The soldering process for each side of the PCB is the same.
Meestal, the surface tension will be enough to hold a BGA in place, given the number of balls compared to the weight of the chip. If it is not the components will be glued, but it is quite rare to need to do it.
By design, one should avoid putting heavy components on each side of the board. On the bottom, there should only be small components.

We found that edge-mounting a TO-Can package to a PCB will really save a lot on manufacturing. Echter, it comes with fairly long through-hole pins that are taking up too much space to reach the pads. Any suggestion?
Het is een mooi uitziende broodplank, maar de aansluitingen zijn te los om een goede verbinding te maken met alle componenten. dus ik kon ze eigenlijk nergens voor gebruiken.
This question is about the advisability of continuing to use a USB mini-B right angle surface mount connector in my pcb designs. On occasion we see one of these connectors peel back or delaminate off the pcb. Immediately the question is asked, why didn’t you use a through hole connector?
