Abstract
The invention relates to a steel mesh structure for solder paste three-dimensional printing. The steel mesh structure comprises a steel mesh body, wherein installation bars are arranged at the two ends of the steel mesh body, positioning row bores are formed in the installation bars, the steel mesh body comprises flat areas, ribs are arranged on the surface of each flat area at intervals, through steel mesh openings are formed in each flat area, first clearance bosses are arranged on the ribs at the positions of the steel mesh openings, second clearance bosses are arranged on the opposite side of the first clearance bosses, and the minimum spacing a between each first clearance boss and the corresponding steel mesh opening is 0.22 mm. By the adoption of the ribs and the two rows of clearance bosses, interference in printing of other elements is effectively and completely avoided, and production efficiency is improved.
Description
Technical field
The present invention relates to printed circuit and manufacture field, the steel mesh of particularly tin cream stereosopic printing.
Background technology
Along with developing rapidly of electron trade, electronic product is various in style, and precise electronic components and parts are widely used and industry-by-industry, requires higher to the quality of precise electronic components and parts and yields simultaneously.The quality of the SMT of pcb board directly affects its working (machining) efficiency, yields of producing, and the quality of SMT and printed steel mesh closely bound up, so the structural design of printed steel mesh is extremely important.Printed steel mesh is used to the mould of print solder paste, is leaked and is taped against on pcb board pad, namely print on pcb board pad by steel mesh opening size, then cross stove during print solder paste by steel mesh opening.The mode that the two-sided processing procedure of current SMT print tin generally adopts first produces one side, regenerative ratio another side after backflow.Most of steel mesh is all adopt common plane steel mesh, counts differ greatly because of pcb board two sides, and the connector on pcb board pad, directly impact uses plane steel mesh to the printing of other elements, affects production efficiency.
Summary of the invention
The applicant, for the above-mentioned shortcoming of prior art, carries out studying and improving, and provides a kind of tin cream stereosopic printing steel net structure, its reasonable in design, use reliable, stability is high.
In order to solve the problem, the present invention adopts following scheme:
A kind of tin cream stereosopic printing steel net structure, comprise steel mesh body, the two ends of described steel mesh body are provided with mounting bar, and mounting bar is provided with location round; Steel mesh body comprises clear area, the surface of clear area is provided with spaced apart raised line, clear area is provided with the steel mesh opening run through, described raised line in steel mesh opening place is provided with first and keeps away a boss, be positioned at the first offside keeping away a boss to be provided with second and to keep away a boss, the first minimum spacing a keeping away a boss and steel mesh opening is 0.22mm.
Technique effect of the present invention is:
The present invention adopts raised line, doublely keeps away a boss structure, effectively completely avoid the interference to other element print, enhances productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged drawing in A portion in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As depicted in figs. 1 and 2, the tin cream stereosopic printing steel net structure of the present embodiment, comprises steel mesh body 1, and the two ends of steel mesh body 1 are provided with mounting bar 2, and mounting bar 2 is provided with location round 3; Steel mesh body 1 comprises clear area 4, the surface of clear area 4 is provided with spaced apart raised line 5, clear area 4 is provided with the steel mesh opening 6 run through, and the raised line 5 in steel mesh opening 6 place is provided with first and keeps away a boss 7, is positioned at the first offside keeping away a boss 7 and is provided with second and keeps away a boss 8.
In the present invention, the first minimum spacing a keeping away a boss 7 and steel mesh opening 6 is 0.22mm; Practice shows, when minimum spacing a is 0.22mm, saves space while ensureing to keep away an effect.
Above illustrated embodiment is better embodiment of the present invention, only be used for conveniently the present invention being described, not any pro forma restriction is done to the present invention, have in any art and usually know the knowledgeable, if do not depart from the present invention carry in the scope of technical characteristic, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and do not depart from technical characteristic content of the present invention, all still belong in the scope of the technology of the present invention feature.
