| Popis: | We developed a screening equipment for ceramic substrate level power module of IGBT. The equipment realizes a new screening test with current distribution. The equipment acquires magnetic field signals over bonding wires and finally classifies to normal/abnormal module automatically. We established statistics based normal/abnormal classification with image processing. It is expected to be applied for screening in a production line and analysis to prevent the failure of power modules. 2017 29th International Symposium on Power Semiconductor Devices and IC's (ISPSD), May 28 2017-June 1 2017, Sapporo, Japan |
