Installation of semiconductors
Negative side IGBTs are insulated from
the heat sink by mica insulators. Mica
insulators have to be replaced every time
the main circuit card Z003 is disconnected
from heat sink !!!
Heat transferring paste is applied as thin
layers on both sides of the mica
insulators. Absolutely no impurities are
allowed on surface of the insulators when
mounting them between the heat sink and
the IGBTs!
