Abstract

The utility model relates to a trepanning structure used for a printed circuit board printing processing step steel board. The trepanning structure includes a steel board frame; a wire screen is arranged on the steel board frame; a steel sheet is placed on the wire screen; and an etch-hole is trepanned on the steel sheet. According to partial specific assemblies, such as an inductor or an LED, the steel sheet is locally thickened or thinned through a semi-etching way, as a result, two or more than two kinds of thicknesses can be formed on the same steel sheet; and therefore, the trepanning structure can be used for solving the technical problem that solder pastes with different heights are required to be printed on the same PCB. According to the trepanning structure of the utility model, the step steel board is selected to be trepanned according to the specific assemblies; the problem of poor welding such as missed welding and insufficient welding produced in the processing of high-end products can be solved; maintenance cost can be reduced; yield and the production efficiency of enterprises can be increased; and the stability in welding can be improved.

Description

A kind of open-celled structure for printed circuit board (PCB) printing process ladder steel plate
Technical field
The utility model relates to part field, and what be specifically related to is a kind of open-celled structure of printed circuit board (PCB) printing process ladder steel plate.
Background technology
At present, along with the high-tech develop rapidly in the world, electronic product is to miniaturization and multifunction development, short and small frivolous be global main flow trend, so also high precision int more and more of printed circuit board (PCB).The SMT technology has become main flow, and Paste Solder Printing Process is proposed strong challenge.Also more and more higher to the steel plate designing requirement simultaneously.Good perforate design can promote typography backflow ability and quality, and partly particular components has very high welding requirements.
The utility model content
At the deficiency that exists on the prior art, it is when print product is provided to provide in a kind of printing process that the utility model provides purpose, the open-celled structure of thickening or attenuate printing stencil.
To achieve these goals, the utility model is to realize by the following technical solutions:
A kind of open-celled structure for printed circuit board (PCB) printing process ladder steel plate of the present utility model comprises the steel plate frame, on the steel plate frame silk screen is set, and steel disc is placed on the silk screen, offers etch-hole on the described steel disc.
Preferably, a side of described steel disc is offered etch-hole or etch-hole is offered in both sides.
Preferably, bonding by glue between described steel disc and the silk screen.
Preferably, described silk screen is 100 order steel wires, and the steel plate frame is steel plate aluminium frame.
The beneficial effects of the utility model are: the open-celled structure for printed circuit board (PCB) printing process ladder steel plate of the present utility model, a kind of form technology that produces for same PCB of solution goes up the difference of tin cream demand thickness, be attenuate or the thickening of template part with the difference of common templates, simultaneously, be used for the article that when printing, need avoid having carried on the PCB and " hollowing out " in template and PCB contact-making surface.
Description of drawings
Fig. 1 is the cutaway view of the open-celled structure for printed circuit board (PCB) printing process ladder steel plate of the present utility model.
Among the figure: 1, steel disc, 2, etch-hole.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
In conjunction with shown in Figure 1, the open-celled structure for printed circuit board (PCB) printing process ladder steel plate of the present utility model comprises the steel plate frame, on the steel plate frame silk screen is set, and steel disc 1 is placed on the silk screen, offers etch-hole 2 on the steel disc 1.
One side of described steel disc 1 offers etch-hole or etch-hole is offered in both sides.
Wherein, the quality of steel disc material and steel plate have certain degree of influence useful life, select for use to have the hardness height, and be nonmagnetic, the stainless steel substrates of corrosion resistant performance.
Silk screen namely connects the net that stretches tight of steel plate aluminium frame and steel disc, selects 100 order steel wires for use, and the big evenness of tension force is good, and thermal coefficient of expansion is complementary not yielding with stainless steel substrates.
Glue is used for stick steel plate aluminium frame and steel disc, selects the AB glue that possesses big sticking strength and shear strength for use, and anti-solvent is high temperature resistant.
The hybrid technique of chemical etching+laser cutting is taked in the making of ladder template.
The concrete operations explanation:
1, adds etching solution
2, development pad pasting
3, exposure printing ink
4, UP and DOWN time are controlled.
The part of the utility model steel plate or ad-hoc location are thickeied steel disc technology, have increased the print thickness of this ad-hoc location, and the empty weldering of improvement and few tin are bad, are applied to PTH through hole assembly especially, SMT CONN assembly etc.
The part of the utility model steel plate or ad-hoc location attenuate steel disc technology are used for the 0.4pitch assembly, promote stripping result, satisfy flakiness ratio>1.5 of steel plate opening design, and the SPEC of area ratio>0.66 has improved printing Lian Xiyu and drawn point bad.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
