| I am interested in seeing how some of you quote smt work. Currently we quote off a bom without component packages known then look in data books to find out what type of component they are. This job will be mine soon but i really believe there is a

Thanks a lot,, so assuming we are using standard parts, with nothing out of the ordinary we could safely assume that a machine capable of 20 mil would be more than able to meet our needs down the road. | We are changing from through-hole to SMT, won
