Typically, you PnP SMT’s and reflow them, push them down the line for through hole insertions and then through the wave. Seeing as the vias are open, it hasn’t been wave soldered. It may not require it either depending on the board. My guess is the chip resistor wouldn’t survive a wave solder machine as there’s usually a blower on the exit from the wave to start cooling the boards.
Edit: As an aside, you need to turn up the heat or reduce the travel rate based on those reflow joints. Your paste isn’t getting hot enough to reflow properly.
Big boy, double decker…
The classic double r36
“speced it 2x too big, can the machine cope?”
“no problem boss”
We call that “bonus resistor” its a feature
Is it electrically connected on both sides?
I’m a production engineer in a PCBA fab. I feel this in my soul.
How would that survive a wave?
That the T for “You’re fuckT”
That wasn’t deliberate, was it? You can legitimately stack resistors to parallel them, but the bottom one can’t be on edge like that.
Is this a duplicate (additional) line in your PnP process or did machine think first part was dropped?
Odd coincidence that [54C] is close to 36kΩ and it’s at R36 refdes.
Also you solder looks a little ‘lumpy’ particularly on RHS in this image, perhap reflow profile or a paste issue.

Did this pass AOI? I could almost see that as a pass if it was just inspecting top down and the value was numerically correct.
