Do electronics degrade?
Semiconductors are very sensitive to temperature changes and are therefore the main cause of degradation of active components.
temp also afect, ie piezo crystals that lose their polarization capacity at a given temperature (depends on the material, 600k for pzt nt2,3 and 6)
yes many elements do not degrade . degradation can be internal and chemical or external and physical and chemical. Here are some cases that I saw.
electrolytic capacitor frozen and ice damage the sheet structures. usually shorts, half of which will fail permanently and the other which will heal. some fail open. some explode in small pieces of foil everywhere.
loses the seal (frozen or dissolved by the solvent) and moisture escapes as long as there is not enough electrolyte and leaves.
long storage and electrolytic surfaces fade. loses notes. will regain its ranking if connected again to the polarizing power supply.
solid state – the cleanliness of the plants (before 70 years old) was not clean enough. storage failure / w duration
printed circuit boards
edge pads – silicon aerosols contaminate surfaces in the form of long-chain polymeric plastics (insulators)
metallized holes. corrosion if moisture gets in.
The heat of the resistors, the power chips, if they are sufficient to melt the solder, create a poor seal. subsequent easy failure.
Shielded tin cans for circuits – can form tin whiskers with time that bypasses.
vibration degrades everything.
resonance of heavy parts at the vibration frequency.
degrades solder connections
use causes gold to rub on flat, round pins.
if used outdoors and not airtight corrosion due to moisture present between different metals.
the vinyl wire emits chlorine. combined with local moisture, hydrochloric acid is the usual reason why metal parts lose their outer coating and cover a matt crystalline surface of corrosion. Teflon wire
– excellent properties at high temperatures but subject to creep. any constant pressure such as fasteners, clips or edges causes teflon migration until the inner copper comes in contact with other conductors.
filament lamps become weak as the lamps get older.
wear contacts, corrode, sting and are burned.
