Abstract
The invention is suitable for the field of solder paste printing, and provides a convex steel mesh and a manufacturing method thereof, and a solder paste printer. The convex steel mesh is provided with a laser steel mesh, wherein the laser steel mesh is provided with a plurality of openings which are covered and sealed by a convex steel cap. The convex steel mesh is formed by covering and sealing the openings of the common laser steel mesh through the convex steel cap, has a short manufacturing period and low cost, can replace an electrocast convex steel mesh and is applied to the solder paste printing condition with a local protection requirement, and the effect and service life of the convex steel mesh are equivalent to those of the electrocast convex steel mesh.
Description
Technical field
The invention belongs to paste solder printing field, relate in particular to a kind of convex steel mesh and preparation method thereof and stencil printer.
Background technology
In Electronic Assemblies, because of the application requirements of some specialities, printing need to be done local eminence with steel mesh, to protect the element in it.The steel mesh that surpasses 0.2mm for bump height, industry is all to make by electroforming process.The fabrication cycle of electroforming steel mesh is one to surrounding, and cost is about ten times of common laser steel mesh, and mostly need be from external making buying, and procurement cycle is about one month.Fabrication cycle length and cost height have greatly limited the application of electroforming convex steel mesh.
Summary of the invention
The object of the embodiment of the present invention is to provide a kind of convex steel mesh, is intended to solve existing electroforming convex steel mesh fabrication cycle long, the problem that cost is high.
The embodiment of the present invention is achieved in that a kind of convex steel mesh, has a laser steel mesh, and described laser steel mesh is provided with a plurality of openings, and described opening covers sealing by convex steel cap; The sidewall slope of described convex steel cap, with the angle of horizontal plane be 120～140 °
Another object of the embodiment of the present invention is to provide a kind of stencil printer, and described stencil printer has above-mentioned convex steel mesh.
Another object of the embodiment of the present invention is to provide a kind of preparation method of convex steel mesh, said method comprising the steps of:
Get laser steel mesh, in described laser steel mesh, a plurality of openings are set;
Get convex steel cap, with described convex steel cap, cover the described opening of sealing;
Wherein, the sidewall slope of described convex steel cap, with the angle of horizontal plane be 120～140 °.
The opening that the embodiment of the present invention covers sealing common laser steel mesh by convex steel cap is made convex steel mesh, and fabrication cycle is short, and cost is low, and effect and service life thereof are suitable with electroforming convex steel mesh.The alternative electroforming convex steel mesh of this convex steel mesh, is applied to the paste solder printing situation of localised protection requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of the convex steel mesh that provides of the embodiment of the present invention.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The embodiment of the present invention is made convex protuberance on common laser steel mesh, and to substitute electroforming convex steel mesh, fabrication cycle is short, and cost is low, and effect and service life thereof are suitable with electroforming convex steel mesh.
The convex steel mesh that the embodiment of the present invention provides has a laser steel mesh, and described laser steel mesh is provided with a plurality of openings, and described opening covers sealing by convex steel cap.
The stencil printer that the embodiment of the present invention provides has above-mentioned convex steel mesh.
The preparation method of the convex steel mesh that the embodiment of the present invention provides comprises the following steps:
Get laser steel mesh, in described laser steel mesh, a plurality of openings are set;
Get convex steel cap, with described convex steel cap, cover the described opening of sealing.
As shown in Figure 1, the convex steel mesh that the embodiment of the present invention provides adopts common laser steel mesh 1 for raw material, and laser steel mesh 1 is provided with a plurality of openings 2 (two openings are only shown in figure) for this reason, and this opening 2 is made generally in square or rectangle, so that processing.Each opening 2 covers sealing by convex steel cap 3 and forms convex and swell, sidewall 31 inclinations of convex steel cap 3, with the angle of horizontal plane be 120～140 °, be beneficial to tin cream and come off.The side of this convex steel cap 3 is trapezoidal.
In embodiments of the present invention, convex steel cap 3 welds by argon arc welding or glue is adhesively fixed in laser steel mesh 1.Because of laser steel mesh 1 thinner (being about 0.1mm), in use scraper scrapes back and forth and can produce wriggle, and easily causes solder joint between convex steel cap 3 and laser steel mesh 1 to come off or bonded adhesives comes unstuck.For this reason, especially at above-mentioned opening 2, be circumferentially provided with the flanging 11 that the sloped sidewall 31 with convex steel cap 3 fits, the height of the height of this flanging 11 and convex steel cap sloped sidewall 31 is suitable, strengthened local stiffness, avoid solder joint or viscose glue position to produce Joint failure because of wriggling, extend the service life of convex steel mesh, be even longer than electroforming convex steel mesh its service life.
In the embodiment of the present invention, convex steel cap 3 is formed by metal derby machining; Also can be by sheet metal punching press or bending forming.This convex steel cap 3 is easy to machine-shaping, and speed is fast, and cost is low.Adopt common laser steel mesh 1 as primary raw material simultaneously, thereby the cost of this convex steel mesh is reduced greatly, be about 1/10th of electroforming convex steel mesh.In addition, the fabrication cycle of this convex steel mesh is about one day, compared with electroforming convex steel mesh, greatly shortens, and is also beneficial to and reduces costs.
The embodiment of the present invention also provides a kind of stencil printer with above-mentioned convex steel mesh.
The opening that the embodiment of the present invention covers sealing common laser steel mesh by convex steel cap is made convex steel mesh, and fabrication cycle is short, and cost is low, and effect and service life thereof are suitable with electroforming convex steel mesh.Meanwhile, the opening that convex protuberance covers sealed laser steel mesh by a convex steel cap forms, and the cross section of convex steel cap is designed to trapezoidal shape, is beneficial to tin cream and comes off.In addition, above-mentioned opening be circumferentially provided with the flanging that the sloped sidewall with convex steel cap fits, strengthened local stiffness, avoid solder joint or viscose glue position because wriggling produces Joint failure, extend the service life of convex steel mesh.Therefore, this convex steel mesh can substitute electroforming convex steel mesh, is applied to the paste solder printing situation of localised protection requirement.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
