Technical field
The present invention is mainly concerned with IGBT modular design field, refers in particular to a kind of high-power IGBT module of integrated gate electrode resistance distribution.
Background technology
Current, mainly comprise liner plate, igbt chip, gate electrode resistance, power terminal etc. in the IGBT module.As shown in Figure 1, for having the liner plate 5 of typical IGBT now.In IGBT module package process, in order to control the switching speed of igbt chip, usually need to be at each igbt chip gate pole gate electrode resistance 2 in parallel.Existing methodical step is: at first, according to the circuitous pattern on the liner plate 5, with silk-screen printing technique with the corresponding region of Solder-Paste Printing at liner plate 5.Secondly, utilize the adhesiveness of soldering paste, gate electrode resistance 2 is attached to the corresponding zone that is printed with soldering paste.At last, utilize welding procedure that gate electrode resistance 2 is welded in the corresponding liner plate circuit.
But, current with gate electrode resistance 2 design on IGBT liner plate 5, mainly contain following some problem: 1, packaging technology efficient is low: because gate electrode resistance 2 is very little, be attached to by artificial means on the IGBT liner plate 5 inefficiency.2, affect processing compatibility: must use the soldering paste welding procedure at liner plate 5 welding gate electrode resistances 2, can't use the weld tabs welding procedure, affect the compatibility of packaging technology.3, limited the layout designs of IGBT liner plate 5: gate electrode resistance 2 is welded on the liner plate 5, has increased the complexity of liner plate 5 layouts.Because standard liner plate 5 sizes are fixed, gate electrode resistance 2 can take liner plate 5 circuit, affects the diversity of liner plate 5 layouts simultaneously.
Summary of the invention
The technical problem to be solved in the present invention just is: for the technical problem that prior art exists, the invention provides a kind of simple and compact for structure, with low cost, can improve gate electrode resistance welding procedure efficient, simplify the high-power IGBT module of the integrated gate electrode resistance distribution of liner plate circuit design.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of high-power IGBT module of integrated gate electrode resistance distribution comprises pcb board, busbar and liner plate, and described liner plate links to each other by the gate pole spring wire with pcb board, directly is welded with gate electrode resistance on the described pcb board.
As a further improvement on the present invention:
Described gate electrode resistance adopts pinned resistance.
Compared with prior art, the invention has the advantages that:
1, the present invention utilizes existing pcb board in the IGBT module, integral gate resistance.Utilize ripe PCB technique welding gate electrode resistance, then utilize spring lead-in wire connection PCB circuit and liner plate circuit, realize that gate pole is interconnected, can improve the process efficiency of gate electrode resistance welding.
2, the present invention peels off gate electrode resistance from liner plate, need not to weld gate electrode resistance on the liner plate, can increase the compatibility of liner plate welding butt welding blade technolgy.
3, the present invention need not to weld gate electrode resistance at liner plate, can simplify the liner plate circuit design, and the space of more liner plate layout designs is arranged.
