I've been working on my first multi-layer PCB design, and have been placing a variety of components on the secondary side of the board (mostly decoupling capacitors and QFN ICs). However, some of these components are fairly large, and I am beginning to wonder whether they would fall off the board during reflow.
- Is there a general guideline dictating the maximum size of passive components allowed on the secondary side of the board? Is 0805 too big?
- At what point does a component become too heavy for the secondary side? Would a ~14mg (0805) inductor be likely to fall off?
