I have been asked by an engineer that I am working with to restrict the top side/bottom side placement of parts according to part values (all parts are 0805's). For example if I place a 10K resistor on the bottom side, all 10K's should also go to the bottom side. He does not want me to mix parts of the same value between two sides. He tells me this will significantly reduce assembly costs. I have = never heard of such a thing. Is he correct? I believe the extra layout time will negate any potential savings in assembly setup. Any comments?
