Abstract
The invention provides a high-power IGBT module soldering device. The soldering device comprises a soldering lug fixing tool, a liner plate fixing tool and a positioning pin, wherein the soldering lug is consistent with a soldering lug in thickness and provided with a through groove for fixing the soldering lug; a through groove for fixing the liner plate to be welded is formed in the liner plate fixing tool; a through groove used for fixing a liner plate to be welded is formed in the liner plate fixing tool; the soldering lug fixing tool and the liner plate fixing tool are respectively provided with a positioning hole corresponding to the positioning pin. Formed sheet soldering flux (soldering lug) without scaling powder is adopted and put in the specific tool, so that positions of an area to be soldered, the sheet material and a liner plate element to be soldered are fixed to solder an IGBT module through the soldering lug; after soldering, it is unnecessary to clean a soldered product because no scaling powder exists, and therefore not only can module assembly efficiency be improved, but also product reliability can be improved.
Description
Technical field
The present invention relates to electronic devices and components field, particularly a kind of high-power IGBT module welder.
Background technology
Power model is in the time of encapsulation at present, conventionally adopt soldering paste to weld substrate, first paste solder coating to soldered pedestal, again the components and parts that will weld (band liner plate) are placed on paste scolder, finally the pedestal assembling and liner plate are put into soldering furnace, carry out the welding of product, but in soldering paste, contain a large amount of scaling powders, after welding cleaning, residual scaling powder can make the reliability decrease of module, for the high-power IGBT (Insulated Gate Bipolar Transistor insulated gate bipolar transistor) of high reliability, because bonding area is large, need the solder paste amounts of use many, can can residual a large amount of scaling powders at element surface and welding equipment inwall after having welded, make water cleaning equipment be difficult to scaling powder on element to clean up completely, residual scaling powder will directly have influence on product long-term reliability.Because sheet moulding scolder (weld tabs) does not exist scaling powder, after having welded, do not need to clean, can reduce matting on the one hand, on the other hand, after welding, can welding cavity not produced and be polluted, there is not welding assisted agent residuals in the product of welding, can not affect the reliability of product yet.Thereby, for high reliability module, as high-power IGBT module, adopt weld tabs welding more guaranteed to product quality.But in the time that weld tabs welds, there is no adhesiveness between element, weld tabs material and substrate, in assembling and welding process, relative position easily changes, cause welding failure or welding quality to guarantee.
Summary of the invention
Based on the deficiencies in the prior art, the problem to be solved in the present invention is to provide a kind of high-power IGBT module welder.
For solving the problems of the technologies described above, the invention provides a kind of high-power IGBT module welder, comprise substrate, it also comprises weld tabs fixing tool, liner plate fixing tool and alignment pin; Described weld tabs fixing tool is provided with the run-though space one of fixing weld tabs; Described liner plate fixing tool is provided with the run-though space two of fixing liner plate to be welded; When use, weld tabs fixing tool overlays on substrate, and liner plate fixing tool overlays on weld tabs fixing tool; The alignment pin on substrate is fixed in one end, through default locating hole on weld tabs fixing tool and liner plate fixing tool.
As a kind of high-power IGBT module of the present invention welder preferred version on the one hand: described weld tabs fixing tool and described weld tabs consistency of thickness; Described liner plate fixing tool and described liner plate consistency of thickness to be welded, to reach better fixed effect.
The present invention can be fixed on the region that substrate welds weld tabs and with the liner plate of soldered element.Can, according to the substrate of different size and liner plate element, adopt the moulding flaky material of different size and thickness, and the welding tooling of the different sizes of design, realize the welding of different size product.
Tool of the present invention has the following advantages:
1. the product surface obtaining does not have the residues such as scaling powder, and product reliability is high
2. the product that welding obtains, does not need to clean, and can raise the efficiency, cost-saving
3. the product layer uniformity obtaining is relatively good, can improve the reliability of product
4. the pollution of scaling powder to equipment be can reduce, the life-span of welding equipment and the stability of Product jointing improved
Describe the present invention in detail below in conjunction with accompanying drawing, it illustrates principle of the present invention as the part of this description by embodiment, and other aspects of the present invention, feature and advantage thereof will become very clear by this detailed description.
