Rigid-flex printed circuit board for sleeving and manufacturing method

Abstract

The invention provides a rigid-flexible printed circuit board for sleeving and a manufacturing method. The rigid-flexible printed circuit board for sleeving comprises a flexible layer, bonding layersand rigid layers; the rigid layers are connected with the upper and lower sides of the flexible layer through the bonding layers; flexible areas and rigid-flexible combination areas are formed on therigid-flexible printed circuit; a plurality of rigid clamping connection positions are arranged between the rigid-flexible combination areas on the two sides at intervals; the clamping connection positions are integrally formed on the rigid layer; the clamping connection positions of the flexible areas on the upper side and the lower side are arranged in a staggered mode, and the clamping connection positions jointly form a clamping supporting structure used for clamping and supporting the flexible layer corresponding to the flexible areas. According to the invention, rigid connection positions are arranged in the flexible areas; flexible connection positions can be prevented from being milled during board splitting; the rigid-flexible printed circuit board for sleeving can be split into single rigid-flexible printed circuit boards simply by adopting a mechanical milling mode; the procedures are few; the board splitting process is simplified; the operation is simple; the cost is low; the problem that the appearance is carbonized and blackened due to the fact that the flexible connection positions are cut by laser is avoided; and the board splitting efficiency and quality are improved.

Description

technical field [0001] The present application belongs to the technical field of circuit boards, and more specifically relates to a rigid-flexible combination board for packaging and a manufacturing method thereof. Background technique [0002] In order to improve the assembly efficiency, when the rigid-flex board is shipped to the component assembly factory, most of the cases are in the form of a set composed of several single pieces. The single piece and the rigid frame of the set are combined through the connection position. These connection positions are generally designed in Rigid area. However, when the flexible area is long, in order to prevent the flexible area from being bent and deformed, which will affect the operation, assembly and / or testing, it is necessary to design a connecting position in the flexible area to connect to the rigid casing frame. After the assembly of the components is completed, the assembly plant needs to divide the package board into indivi...
