Did you noticed that when holding a LED with bare fingers and connect it to a soldering iron(ac type) it gets a little bright.
I did it for other components to reduce their heat during the soldering. I need to know is it ok to hold IC (ex 74hc595, mcu's, ...) Pins with fingers or metal tools when their other pins are in touch with iron tip?
Is there any reverse current ? May it damage the chip ?
