Let me add to the Mydata thing.. TP9-2U=..... TP9UFP=Good MY9=Best TP9 UFPs will place 0402's fine as long as you have black tools and run them across the camera. This method is slow but it works.

I agree with Steve Thomas, The Quad IVC is a good machine for what you have described, it is small, chugs right along and is dependable. 1 head makes for some boredome watching it but is well over the 500 component mark. Good Luck with your purchase.

Actually I didn't see anything saying this person was an engineer, but I digress.... In this case this person may very well be referring to the delta t across space rather than over time, as in different locations on a pcb that's being profiled.

Ah, see Steve, I was right. It depends Marcin. If you use the same temps in each zone for all your product, vary you converyor speed. This will negate any waiting time between profiles. Slowing the speed will decrease your Delta-T to an acceptabl
