When troubleshooting intermittent components or failures by using freezing sprays or heating them up how do you know which component is bad when you freeze or heat up the Transistors or FET one by one but each one with drift in voltage up or down when its cold or hot , that doesn't mean its BAD
When I freeze or heat up a transistor , the voltage of the transistor or output of that stage will drift up or down , so how do I know if its bad or good?
When a transistor is an amplifier it will drift the voltage up or down when you freeze or heat it up, does this mean its bad or good?
When a transistor is a switch , it will drift the voltage up or down when you freeze or heat it up , does this mean its bad or good?
When resistors are temp failure, the resistance changes up or down depending on the freezing or heating it up
At work i had to do freezing spray and heating up these OP AMPS that were in the shape of a metal can transistor looking types like a IC chip package type, I had to freeze spray and heat them up ONE by ONE
But I can't tell if the transistor or these Op amps are good because the voltage will go up or down
