Hello

I am curious about an anomaly we are seeing in the new profile for one of our products, we run it in a wave solder and after it gets solder we see that the fillets are not even, we have took x-rays of the terminal but we see 100% barrel fill, can this be a defect?

If not definitely! If so you have a little excess wicking which could be fixed on the next board run by separating them a little!

Hello thanks for the quick response actually both terminals are for a receptacle, both terminals has to have that solder bridge.

Looks possibly like the ground is sucking the heat away. look at your preheat? is it getting to 120c before wave?

What part do you think is a defect? You can see by the board that the two leads are electrically connected anyway. If you mean that the outside fillet on the right is shorter, just look at the board. It looks like you have solder mask encroaching on the pad, so the ring is partially masked over. That's why the fillet is short on that side.

Or perhaps I am not seeing what you are referencing?

If your goal is for the solder bridge to be there, then I do not see any defect. Looks like the pins and pad are wetted properly.
