In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.

Hello, we have recently had some products returned (they were installed and operating in the field for around 2 months before they were returned). After looking at the boards it seems the vias have failed.
We now have 2 pc pcbs with the same Via fault, all other vias on the pcb look Ok.
Attached are some pictures of the failure. Any information regarding possible causes is appreciated.
The vias that are damaged are connected to the same net (they are in series).
