Do you happen to know if tin whiskers have anything to do with passing current? (in other words, will a device that's in constant use develop them faster than a physically identical device that's switched off and in storage)
- londons_explore 5y agoPassing current means thermal cycling... And thermal cycling definitely accelerates whisker formation.
- hulitu 5y agoYes. Voltage has a big effect on whiskers.
