Actually, it applies to conditions from cold to hot AND hot to cold. The measure of T is graphed against time. Time is what you measure the difference of temperature against. I was hoping to influence this engineer to find this out on his own, but

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

Has anyone had any experience using REM Oil for their feeders or other SMT Applications? I have talked to a few techs around the states and they said it is some of the best lube for feeders. Just looking for some feedback, Thanks.

Hi all, Has anyone ever worked on one of these machines before. I'm looking to hear other peoples opinions/experiences on the machine. Any problems with software hangups, 2d teaching or anything else? Looking forward to your replies
