I have dealt with Whiskers before but this is a new one on me.
Has anyone here dealt with something like this and know what the possible causes are?
It is a crystal type substance.
The PCB has been assembled for only a month so this is rapid growth.
There is also a blue, mold type substance, growing on the PCB beneath the affected components.
The components (4 total) are BTS621L1 Two Channel High-Side Power Switch
The cut pin at the center is the Vbb Power Supply In. It is shorted to the tab, that is why it has been removed. +13 volts.
The post to the left is the Diagnostic Feedback. The pin on the right is Input to Channel 1.
The stuff is causing faults in the system from the feedback circuit which in turn is responsible for system shutdown.
It is not in a caustic environment.
