How to prevent quality problems of standing monuments during PCB soldering?

Printed circuit board (PCB) problems can be a challenge, but not all of them lead to premature obsolescence of your PCB, such as the monolithic effect. The monolithic effect is caused by the uneven surface tension created during the melting of solder paste on opposite sides of a passive component. These unequal forces cause one end of the passive component to lift up and break contact with the circuit, creating a phenomenon very similar to that of a monument in a cemetery (see Figure 1).
