The bare pcb has lead HASL finish. Components are lead-free and lead-free solder was used to solder the plate-through components. Is this acceptable or will there be reliability issues?

If you use the calibration plate and stencil, that should fix the problem. I think that you are not saving the result from the calibration test. Double check manuals and probably with DEK technician, but it sounds like you are missing a step.

check if the top plate which is used for tray change is on it's place, also in manual mode you can see on Sig.IO page all sensors status and you can figure out which sensor is activated

I agree. Just thinking.. could it be copper plating issue as well? anyway, would be interesting to see some photos. Sounds like solder (from HASL process, wave or even poorly washed SMT solder paste) to me.

Here are some of the issues im having. 1. is the Dark Vias 2. The Excess Plating i have been talking about All input is appreciated

Recommended land and solder pattern says: VIA wall plating, via holes should be tented with solder mask on the backside and filled with solder. Solutions at this moment ? Thanks for all :)

We all agree that you have a PCB issue. It would be for the best if you use a lab to investigate a few of these PCBs. It would be interesting to investigate the plating specs and contamination levels. For a start you should insist on proper packaging

M_, the parts may be similar but the boards look to be different. Is the thermal relief for each lead on each board the same? what is the board finish, HASL, Enig, OSP or other? The part itself may not be your problem but the part that is partial pla

hello, Does anyone know about the value of components ˇDIODE AND REZISTORˇ near MOSFET transistor Q13 IRF840 on the board Mydata Plate K-029-0016 Elmo Power. Thanks
