The invention provides a kind of shaping of radome and installation method；The material strip of radome is provided；Using silk-screen printing technique by tin cream brush in the default welding region of material strip；Obtained material strip is heated, solidifies tin cream；Stamping process is carried out to the material strip, is molded radome；The radome is positioned on pcb board, the weld for making the tin cream on radome be placed on pcb board；Melt the tin cream；Radome is welded on pcb board.On the welding region for the material strip that tin cream used in welding is pre-set at radome using silk-screen printing technique by the radome shaping of the present invention and installation method, the heat-treated solidification of tin cream, re-melting tin cream when needs are welded, ensure that the activity of tin cream, improves welding performance.And for material strip is compared to pcb board, in the absence of the problem of brush tin scope is small, component stops brush tin, brush tin is convenient, can brush tin scope it is also bigger so that the installation of radome is more convenient.
Description
Technical field
The present invention relates to electronic component technology field, the shaping of more particularly to a kind of radome and installation method.
Background technology
Constantly lifted with the arithmetic speed of electronic installation, given off in electronic installation from electronic component positioned at microwave
The noise intensity of frequency range is growing day by day, not only disturbs other users in the frequency range, is also easier to disturb itself radio frequency receiver.
The outside leakage of noise is suppressed using the gimmick of radome shade to this common solution.
The shaping of existing shield cover and installation method are generally：Punching obtains being molded radome；Printed with steel mesh
Technique brush tin cream on the pad on pcb board；Shield cover is positioned over region of the pcb board provided with tin cream；Pcb board and shield cover
Weld together together after reflow soldering process.If upper radome is not placed after the complete tin cream of the method brush quickly, on pcb board
Tin cream place easily lose activity for a long time in atmosphere, it may occur that the problems such as weldability variation, and when pcb board can brush tin model
Enclose small, or when having component stop, be not easy to carry out brush tin operation, cause various inconvenience.
The content of the invention
The technical problems to be solved by the invention are：The shielding that a kind of welding yield is high, brush tin is convenient and cost is low is provided
The shaping of cover and installation method.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of shaping of radome and installation method；
The material strip of radome is provided；
Using silk-screen printing technique by tin cream brush in the default welding region of material strip；
Obtained material strip is heated, solidifies tin cream；
Stamping process is carried out to the material strip, is molded radome；
The radome is positioned on pcb board, the weld for making the tin cream on radome be placed on pcb board；
Melt the tin cream；
Radome is welded on pcb board.
The beneficial effects of the present invention are：Tin cream used in welding is pre-set at radome using silk-screen printing technique
On the welding region of material strip, the heat-treated solidification of tin cream, re-melting tin cream when needs are welded, the work of tin cream ensure that
Property, improve welding performance.And for material strip is compared to pcb board, in the absence of brush tin scope is small, component stops asking for brush tin
Topic, brush tin are convenient, can brush tin scope it is also bigger so that the installation of radome is more convenient.
Embodiment
To describe the technology contents of the present invention, the objects and the effects in detail, it is explained below in conjunction with embodiment.
The design of most critical of the present invention is：With silk-screen printing technique in advance by tin cream brush in the default welding of the material strip
On region, convenient brush tin and the activity that ensure that tin cream, welding performance is improved.
The invention provides a kind of shaping of radome and installation method；
The material strip of radome is provided；
Using silk-screen printing technique by tin cream brush in the default welding region of material strip；
Obtained material strip is heated, solidifies tin cream；
Stamping process is carried out to the material strip, is molded radome；
The radome is positioned on pcb board, the weld for making the tin cream on radome be placed on pcb board；
Melt the tin cream；
Radome is welded on pcb board.
It was found from foregoing description, the beneficial effects of the present invention are：It is using silk-screen printing technique that tin cream used in welding is pre-
First it is arranged on the welding region of the material strip of radome, the heat-treated solidification of tin cream, re-melting tin when needs are welded
Cream, the activity of tin cream is ensure that, improves welding performance.And for material strip is compared to pcb board, it is small, first in the absence of brush tin scope
Device stops the problem of brush tin that brush tin is convenient, can brush tin scope it is also bigger so that the installation of radome is more convenient.
Further, the temperature of the heating is 220~260 DEG C, and the time is 2~5min.
Seen from the above description, the complete solidification and crystallization of tin cream after heating, remains the activity of tin cream, also keeps away
Exempt from material to be destroyed in winding packaging and transport.
Further, after the material strip stamping process, the radome is packed using pallet or carrier band.
Seen from the above description, with pallet packing or carrier band pack can be good guard shield cover, and transport it is more square
Just.
Further, radome and pcb board are positioned in reflow soldering in the lump after radome is positioned on pcb board,
To melt the tin cream.
Seen from the above description, fusing tin cream and weld job can be continuously finished in reflow soldering, save equipment and process.
Embodiments of the invention one are：
A kind of shaping of radome and installation method；
The material strip of radome is provided；
Using silk-screen printing technique by tin cream brush in the default welding region of material strip；
Obtained material strip is heated, the temperature of the heating is 220~260 DEG C, and the time is 2~5min, is made
Tin cream solidifies；
Stamping process is carried out to the material strip, is molded radome, the radome is packed using pallet or carrier band；
The radome is positioned on pcb board, the weld for making the tin cream on radome be placed on pcb board；
Radome and pcb board are positioned in reflow soldering by radome in the lump after being positioned on pcb board, with described in fusing
Tin cream；
Radome is welded on pcb board.
In summary, the invention provides a kind of shaping for welding the radome that yield is high, brush tin is convenient and cost is low and
Installation method.Under prior art it is general all with steel mesh printing or silk-screen printing by tin cream brush on the pad of pcb board, its brush tin
It is difficult, can not place the shortcomings that tin cream for a long time and can not solve always.The thinking solved the problems, such as, also all the time around how by tin
Cream is preferably brushed on pcb board.
And shaping and the installation method of the radome of the present invention, creatively will tin used in welding using silk-screen printing technique
Cream is pre-set on the welding region of the material strip of radome, generates unexpected technique effect.Tin cream is heat-treated
Solidification, re-melting tin cream when needs are welded, ensure that the activity of tin cream, improves welding performance.And material strip compared to
For pcb board, in the absence of the problem of brush tin scope is small, component stops brush tin, brush tin is convenient, can brush tin scope it is also bigger,
So that the installation of radome is more convenient.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalents that bright description is made, or the technical field of correlation is directly or indirectly used in, similarly it is included in this hair
