Description
Technical field
The invention discloses a kind of manufacture method of printed substrate, the present invention especially relates to a kind of manufacture method of Rigid Flex.
Background technology
At present, along with consumer electronics product multifunction, lightening, integrated development trend, its printed circuit board (PCB) aligning accuracy is required and product ageing more and more higher.In current rigid-flex, soft board carries out (being called for short the front moulding of soft board) before being molded over rigid-flex pressing, and the method moulding has following shortcoming:
(1), destroy the integrality of soft board, affect the dimensional stability of rigid-flex, increase contraposition difficulty between layers;
(2), soft board need separate and carry out when doing some identical surface treatments with hardboard, the prolongation production time;
(3), soft board could make need obtain soft board harmomegathus while using mould stamp mode time, prolongation production is consuming time.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of process variation that can reduce can shorten the manufacture method of a kind of Rigid Flex of production time again.
According to technical scheme provided by the invention, the manufacture method of described a kind of Rigid Flex comprises the following steps:
A, in the upper and lower surface of commercially available soft board substrate 1, all make line pattern and stick coverlay 2, on a surface of commercially available hardboard semi-finished product 3, make line pattern;
B, on upper and lower two coverlay 2 surfaces equal superimposed prepreg 4 and hardboard semi-finished product 3 that dragged for window, soft board substrate 1, coverlay 2, prepreg 4 and hardboard semi-finished product 3 are pressed together, make to make the surface of hardboard semi-finished product 3 of line pattern towards soft board substrate 1, obtain Rigid Flex blank;
C, by holing and electroplating the hardboard semi-finished product 3 in Rigid Flex blank and 1 conducting of soft board substrate, on another surface of hardboard semi-finished product 3, make line pattern, obtain Rigid Flex crude product;
D, the upper and lower surface of Rigid Flex crude product all print every weldering ink layer 5, soft or hard at Rigid Flex crude product is dragged for type processing in conjunction with waste material limit, again the soft or hard of Rigid Flex crude product is carried out to radium-shine cutting in conjunction with non-waste material limit, make the degree of depth of line of cut arrive the surface of this side coverlay 2, by taking off lid, coverlay 2 is exposed, obtain Rigid Flex semi-finished product;
E, Rigid Flex semi-finished product are carried out to surface treatment, obtain Rigid Flex sheet material;
F, Rigid Flex sheet material is cut into Rigid Flex bulk;
G, by having been taken off the soft board that exposes of lid on Rigid Flex bulk, partly use the moulding of mould stamp mode.
The thickness of described soft board substrate is 0.049 ~ 0.70mm.
The thickness of described coverlay is 0.0280 ~ 0.0610mm.
The half-finished thickness of described hardboard is 0.500 ~ 1.600mm.
The thickness of described prepreg is 0.025 ~ 0.075mm mm.
The described thickness every weldering ink layer is 0.0101 ~ 0.0305mm.
In step b, pressure force when soft board substrate, coverlay, prepreg and hardboard semi-finished product press together is controlled at 2.6 ~ 2.8MPa.
The present invention can guarantee the integrality of plank size in process of production greatly, can guarantee that again soft board and hardboard carry out surface treatment simultaneously, have reduced process variation and have shortened the production time again.
