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

Ramp rate is measured in degrees per second. Max and min temps are not required to to establish "ramp rate". The difference between parts, like I was describing is Delta T. But, ramp rate is a generation from this as well. Most component manufact

It means "difference in temperature". It's important so you know when to put your sweater on or take it off.

Is anyone out there using "single profile" on high mix production? Or would you recommand suitable reflow oven for that? Some oven manufacturers would announce for that. We have tested four different b'ds on their oven. Results(delta t) were 20 to 2

I was asking about delta t in profiling, because I have just started to learn how to do it and wanted to know about it. So how can you reduce delta t, so you dont go from cold to hot too fats. Is it enough to slow donw conveyor speed??? Thanks M

Delta-T in reflow generally means 2 things - difference in temperature on a product or difference in temperature of your oven. Delta-T on a product is what are your hottest and coolest areas on the board. Larger parts toward the middle of the boar
