Abstract

A printed circuit board and a manufacturing method thereof are provided to improve quality or performance of a product by minimizing deformation by heat while a part such as a camera module and et cetera is being mounted. A printed circuit board includes an internal layer (100), an external insulation layer and an external core layer. The internal layer is made of a flexible circuit board. The external insulation layer is laminated on more than one layer of one or the other layer. The external core layer is laminated on the external insulation layer and includes a reinforcement layer made of a rigid material of which strength is greater than the internal layer and external layer. The second external core layer includes a second reinforcement layer and a second external circuit layer. The first reinforcement layer and the second reinforcement layer are made of at least one material among FR-4, HI-tg or BT.

Description

technical field [0001] The invention relates to a printed circuit substrate and its manufacturing method, especially a printed circuit substrate with rigid material added to maintain flatness when installing a camera module and its manufacturing method. Background technique [0002] figure 1 It is a cross-sectional structural view of a conventional printed circuit board. Such as figure 1 As shown, the printed circuit substrate 1 of the prior art includes an upper base layer 2 and a lower base layer 3, and the upper base layer 2 and the lower base layer 3 are bonded together by an adhesive film 4; The first insulating layer film 2a on the side and the first copper foil layer 2b for forming circuit patterns that are thermally pressed on the first insulating layer film 2a; the lower base layer 3 includes the second layer laminated on the other side of the adhesive film 4 The insulating layer film 3a and the second insulating layer film 3b are thermally pressed on the outside...
