Guidelines to shrink the PCB size

Hello,

Are there any basic guidelines in embedded system when it comes to
shrinking the size? what are the probelms/limitations or interferences
one should consider while shrinking/sandwiching the board.

I was thinking that should be something like this:

0- Calculate the empty space in given housing. Thats the space actual
available for putting all the electronics.

1- Draft the physical dimensions of all components.

2- Now do simple PCB with few layers.
2.0- Break the PCBs in parts to fill the empty space,
connections can be done with ordinary connectors. Why not modularizing
the whole thing; LAN, Image sensor and Power circuitry etc. etc.
2.1- If the size is greater than free space then increase the
layers to adjust the components. (sure, we got to keep in mind the
heat emission and EMI if analog is involved)

3- Try to find components with different sizes with same specs.

4- And here we are in vicious cycle to fit all the thing in such a
small place , so lets start from point '2' again and keep iterating
unless we find the way-out of this puzzle.




Cheers,
ali
