Problems solved by technology

Traditionally, rigid-flex circuit boards are usually laminated and then pressed out at one time, but for rigid-flex circuit boards with flying tail structures, if the traditional rigid-flex circuit board manufacturing method is used, the The solder resist layer on the second rigid area is easily crushed, resulting in unqualified circuit board quality

Embodiment Construction

[0038] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0039] Such as figure 1 As shown, a rigid-flex circuit board with a flying tail structure includes a first rigid region 100, at least two flexible regions 200, and a second rigid region 300 equal in number to the flexible regions 200. The first rigid region One end of 100 is respectively connected to one end of the flexible zone 200, and the other end of the flexible zone 200 is respectively connected to one of the second rigid zones 300, and each second rigid zone 300 is on the solder-proof zone on the adjacent end surface. A polyetherimide cover film 400 is attached.

[0040] The rigid-flexible circuit board with the flying tail structure described in this embodiment is a rigid-flexible circuit board with sixteen layers of circuits 800, which includes two second rigid regions 300 and two flexible regions 200. The polyetherimide cover film 400 is pasted on ...

Abstract

The invention discloses a method for manufacturing a rigid-flex circuit board with a flying tail structure. Core boards, at least one layer of rigid core boards, each core board is stacked and pressed together to produce a sub-board equal to the number of the second rigid area, and the sub-board includes a part of the first rigid area, a flexible area, a The second rigid area; step 2: stack the sub-boards obtained in step 1, and paste a polyetherimide cover film on the solder-proof area of ​​the adjacent end face of each second rigid area; step 3: in the adjacent flexible area PTFE gaskets are placed between the adjacent second rigid areas, and the sub-boards processed in step 2 are pressed together, and part of the first rigid areas of each sub-board are pressed together to form the first rigid area. The invention also discloses a rigid-flex combined circuit board with a flying tail structure. The manufacturing method of the rigid-flex circuit board with the flying tail structure can effectively prevent the solder resist layer from being damaged.

Description

technical field [0001] The invention relates to a printed circuit board manufacturing technology, in particular to a rigid-flex combined circuit board with a flying tail structure and a manufacturing method thereof. Background technique [0002] The rigid-flex circuit board is developed on the basis of rigid circuit boards and flexible circuit boards. It inherits the characteristics of rigid circuit boards and flexible circuit boards. It has small size, light weight, flexible structure, and three-dimensional Advantages such as assembly, more and more people's attention. Rigid-flex circuit boards are in line with the trend of miniaturization and portability of electronic products today, and the market demand for them is increasing day by day. [0003] The flexibility of the rigid-flex circuit board also determines the diversity of its structure. The diversity of its structure brings certain difficulties to production, especially the rigid-flex circuit board with a flying tai...
