Abstract
A preparation method for a rigid-flexible printed circuit board involves initially providing a flexible board, divided into two regions along its extension direction. A first protective layer is applied to the flexible board, with distinct parts covering the two regions respectively. Subsequently, a rigid board is positioned in the second region, designed with a notch to alleviate height discrepancies introduced by the protective layer. The final step involves laminating the rigid board to the flexible board. This ensures the portion of the rigid board adjacent to the second portion is aligned flush with the rest, resulting in a rigid-flex PCB with improved flatness. This method is particularly significant for applications requiring precise structural integrity and consistency in electronic devices.
