Why do people use multiple layers PCB? What are they required for?

We seldom use multiple layers in our product ranges, which cover all types of smoke alarm. What are they required for? Any advantages?

Simplify PCB Traces

Multiple layers make it easy for the PCB traces to route by jumping over from one layer to another to complete the path. Hence many complex circuits can be routed easily.

Compact

Also the demand for compact electronic devices boosts the need for multiple layers PCB.

Isolate Supply and Ground

In PCBs with 4 of meer lagen, supply and ground is separated. This offers isolation between supply and ground pins and hence avoids short circuit.

On which layers of four should the trace antenna be (433mhz)

Our team plan to launch a GPS device for food safety tracking, with a four layers PCB inside. Where should we locate the antenna?

How can I handle missing solder mask opening on PCB footprint?

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?

How can I determine BGA land pad diameter for given ball diameter?

I’m working on a project which requires the use of a CSP package. The product’s datasheet provides ball pitch and ball diameter but nothing about the preferred land pad diameter.
How can the pad diameter be worked out from these figures assuming an NSMD land?
