I think Steve is on to it. The wire is not getting hot enough to wet. Either the solderer is attempting to solder too quickly, or the PTH is connected to a ground plane. The solder sticking up through the hole leads me to think it's connected to a

Hi, We have been manufacturing a PCB, however it's been quite tricky to profile, as the edges of the PCB are reflowing before the center of the PCB. I have looked at the design, and there is a small power plane for 2.5 Volt in the center of the PCB
