Title:
POWER MODULE AND METHOD FOR MAKING SAME, AND POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/004153
Kind Code:
A1
Abstract:
The power module (1) is provided with a plurality of conductive wire groups (30, 30, 35) and a sealing member (60). The plurality of conductive wire groups respectively include first bonding parts (30m, 30m, 35m) and second bonding parts (30n, 30p, 35n). The maximum interval between intermediate sections of a pair of conductive wire groups adjacent to each other is larger than a first interval between the first bonding parts of the pair of conductive wire groups adjacent to each other. The maximum interval between intermediate sections of a pair of conductive wire groups adjacent to each other is larger than a second interval between the second bonding parts of the pair of conductive wire groups adjacent to each other. Consequently, the reliability of the power module is improved.
