Well, sample inspection should be saving some time already. What other fat are you trying to trim here? Where is your bottleneck?

Thank you dor your inputs! I was also thinking that once we verified the program to BOM and feeders, we shouldnt check to the BOM after palcement, but we should just AOI. Can you see any other weak points?

Try swapping out the motor controller boards and see if the problem moves. More than likely it is the motor, coupling or the encoder. Some of the suggestions about reducing the acceleration in the package is a good idea but this will not provide a lo

I agree with Ka. I can't think of a solder paste supplier that doesn't tell you to let your paste come to room temperature before putting the paste on the stencil.
