Problems solved by technology

[0003] The existing method of making the joint of the soft-rigid board is to first press and then remove the edge and form it. This method is easy to cause damage to the soft board when the edge is removed, and it is easy to peel off the hard board in the window area of ​​the soft board. It causes burrs and edging, which causes a high defect rate in the subsequent production process, and the junction of the rigid-flex board produced by the existing method is prone to open circuits

Abstract

The invention discloses a manufacture method of a joint part of a hard-and-soft combined plate. The manufacture method includes the following steps: a punching a seam on the hard-and-soft joint part on a hard plate; b attaching, pressing and curing a polyimide film on the combined surface of the hard plate and a soft plate; c compositing the hard plate and the soft plate to complete assembling of the hard-and-soft combined plate, wherein the bonding materials are needed to punch a window opening position of the soft plate in advance; d sequentially performing drilling, copper plating, line manufacture and solder mask manufacture on the hard-and-soft combined plate obtained in the step c; e producing the contour at the window opening position of the soft plate in laser cutting or edge milling mode; and f stripping the hard plate base materials at the window opening position of the soft plate. Therefore, the manufacture method can improve the stripping quality of the joint part of the hard-and-soft combined plate, cannot have deckle edge or burrs, cannot damage the soft plate and improves productivity and yield.

Description

technical field [0001] The invention relates to the technical field of rigid-flex boards, in particular to a method for manufacturing a joint portion of a rigid-flex board. Background technique [0002] Rigid-flex board is a new type of printed circuit board that combines the durability of rigid printed circuit board (PCB, printed circuit board) and the adaptability of flexible PCB. The most resistant, so it is favored by medical and military equipment manufacturers, and Chinese companies are gradually increasing the proportion of soft and hard boards in the overall output. [0003] The existing method of making the joint of the soft-rigid board is to first press and then remove the edge and form it. This method is easy to cause damage to the soft board when the edge is removed, and it is easy to peel off the hard board in the window area of ​​the soft board. Burrs and burrs are caused, resulting in a high defect rate in the subsequent manufacturing process, and the junctio...
