Hello Prahlad,

The approach of measuring compnents to sort out components is tedious but doable. This is because any well centred mass production technique would produce components whose values are scattered in a value around the nominal / target value in a bell curve. So if you cull components from a 1% batch you would get a better yield than if you use a 5% tolerance batch.

As Steve mentioned it depends on the accuracy of the measuring apparatus and the environment of measuring(temperature).

This method is used in a process called selective assembly in mechanical engineering parlance.

Maybe it can be mapped to the electronic sphere too.


Kind regards
