you will have to look at the legs of the transistor. If it's a three
legged transistor, you will probably shadowing by the component body.
Solder doesn't usually make 90 degree turns....it flows. For the
capacitors, you probably need more control of the process. Try speeding up
the conveyor a bit to decrease the dwell time. Just a thought.

Subject: [TN] solderability problem
Hi
Is there anyone who can give me an advise regarding the no solder
problem I encountered on my board. It always occur at transistor,
sometimes it does not have any solder after passing the solder wave.
I already conducted different loading orientation just to know what
is the rootcause of the said problem, but still no solder.
Other problem, the chip capacitor crack after wave soldering .
Kindly give me advise on how to prevent this problem.
