Mistake, and can realize that electronic component inserts or attachment, automatic tin soldering, automatic detection automatically, ensure that the quality of electronic equipment, mentions
High labor productivity reduces costs, and easy to repair.Printed board develops to two-sided, multilayer and flexibility from single layer, and still
It is old to remain respective development trend.Due to constantly developing to high-precision, high density and high reliability direction, body is constantly reduced
Product reduces cost, improves performance, so that printed board still maintains powerful life in the development engineering of future electronic equipment
Order power.Summary is substantially coincident to the discussion of the following PCB Production manufacturing technology developments both at home and abroad, i.e., to high density,
In high precision, fine pore, thin wire, thin space is highly reliable, multiple stratification, high-speed transfer, light weight, and slim direction is developed, in production
Simultaneously to productivity is improved, cost is reduced, reduces pollution, adapts to multi items, the development of small lot production mode reform.The skill of printed circuit
Art development level, generally with the line width in printed board, aperture, plate thickness/aperture ratio is representative.
However existing PCB circuit board welding with laser steel mesh in use there is some shortcomings, it is big
Most structures are simple, are single layer mesh-plate structure, offer big and small multiple scolding tin holes on it, and in actual use,
Due to the difference of PCB circuit board, it is desirable that the size and shape in scolding tin hole can there is some difference, the weldering of existing laser steel mesh
Tin hole size is fixed, non-adjustable, so that the processing quality of scolding tin result is not high.
Utility model content
The purpose of this utility model is that: simple in order to solve existing laser steel mesh structure, the size fixation of scolding tin hole can not
It adjusts, leads to the problem that final product quality is not high after processing, a kind of PCB circuit board welding laser steel mesh is provided.
The technical solution adopted in the utility model is as follows:
A kind of PCB circuit board welding laser steel mesh, including outer layer steel mesh and internal layer steel mesh, the inside of the outer layer steel mesh
Offer hollow sandwich, the internal layer steel mesh is arranged in the inside of hollow sandwich, the two sides of the outer layer steel mesh open up it is fluted,
And guiding tooth is equidistantly evenly arranged on groove, one end of the guiding tooth is provided with vernier knob.
Wherein, scolding tin hole, and internal layer steel mesh pair are offered on the corresponding position of the outer layer steel mesh and internal layer steel mesh
Should shape size in scolding tin hole on outer layer steel mesh it is all the same.
Wherein, the scolding tin hole is provided with rectangle, ellipse and round three kinds of shapes altogether.
Wherein, the external tooth being meshed with guiding tooth is provided on the outside of the vernier knob.
Wherein, the two sides of the outer layer steel mesh are provided with guide rail.
Wherein, the internal layer steel mesh is slidably connected by the way that guide rail is opposite with outer layer steel mesh.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, in the utility model, by the way that the laser steel mesh of traditional single layer structure is re-established as multilayer architecture, i.e., one
Offered among block and be provided with one piece of internal layer steel mesh in the outer layer steel mesh of hollow sandwich, meanwhile, offered on internal layer steel mesh with
The scolding tin hole of the identical structure size of outer layer steel mesh, and position is corresponding, thus in actual use, by adjusting internal layer steel mesh
With the relative position of outer layer steel mesh, it can be realized and scolding tin hole size is controlled, meet actual operation requirements.
2, in the utility model, internal layer steel mesh is by vernier knob and the guidance of shaft, when needing to adjust welding hole
Size when, only need to turn vernier knob, can be realized vernier knob moving horizontally in guiding tooth, and then drive internal layer steel
Net along guide rail and outer layer steel mesh do it is corresponding move horizontally, it is easy to operate.
