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.

I have three through-hole PCBs that are missing front and back solder mask openings for two of the components. The solder mask (usually green) is covering the front and back solder pads. All other pads for all other parts are exposed. Is there a good way to remove the solder mask so that I can solder the components to the board?
Our brand was focused on common electronic product with single PCB. And this year, we plan to develop a smart range which may require multiple layer PCB. Want to know more about 2 laag PCB of 4 laag PCB.
We are a trading company with a heath care brands. We just hesitate about whether design the medical device PCB by ourselves or outsource the design.
