During reflow soldering, sometimes via fill with solder leaving the solder connection starved. Questions are: * Specifically, what is the problem you see? * Do the defective pads show that solder has melted in a uniform fashion? * How do the tempera

The problem that I see is the pads not soldered and I can see on the X-Ray the solder on the pad after reflow, and yes the solder has melted in a uniform fashion, I have not measured the diference of temperatures in each pad of the PCB, the size is a

. If the temperature is too low, the solder will not melt after reflow soldering. Reflow soldering zone temperature setting: The temperature of the reflow soldering zone is the peak temperature of the reflow soldering
