Method for manufacturing rigid-flexible printed circuit board and the rigid-flexible printed circuit board

摘要

the present invention comprises the steps of making the rigid substrate including a flexible window area; At least one unit of the flexible board comprising the steps of: a flexible internal window area of the rigid substrate; Comprising the steps of: forming at least one build-up layer on one or both sides of the rigid substrate containing the flexible board unit; By removing the portion that covers a flexible region of the flexible board unit from the build-up, and provides a manufacturing method of a rigid-flexible printed circuit board forming a rigid-flexible printed circuit board. The present invention significantly reduces the manufacturing cost of the rigid flexible printed circuit board, it is possible to increase the product yield and reliability of the printed circuit board. ;
