Steve, Take your 'head butter' (butthead?) out to the line and let him see just how fast he can do hand placing with tweezers and a vacuum pen. I had a similar instance a few years back and quickly put it to rest by this method. We used to have to do a lot of this kind of work at a shop I used to work for out in the Sillycone Valley, a certain customer thought nothing of giving us 100 piece board runs with 60-70 line items in little bags. For quoting and manpower scheduling, I have used 20 seconds for chips/SOT/MELF, 30 for SOICs and 45-60 for fine pitch based on pitch/pin count. Though this may seem a little high, better to come out over rather than short. As I used to have to remind our Plant Manager, "It's a profit thing"....
