It is often important.
Printed steel mesh is the mould for print solder paste, is taped against by steel mesh opening leakage on pcb board pad during print solder paste,
Printed to by steel mesh opening size on pcb board pad, then cross stove.SMT prints tin two-sided processing procedure generally by the way of at present
It is first printing, paster, backflow production wherein one side, then after reprint, by printing again, flow back production another side again.Twice
Reflux course just needs one backflow furnace apparatus of increase, so as to add the energy consumption of unit output value；Meanwhile in printed on both sides,
When being printed after reprint, the tin cream on its another side is more easily damaged.
Therefore, how to solve the above problems, be the content to be studied of those skilled in the art.
The content of the invention
To overcome above-mentioned deficiency of the prior art, the utility model purpose be to provide it is a kind of it is simple in construction, be produced into
This low SMT printing tool.

And bottom plate；The printing screen includes silk screen body, and the print matched with the printed circuit board is offered on the silk screen body
Brush hole；Four corners of the silk screen body are provided with positioning hole；Also offer on the bottom plate and matched with the printed circuit board
Printing hole；The positioning hole corresponded on the bottom plate on the silk screen body is provided with matched fixing hole；The printing silk
The accommodating chamber for housing the printed circuit board is formed between net and the bottom plate.
In above-mentioned technical proposal, related content is explained as follows：
1st, in such scheme, the printing screen is the magnetic steel disc that thickness is 0.2mm.
2nd, in such scheme, the circumference of the bottom plate is provided with arc concave edge.
3rd, in such scheme, four angles of the bottom plate are provided with the triangle inserted for the corner of the printed circuit board
Fixing groove；The fixing hole is also provided on the cell wall in the triangle fixing groove.
Because above-mentioned technical proposal is used, the utility model this have the advantage that compared with prior art：
The utility model fixes printed circuit board using printing apparatus, using printing-turnover panel-printing-paster-backflow again
The typography of welding-cleaning printed circuit board, a solder reflow step is eliminated compared with traditional handicraft, while save one
Flow back furnace apparatus, reduces the energy consumption of unit output value, has saved cost, simplify typography, improves printing efficiency and print
Brush quality, and tin cream destroyed risk when avoiding production.
