I see, maybe changing my peak temp in reflow will help. I'll try do eval again... Actually, once I did have evaluated a longer pre-heat but on my previous eval, I didn't change the peak temp. Maybe reflow can help compensate to my problem in the part

I've been running an eval on it for a little while now. Most impressive thing I've seen so far: Dispensed 100 grams on stencil, printed two solder paste eval PCBs and reflowed, put paste onto sheet of FR4 and let it sit out in the shop next to the
