Can the product still function after storing it for several years?

Latest Updated:04/01/2009


I have a product whose production was stopped several years ago.
It has been left at room temperature for several years.
Is there any difference between using a product immediately after production and after storing it for several years?


Power supply makes a product progresses The degradation.
If the product is a plastic package product and has never been mounted, bake it in order to dehydrate it before using it.
Also check that the leads are not rusty and check the solder wettability.
Generally, the guaranteed storage period of a product is 2 years after shipment.
