductive circuit layer and a fourth conductive circuit layer, the flexible circuit board It includes an exposed area and a pressing area connected to the exposed area. The core substrate is connected to the pressing area. The first lamination film and the second lamination film are formed on both sides of the lamination area of ​​the core substrate and the flexible circuit board. An electrical connector is formed in the core substrate, the first and the second laminated film, and the conductive circuit layer of the flexible circuit board is electrically connected with the third conductive circuit layer and the fourth conductive circuit layer through the electrical connector. The present invention also provides a manufacturing method of the rigid-flex circuit board, a rigid-flex circuit board and a manufacturing method thereof.

Description

technical field [0001] The invention relates to the field of circuit board production, in particular to a rigid-flex circuit substrate and a manufacturing method thereof, a rigid-flex circuit board and a manufacturing method thereof. Background technique [0002] Printed circuit boards have been widely used due to their advantages such as high assembly density. For the application of the circuit board, please refer to the literature Takahashi, A. Ooki, N. Nagai, A. Akahoshi, H. Mukoh, A. Wajima, M. Res. Lab, High density multilayer printed circuit board for HITAC M-880, IEEE Trans . on Components, Packaging, and Manufacturing Technology, 1992, 15(4): 1418-1425. [0003] Rigid-flex circuit board is a circuit board structure including interconnected flexible boards and rigid boards, which can not only have the flexibility of flexible circuit boards, but also include the hardness of rigid circuit boards. In the production process of the flexible and rigid circuit board, it is...
