Problems solved by technology

[0003] At present, some rigid-flex boards on the market are static flexures (that is, customers only have flexion requirements during installation), and the cost of using high-flexibility flexible board materials is relatively high, while ordinary FR4 materials cannot meet the flexure requirements.

Embodiment 1

[0025] The invention discloses a method for preparing a soft-rigid combination board. A new type of soft-hard combination board similar to a soft-hard combination board is prepared by optimizing the lamination structure, drilling dirt treatment, and strictly controlling the depth of the blind gong. Its preparation method specifically comprises the following steps:

[0026] (1) Cutting: Make circuit graphics on the surface of FR4 board and SB120 board, and then brown the cutting surface;

[0027] (2) Lamination: Pair the corresponding FR4 board with the SB120 board, laminate the boards and press them together; the stacking method is from bottom to top: steel plate-reverse copper foil-FR4 board-PP-SB120 board- Reverse copper foil-false plate-reverse copper foil-steel plate; gong edge after pressing;

[0028] (3) Drill through holes: drill through holes 0.71mm, SB120 board upwards, the minimum drill tip is 0.5mm; adopt the combination of plasma cleaning + PI adjustment liquid to...

Abstract

The invention relates to a preparation method for a soft-hard combination plate, and belongs to the technical field of plate material application development. Through carrying out the stitching and stacking optimization and drilling sewage treatment and strictly controlling a milling depth, the method achieves the preparation of a novel soft-hard combination plate which is similar to this type of soft-hard combination plates. On the basis of a semi-flexible material SB120, a plate material is stitched with an FR4 plate material, and the novel soft-hard combination plate which is similar to this type of soft-hard combination plates is developed. The novel soft-hard combination plate can meet the requirements of a customer who just needs the static flexibility characteristics, thereby greatly reducing the preparation cost, overcoming the technical difficulties of the soft-hard combination plate, and reducing the preparation cycle.

Description

technical field [0001] The invention relates to a method for preparing a rigid-flex board, and belongs to the technical field of board application and development. Background technique [0002] The birth and development of FPC and PCB gave birth to the new product of soft and hard board. Therefore, the soft and hard combination board is the flexible circuit board and the rigid circuit board, which are combined according to the relevant process requirements through pressing and other processes to form a circuit board with FPC characteristics and PCB characteristics. [0003] At present, some rigid-flex boards on the market are static flexures (that is, customers only have flexure requirements during installation), and the cost of using high-flexibility flexible board materials is relatively high, while ordinary FR4 materials cannot meet the flexure requirements. How to solve the above problems is an imminent problem before us. Contents of the invention [0004] In order t...
