[0049] Following with reference to the present invention will be further described.
[0050] like figure 1 with 2 , According to a first aspect of the present invention, the present invention provides a dynamic test fixture IGBT device, comprising a first jig 100, supporting frame 300 and second clamp 200. Wherein the first clamp 100 for clamping the first IGBT device 120, the second clamp 200 for clamping the second IGBT device 220, the support frame 300 disposed between the first IGBT and the second IGBT device 120 device 220, a first a clamp 100 and second clamp 200 are located on both sides of the support frame 300, and the symmetry axis is substantially symmetrically disposed in the support frame 300.
[0051] like image 3 Shown, a first and a second IGBT device 120 to the IGBT device 220 crimp-type IGBT device will be described as an example. Both belong to a flat type power device, using the pie-shaped package. Both substantially the same internal structure, mainly composed...
