Just would like to inquire about contract manufacturing costing:
a) if I send my bds. to a CM with a line of 2 chipshooter and 1 IC mounter and will use only 1 chipshooter and the ic placer for my product, do they need to charge me with the utilisation of 1 of the chipshooter when they r using it for theit product? Does the cost of placement need only to be calculated for the 2 machines they are using?
b) Id like to get Ideas on how a CM charge per component placement or per PCB and the average rate available in the market mainly in US.
c) Also when they say their line is capable of placing 55,000 CPH, how did they come to this and how do they come up to that if they have 3 machines per line.
Thanks and regards
