Abstract
The utility model relates to a device for improving the wettability of a prepreg. The device comprises a big trapezoid open slot (1) and a small trapezoidal groove (9) with a downward opening, wherein, glue (3) is arranged in the big trapezoid open slot (1); no power turning rolls (4) are respectively arranged on both sides of the small trapezoidal groove (9) with the downward opening; the lower end of the small trapezoidal groove (9) is in contact with the liquid level of the glue (3); a group of grid pieces (5) are fixedly arranged in the small trapezoidal groove (9); the bottoms of the grid pieces (5) and the groove mouth of the small trapezoidal groove (9) are on the same plane; an evacuation port (7) connected with a vacuum pump is also formed on the upper part of the small trapezoidal groove (9); and an opening (8) which can be used for adjusting the negative pressure is also formed on the small trapezoidal groove (9). The device for improving the wettability of the prepreg has the benefits of improving the presoaking manner of reinforcing materials and enhancing the wettability of the glue and the reinforcing materials.
Description
Technical field
The utility model relates to a kind of prepreg that the copper-clad plate manufacturing of electron trade basic material and PCB use in making that is applied to, and especially refers to improve the infiltrating device of prepreg.
Background technology
Prepreg is the semi-finished product in the copper coated plate manufacturing process, by reinforcing material being soaked into resin glue, and then obtains through oven drying.In the production process of prepreg, usually will be for obtaining good effect of impregnation may through preimpregnation and the main immersing glue process that soaks twice.Because gluing machine is running fast continuously, the contact time of reinforcing material and glue is extremely short, and glue can't fully soak into reinforcing material at short notice.Often residual a large amount of small gases in the reinforcing material form easily in follow-up copper-clad plate compacting or the PCB multilayer pressing process and hidden danger of quality occurs, the slight product quality that influences, the serious product rejection that causes.
Summary of the invention
The utility model technical issues that need to address have provided a kind of infiltrating device of prepreg that improves, and are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: big trapezoid-shaped openings groove; In described big trapezoid-shaped openings groove, glue is arranged; The little dovetail groove that Open Side Down; Settle unpowered slewing rollers respectively in described little dovetail groove two sides that Open Side Down; The lower end of little dovetail groove and the liquid level of glue contact; Go back one group of grid sheet of fixed in position in described little dovetail groove, the bottom of grid sheet and the notch of little dovetail groove are on same horizontal plane; Also settle a vacuum orifice that links to each other with vavuum pump on the top of little dovetail groove, on little dovetail groove, also settle an opening that can be used for regulating negative pressure value.
Compared with prior art, the beneficial effects of the utility model are: reinforcing material preimpregnation mode is improved, improved the wettability between glue and reinforcing material.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 1: the utility model comprises: big trapezoid-shaped openings groove 1; In described big trapezoid-shaped openings groove 1, glue 3 is arranged; The little dovetail groove 9 that Open Side Down; Settle unpowered slewing rollers 4 respectively in described little dovetail groove 9 two sides that Open Side Down; The liquid level of the lower end of little dovetail groove 9 and glue 3 contacts; Go back one group of grid sheet 5 of fixed in position in described little dovetail groove 9, the notch of the bottom of grid sheet 5 and little dovetail groove 9 is on same horizontal plane; Also settle a vacuum orifice that links to each other with vavuum pump 7 on the top of little dovetail groove 9, on little dovetail groove 9, also settle an opening 8 that can be used for regulating negative pressure value;
The side of described big trapezoid-shaped openings groove 1 other also settle one with return the overflow launder 2 that plastic pipe links to each other.
The utility model is transformed into the device that can obtain the fluid-tight cavity with original uncovered pre-immersion trough.The top of cavity is connected with a vavuum pump, because there is certain negative pressure in the effect of vavuum pump in the cavity of pre-immersion trough top, at reinforcing material through the out-of-date discharge that helps gas in the reinforcing material, glue occupies the position of reinforcing material inner air vent rapidly, reaches to improve the effect of soaking into.
Adopt embody in the use of prepreg that the utility model produces and prepreg following some:
Remaining pore obviously reduces in the prepreg, compares pore with the prepreg of common mode production and reduces more than 95%.
The prepreg smooth surface, gluing is even.
Because of the prepreg wettability is good, in the manufacturing of copper-clad plate, be difficult for producing gummosis, the defective that no weavy grain appears produces.
In the reinforcing material, pore class microdefect reduces, and the reliability of sheet material improves.
Adopt the course of work of the present utility model to be: reinforcing material 6 passes slewing rollers 4 from the right side of this device along the direction of arrow, and reinforcing material tangent plane under slewing rollers contacts with glue 3 liquid levels.Between two slewing rollers, the opening of little dovetail groove 9 is immersed in below the liquid level, forms a closed cavity.Vavuum pump continues emptying gas outward by vacuum orifice 7, makes and forms certain negative pressure in the cavity.After reinforcing material immersed glue, glue infiltrated in the reinforcing material, and the original simultaneously air in reinforcing material is discharged from.Because exist certain negative pressure, this process to obtain quickening, strengthening above glue between the slewing rollers, the small gas in the reinforcing material is forced to rapidly, extracts out fully, glue soaks into reinforcing material rapidly, and the wettability that finally shows as reinforcing material improves.
The utility model is simple in structure, can be used for the needs of different liquid resin preimpregnation, and reinforcing material can be applicable to simultaneously: glass cloth, glass fibre non-woven, insulating paper etc.
Claims (2)
1. one kind is improved the infiltrating device of prepreg, comprising: big trapezoid-shaped openings groove (1); In described big trapezoid-shaped openings groove (1), glue 3 is arranged; It is characterized in that also comprising: the little dovetail groove (9) that Open Side Down; Settle unpowered slewing rollers (4) respectively in the described little dovetail groove that Open Side Down (9) two sides; The liquid level of the lower end of little dovetail groove (9) and glue (3) contacts; Go back one group of grid sheet of fixed in position (5) in described little dovetail groove (9), the notch of the bottom of grid sheet (5) and little dovetail groove (9) is on same horizontal plane; Also settle a vacuum orifice that links to each other with vavuum pump (7) on the top of little dovetail groove (9), on little dovetail groove (9), also settle an opening (8) that can be used for regulating negative pressure value.
