Placement Cost per component categories

Electronics Forum | Thu Aug 01 07:52:37 EDT 2002 | GregH

Are all components calculated at the same cost when calculating cost per placement? Are they categorised according to their sizes / dimensions as per machine placement speed or are they also categorised as per component technology? Can anyone give me

Machine utilisation
