Failures on underside layers of a chip in IGBT power modules
Does somebody know how I can detect a layer of IGBT modules in which a thermal failure, e.g., voids, cracks, delaminations of solder joints, has taken place?
We know there is fatigue in both solder ...

Electrical Conductivity of SAC solder
Can anybody help me find the electrical conductivity of SAC 305 (96.5Sn3Ag0.5Cu) solder? It is the most common solder in semiconductor IGBT/MOSFET power switches.
Many thanks and best regards,

Temperature dependance of IGBT max collector current
I have an IGBT (datasheet), that I am using as a switch for a coilgun. How would I calculate the maximum pulse collector current in function of the ambiant temperature and time?
Also, if we're ...
