Improve as the one for wiring board through hole welder of the present invention, shape of through holes and the size of described mozzle and wiring board match.
Improve as the one for wiring board through hole welder of the present invention, described mozzle is set to hollow circular configuration or hollow ellipse structure.
Improve as the one for wiring board through hole welder of the present invention, the thickness of described template is 1 ~ 4mm.
Improve as the one for wiring board through hole welder of the present invention, the thickness of described template is 3mm.
Improve as the one for wiring board through hole welder of the present invention, described positioning framework is provided with the detent for placing wiring board.
Improve as the one for wiring board through hole welder of the present invention, one end of described mozzle and the top of described template maintain an equal level, and the other end of described mozzle stretches out in the bottom of described template.
Another object of the present invention is to provide a kind of for wiring board through hole welding method, comprises the following steps:
A, according to wiring board make weld template accordingly, then wiring board is placed on positioning framework and positions, adjustment welding template make itself and wiring board contraposition;
B, the tin cream that matches is detected after by stencil printer note tin in welding template, then tin cream flows on the corresponding through hole of wiring board by the mozzle of welding template again;
C, solder is released in corresponding through hole welding position by mozzle, then inserts components and parts at lead to the hole site;
D, finally by Reflow Soldering/infrared ray, through hole and components and parts to be welded.
Directly encourage tin cream by above-mentioned through hole welding method to be released on through hole welding position, and then welded by the hot blast noncontact of Reflow Soldering, therefore can obtain the welding quality of SMD welding procedure, significantly reduce fraction defective, improve utilization rate of equipment and installations and cost input.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description, the present invention is described in further detail, but embodiments of the invention are not limited to this.
embodiment 1
As shown in Figure 1, a kind of for wiring board through hole welder, comprise stencil printer 1, pressure roller 2, positioning framework 3 and welding template 4, pressure roller 2 and positioning framework 3 are all arranged at stencil printer 1, welding template 4 correspondence is arranged at above positioning framework 3, welding template 4 correspondence is arranged at the below of pressure roller 2, welding template 4 comprises template 41 and is embedded in the mozzle 42 of template 41, the present embodiment directly can also hollow out in template 41, replace the function of mozzle 42, can cost be saved like this.The positioning framework 3 of the supporting corresponding product size of above-mentioned welding template 4, by the pressure of pressure roller 2 by tin cream water conservancy diversion in wiring board via pad, thus realize the object of welding.
Preferably, shape of through holes and the size of mozzle 42 and wiring board match, because the through-hole structure of the wiring board of different size is different, so will meet welding procedure, the shape of through holes of mozzle 42 and wiring board and size just must be allowed to match, thus realize effective note tin and welding.Mozzle 42 is set to hollow circular configuration or hollow ellipse structure, is conducive to the mobility improving tin cream, makes tin cream can be covered with through hole fast.
Preferably, template 41 is made of copper, and the thickness of template 41 is 1 ~ 4mm, and the thickness of the template 41 of the present embodiment is 3mm, meets general welding process requirement.One end of mozzle 42 and the top of template 41 maintain an equal level, and the top making template 41 is a plane, are conducive to pressure roller 2 and carry out rolling printing; The other end of mozzle 42 stretches out in the bottom of template 41, and exceed the length of mozzle 1/42nd 2, the reason of such setting is: after carrying out paster technique, have components and parts, and mozzle 42 stretches out in the bottom of template 41, is conducive to reserving space and avoids components and parts height.
Preferably, positioning framework 3 is provided with the detent 31 for placing wiring board, can also be equiped with positioning fixture, for fixing circuit board in detent 31.
