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

Look to IPC-2221, 9.1.3 Thermal Relief In Conductor Planes

tjc, Is this pin connected to a heavy conductor or ground plane? Chris

Most likely ground plane stealing your heat. Increase dwell slightly if you can.

When you sat design problem, is it a because there is a ground plane causing a thermal problem?

Windowpane your ground planes, this will prevent a lot of voiding.

Do you have pictures? it may caused by the unproper temperature or pads or the adjacent copper plane or other reasons.

Looking for advice/products on ways to get heat out of a package and into an internal thermal plane. Will have electrically isolated thermal pads (going to an internal thermal plane) under the part. Need a way to get good thermal contact between par
