Abstract
The utility model relates to a pressing tool for reinforcement of an FPC and PCB combined board. The pressing tool and a product, namely the combined board, are included; a groove matching the shape of the product is formed in the middle of the pressing tool, the thickness of the pressing tool is 1 to 1.5 mm greater than the total thickness of the product, the size of the groove in the pressing tool is 0.03 to 0.1mm greater than that of the product, and the depth of the groove is 0.1 to 0.3mm lower than the total thickness of the product; and the product comprises a FPC layer, a PCB layer, a glue layer and a protective layer, wherein the FPC layer is connected with the PCB layer via the glue layer, the area of the PCB layer is lower than that of the FPC layer, the PCB layer is made of an FR-4 level material, the thickness of the PCB layer is greater than 0.6mm, and the protective layer is arranged at the surface of the FPC layer. Compared with the prior art, the edge of the relatively thick reinforcing material is smooth after cutting, the pressing quality is improved, offset in the product pressing process is effectively avoided, and the product quality is improved.
Description
Technical field
The utility model relates to circuit board fabrication technical field, especially a kind of Rigid Flex reinforcement tool for stitching.
Background technology
The current information age, electronic product is followed the paces in epoch, and variation with rapid changepl. never-ending changes and improvements is occurring.Printed wiring board is applied in electronic product more and more widely, as computer, mobile phone, camera, video camera, Medical Devices etc.The development of industry of printed circuit boards is maked rapid progress, and has the development trend that is transitioned into flexible PCB (FPC) from hardboard (PCB), FPC make circuit board more and more gentlier, more and more thinner, pliability significantly improves.Rigid-flexible circuit board particularly, the supporting role of existing rigid circuit board, have again the characteristic of flexible PCB, so its application is because its significant superiority has prospect more and more widely.
FR-4 is the code name of glass-epoxy copper-clad plate flame resistant material grade, the meaning of representative is resin material must can be from a kind of material specification of horizontal blanking through fired state, it is not a kind of title material, but a kind of material rate is a kind of PCB base material of main flow.FR4 reinforcement is at present bar and pastes or single PCS operation, if bar pastes operation, thicker reinforcement gives die-cut rear product edge smooth not, and producing chip affects product appearance.If single PCS operation because FR4 is thicker, is easily offset when pressing operation, affect product quality.
Utility model content
For above the deficiencies in the prior art, the purpose of this utility model is to provide a kind of reasonable in design, can effectively avoid product pressing skew, improves the Rigid Flex reinforcement tool for stitching of product quality.
The purpose of this utility model is achieved by the following technical solution:
Rigid Flex reinforcement tool for stitching, comprises tool for stitching and product, has the groove matching with shape of product, the large 1mm-1.5mm of described tool for stitching Thickness Ratio product gross thickness in the middle of described tool for stitching.
As optimal technical scheme of the present utility model, the groove on described tool for stitching is than the large 0.03mm-0.1mm of product size.
As optimal technical scheme of the present utility model, described depth of groove is than the little 0.1-0.3mm of product gross thickness.
As optimal technical scheme of the present utility model, described product comprises soft board layer, hardboard layer and glue-line, and described soft board layer is connected by glue-line with hardboard layer, and the long-pending soft board aspect that is less than of described hardboard aspect is amassed.
As optimal technical scheme of the present utility model, described hardboard layer material is FR4, and thickness is greater than 0.6mm.
As optimal technical scheme of the present utility model, described product also comprises protective layer, and protective layer is located at soft board layer surface.
The beneficial effects of the utility model are: with respect to prior art, the utility model is reasonable in design, and the smooth of the edge of thicker supporting material after die-cut improved the quality of pressing operation, effectively avoid the shift phenomenon producing in product pressing process, improved the quality of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, tool for stitching, 2, groove.
Embodiment
The existing accompanying drawings of concrete structure of the present utility model and embodiment is as follows:
As shown in Figure 1, Rigid Flex reinforcement tool for stitching, comprises tool for stitching and product, in the middle of described tool for stitching 1, has the groove 2 matching with shape of product, the large 1mm-1.5mm of described tool for stitching Thickness Ratio product gross thickness.
In the present embodiment, described tool for stitching upper groove 2 sizes are than the large 0.03mm-0.1mm of product size; The little 0.1mm-0.3mm of groove 2 depth ratio product gross thickness; Described in the present embodiment, product comprises soft board layer, hardboard layer and glue-line, and described soft board layer is connected by glue-line with hardboard layer, and the long-pending soft board aspect that is less than of hardboard aspect is amassed.Described product hardboard layer material is FR4, and thickness is greater than 0.6mm.Described in the present embodiment, product also comprises protective layer, and protective layer is located at soft board layer surface.In work, by putting into fast press together with the auxiliary material of tool for stitching, product and pressing, carry out pressing operation, after pressing, product is taken out, tool for stitching can be reused.
