Delta T usually refers to the Temperature Difference between adjoining zones in your Reflow Oven. The recommended Delta-T between heating zones is http://www.ipcoutlook.org/pdf/best_practices_reflow_profiling.pdf

How many of you run a different oven recipe for the secondary side of a double sided reflow assembly. In other words, would you use the same recipe for both sides ?

We would usually have the bottom zones at the reflow with 10 degrees less than the top ones for the secondary side. This we proved helps to keep the parts of the primary side on the board.

What does the technical data sheet for the component recommend for reflow profile ? Can you post a photo of the component ?

Reflow profiling/soldering is a process in which a solder paste (a sticky mixture of powdered solder and flux) is used to temporarily attach one or several electrical components to their contact pads, after which the entire assembly is subjected to c

I have personally never seen a reflow profile change reduce voids. We have invited "experts" in to demonstrate this claim. They were unable to.

Dear Sr.Tech, We tried to adjust the soak time and TAL time of reflow profile, but it doesn’t seem to help much.

Dear Steve, We already to do some DOE of reflow profile, but the optimized parameters are not help for the reduction of voids.

Dear CW, Yes, we also tested many different brands and models of solder paste, under the same stencil design and reflow profile the condition of the voids will have great difference.

Show us your reflow profile. Most probably that will help us to troubleshoot better.
