Abstract
The invention discloses an improved prepreg glue presoaking device used for PCB (Printed circuit board) production, which comprises a glue groove, at least two presoaking rolls and a frictioning rod, wherein a glue solution is contained in the glue groove; the presoaking rolls are assembled in the glue groove and soaked in the glue solution; and glass fiber cloth is wound on the presoaking rolls to be conveyed. According to the improved prepreg glue presoaking device, the presoaking rolls are arranged in the glue solution, and the glass fiber cloth is wholly soaked in the glue solution when wound on the presoaking rolls, so that the soaking time and a soaking area are increased; both sides of the glass fiber cloth can be in contact with the glue solution directly, so that the gluing uniformity and the permeability of the glass fiber glass fiber cloth are improved; and the function of speed increasing can be achieved due to the increased soaking time.
Description
Technical field
The present invention relates to copper-clad plate industry prepreg process units, be specifically related to a kind of pre-gumming device of modified prepreg produced for pcb board.
Background technology
In copper-clad plate production process, prepreg needs, through pre-impregnation step, glue to be penetrated in glass-fiber-fabric.With reference to Fig. 1, existing pre-soaking system and test is back of the body painting formula system, mainly through preimpregnation roller 2 rotating band gluing inside glue groove 1, then glass-fiber-fabric 3 under the effect of delivery wheel 4 horizontally through preimpregnation roller 2, both tangent contacts (i.e. linear contact lay), glass-fiber-fabric 3 one side contacts gluing with preimpregnation roller 2, and the glass-fiber-fabric 3 after gluing is caught up with gas through frictioning bar 5 again and reaches the effect that glue penetrates into glass-fiber-fabric 3.Above-mentioned pre-soaking system and test is owing to being that the one side of glass-fiber-fabric 3 is by contacting gluing with preimpregnation roller 2, its limitation is had: the transporting velocity of glass-fiber-fabric 3 need be limited in lower scope in permeability and production efficiency, production efficiency is low, and the glue of one side is difficult to uniformly penetrating in glass-fiber-fabric 3, makes product easily occur the problems such as be full of cracks.
Summary of the invention
In order to the production efficiency solving the existence of existing back of the body painting formula pre-soaking system and test is low and the problem of poor permeability, the object of the present invention is to provide a kind of pre-gumming device of modified prepreg produced for pcb board, effectively can improve the problems referred to above, improve production efficiency and product quality.
The technical solution adopted in the present invention is:
A kind of pre-gumming device of modified prepreg produced for pcb board, comprise glue groove, preimpregnation roller and frictioning bar, glue groove is built with glue, and described preimpregnation roller is provided with at least two, preimpregnation roller to be installed in glue groove and to be immersed in glue, and described glass-fiber-fabric is carried on preimpregnation roller.
As the further improvement of technique scheme, in described glue groove, be provided with three preimpregnation rollers.
As the further improvement of technique scheme, described glue groove is set to dovetail groove wide at the top and narrow at the bottom.
The invention has the beneficial effects as follows:
Contrast prior art, the pre-gumming device of modified prepreg of the present invention is arranged on preimpregnation roller in glue, glass-fiber-fabric is all immersed in glue when walking around preimpregnation roller, increase infiltrating time and increase wetted area, because glass-fiber-fabric two sides all can directly contact with glue, therefore the uniformity of glass-fiber-fabric gluing, permeability all improve, and simultaneously because soak time increases, can reach the effect of speed-raising.
After adopting the pre-gumming device of modified prepreg of the present invention to carry out pre-impregnation to glass-fiber-fabric, in follow-up PCB making sheet, also can bring following benefit: one is the generation reducing CAF to a certain extent, the Ion transfer particularly caused due to non-wetting; Two is that infiltrating raising can make glue better penetrate in glass-fiber-fabric, increases the adhesion of glue and glass-fiber-fabric, thus can prevent be full of cracks to a certain extent.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the structural representation of the pre-soaking system and test of existing back of the body painting formula;
Fig. 2 is the structural representation of the pre-gumming device of modified prepreg of the present invention.
Drawing reference numeral illustrates: 1, glue groove; 2, preimpregnation roller; 3, glass-fiber-fabric; 4, delivery wheel; 5, frictioning bar.
Detailed description of the invention
With reference to Fig. 2, preferred embodiment provided by the invention, a kind of pre-gumming device of modified prepreg produced for pcb board, comprises glue groove 1, preimpregnation roller 2 and frictioning bar 5.Glue groove 1 is preferably dovetail groove wide at the top and narrow at the bottom, and glue groove 1 is built with glue.Three preimpregnation rollers parallel to each other between two, 2, three preimpregnation roller 2 rotating Vortexes are provided with for carrying glass-fiber-fabric 3 in glue groove 1.Preimpregnation roller 2 is immersed in glue, and glass-fiber-fabric 3 is around on preimpregnation roller 2, and glass-fiber-fabric 3 is by being also all immersed in glue during preimpregnation roller 2.After glass-fiber-fabric 3 passes glue groove 1, then catch up with gas through frictioning bar 5 and reach the effect that glue penetrates into glass-fiber-fabric 3.
Further, in order to specify out the size of frictioning accurately when subsequent technique is formulated, also dial can be increased at frictioning bar 5 place.The quality of frictioning can affect the effect of catching up with bubble, catches up with gas effect to have impact to permeability.
Further, in order to increase the soak time of glass-fiber-fabric 3, can the width of corresponding increase glue groove 1.
Contrast prior art, the pre-gumming device of modified prepreg of the present invention is arranged on preimpregnation roller 2 in glue, glass-fiber-fabric 3 is all immersed in glue when walking around preimpregnation roller 2, increase infiltrating time and increase wetted area, because glass-fiber-fabric 3 two sides all can directly contact with glue, therefore the uniformity of glass-fiber-fabric 3 gluing, permeability all improve, and simultaneously because soak time increases, can reach the effect of speed-raising.
After adopting the pre-gumming device of modified prepreg of the present invention to carry out pre-impregnation to glass-fiber-fabric, in follow-up PCB making sheet, also can bring following benefit: one is the generation reducing CAF to a certain extent, the Ion transfer particularly caused due to non-wetting; Two is that infiltrating raising can make glue better penetrate in glass-fiber-fabric, increases the adhesion of glue and glass-fiber-fabric, thus can prevent be full of cracks to a certain extent.
Above concrete structure and sized data illustrate preferred embodiment of the present invention, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replacement are all included in the application's claim limited range.
