    "If all the IGBTs are good, then all the SMD resistors, capacitors and zeners on the legs of the IGBTs are good"

    Is there such a thing as "If all the IGBTs are good, then all the SMD resistors, capacitors and zeners on the legs of the IGBTs are good" in the inverter welding machines? That is, as long as at least one of the IGBTs does not explode, will the SMD elements underneath remain intact?
