Abstract

The invention provides a fabrication method for a rigid-flex printed combination board of a covering membrane window. The fabrication method comprises the steps of soft board treatment, hard board treatment and treatment after a soft board and a hard board are combined, wherein the step of soft board treatment comprising surface roughening, in which the surface of the soft board is roughened; lamination for a first time, in which a covering membrane is pressed onto the surface of the soft board; soft board appearance, in which the appearance of the soft board is subjected to shaping; and soft board roughening, in which the soft board after being subjected to shaping is roughened; the step of hard board treatment comprises inner layer etching; mechanical groove carving for the first time, in which grooves are carved on the part of a flexible region of the hard board; and blackening, in which the surface roughness of copper foils at an inner layer is enhanced; and the step of treatment after the soft board and the hard board are combined comprises lamination for a second time, in which the roughened soft board and the blackened hard board are laminated to form the soft and hard combination board. Lamination is performed for twice in the fabrication method, the lamination reliability and the fabrication yield can be improved, and plasma treatment is adopted prior to copper deposition, the reliability of a hole wall can be ensured.

Description

technical field [0001] The invention relates to a manufacturing process of a printed circuit board (PCB), in particular to a manufacturing method of a rigid-flex printed combined board with a cover film opening a window. Background technique [0002] In some specific fields, it is difficult for ordinary rigid PCBs to meet the special assembly requirements of products. Rigid-flex boards are being used more and more widely due to their excellent three-dimensional flexibility. Rigid-flex printed board refers to a printed board containing one or more rigid areas and one or more flexible areas, which is composed of rigid boards and flexible boards laminated together in an orderly manner, and formed with metallized holes Electrical connections. [0003] With the development of electronic products in the direction of high density, miniaturization, and high reliability, rigid-flexible printed circuit boards are especially suitable for today's electronic products for light, Require...
