Abstract
The utility model relates to a threaded support column for a circuit board. The threaded support column comprises a column-shaped adsorption part and a column-shaped surface-mounting part which axially extends out from one end of the adsorption part, wherein the diameter of the surface-mounting part is smaller than that of the adsorption part. The threaded support column is axially provided with a first threaded hole towards the inside from the surface of one end at which the adsorption part is positioned, and a second threaded hole towards the inside from the surface of one end at which the surface-mounting part is positioned, wherein both the first threaded hole and the second threaded hole extend towards the middle of the threaded support column and are not communicated with each other. The threaded holes of the threaded support column are blind holes; and when an SMT (surface mount technology) is used for surface mounting, a chip mounter only needs to be adsorbed on the adsorption part and the surface-mounting part is inserted in a positioning hole which is pre-arranged in the circuit board. The threaded support column does not need to be pre-covered with a cover plate, the follow-up removal of the cover plate is not needed either, therefore the troubles of covering and removing of the cover plate can be avoided, the production efficiency can be improved, and meanwhile the damages to the circuit board and the threaded support column which are caused by the removal of the cover plate are avoided.
Description
Technical field
The utility model relates to the circuit board that a kind of SMT of being applicable to technology mounts and uses the screw thread support column
Background technology
are the abbreviations of surface installation technique or surface mounting technology Surface Mounted Technology; Be most popular a kind of technology or technology in the present electronics assembling industry, it is the assigned address that utilizes pull of vacuum that workpiece absorption is mounted on to be pasted the space of a whole page through chip mounter.The SMT technology has advantages such as paster speed is fast, accurate positioning.
Generally all the screw thread support column can be set on
circuit board, another piece circuit board etc. that makes top object relatively can be so as to separating with circuit board, and combine with screw.These screw thread support columns mount on the circuit board through the SMT technology.The wiring board of prior art generally all is in the middle of cylinder, to offer the screwed through hole that runs through up and down with the screw thread support column.Mount in the process at SMT; At first must the cover plate that through hole is covered be set at an end of the cylinder of screw thread support column; Mount in the time of need another piece circuit board being realized the screw thread close-fitting of two circuit boards through double-screw bolt after the completion; Also want artificial and cover plate is removed this not only time-consuming taking a lot of work, also fragile double-screw bolt and circuit board
Summary of the invention
the utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of improved circuit board to use the screw thread support column, so that SMT mounts.
For solving above technical problem, the utility model is taked following technical scheme:
a kind of circuit board is used the screw thread support column, comprises that the adsorption section of cylindricality and the cylindricality that the end from said adsorption section extends axially out mount portion, and the said diameter that mounts the diameter of portion less than said adsorption section; Said screw thread support column has inwardly been offered first screwed hole vertically from the end face of place, said adsorption section end; Said screw thread support column has inwardly been offered second screwed hole vertically from the end face of the said portion of mounting place end, and said first screwed hole and said second screwed hole all extend and not connected to the middle part of said screw thread support column.
preferably, said second screwed hole runs through said and mounts portion and extend in the said adsorption section.
preferably, said adsorption section is coaxial with the said portion that mounts.
preferably, said first screwed hole is coaxial with said second screwed hole.
preferably, the said length that mounts portion is 1/6 ~ 1/4 of said adsorption section length.
preferably, the said outer wall that mounts portion is provided with many perpendicular lines.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
the utility model circuit board is used the screw thread support column, because screwed hole is a blind hole, does not connect whole double-screw bolt, only need hold the adsorption section during chip mounter vacuum suction, the portion of mounting is inserted to be opened in advance in the location hole on the circuit board get final product.Do not need on double-screw bolt, to add a cover in advance cover plate like this and be convenient to inhale vacuum to block screwed hole; Follow-uply need not remove cover plate yet; Therefore can save the operation of adding a cover in the prior art and removing cover plate, enhance productivity, when also having avoided removing cover plate simultaneously to the damage of circuit board and double-screw bolt.
Description of drawings
Below in conjunction with accompanying drawing and concrete execution mode the utility model is done further detailed explanation:
Fig. 1 is the stereogram of the utility model screw thread support column;
Fig. 2 is the main cutaway view of the utility model screw thread support column;
Fig. 3 is the vertical view of the utility model screw thread support column;
wherein: 1, adsorption section; 2, mount portion; 20, perpendicular line; 3, first screwed hole; 4, second screwed hole.
Embodiment
are referring to Fig. 1 ~ 3; The cylindricality that the circuit board of present embodiment comprises the adsorption section 1 of cylindricality with the screw thread support column and an end of 1 extends axially out from the adsorption section mounts portion 2; And mount the diameter of the diameter of portion 2 less than adsorption section 1, the length that mounts portion 2 is about 1/5 of adsorption section 1 length.1 from adsorption section end face at one end of this screw thread support column has inwardly been offered first screwed hole 3 vertically; 2 end faces have at one end inwardly been offered second screwed hole 4 vertically from the portion of mounting, and first screwed hole 3 and second screwed hole 4 all extend and not connected to the middle part of this screw thread support column.Therefore, the screwed hole of present embodiment is a blind hole.
In
present embodiment, the length that mounts portion is shorter, and second screwed hole 4 runs through whole and mounts portion 2 and extend in the adsorption section 1; According to the actual design needs, the degree of depth of first screwed hole 3 and second screwed hole 4 is roughly the same, and adsorption section 1, to mount portion 2, first screwed hole 3 and second screwed hole 4 four coaxial.
mount more jail of the welding of rear thread support column on circuit board for making, and the outer wall that present embodiment mounts portion 2 is provided with many perpendicular lines 20, more to help scolding tin.
present embodiment screw thread support column is because screwed hole is a blind hole; When utilizing the SMT technology to mount; Chip mounter directly holds, adsorption section 1, just can the screw thread support column be sucked up, and the portion that mounts 2 with the screw thread support column inserts in the location hole of offering in advance on the circuit board then.Thereby removed the trouble of on double-screw bolt, adding a cover and removing from, improved production efficiency, when having avoided removing cover plate to the damage of circuit board and double-screw bolt.
More than the utility model has been done detailed description; Its purpose is to let the personage that is familiar with this art can understand the content of the utility model and implements; Can not limit the protection range of the utility model with this; All equivalences of doing according to the spirit of the utility model change or modify, and all should be encompassed in the protection range of the utility model
