What are some of the benefits and downsides of moving from a two layer PCB with components on a single side, to a four layer PCB with components on both sides?

Two-layer is cheaper, while the four layers will cost more. Dlatego

• There are twice as many layers to etchand then laminate.
• It will take almost twice as much work, steps and materials to fabricate.
• It will also take two montaż passes for pick and place instead of one.
• Anything manually placed through hole will also take one more pass for the second size.

Only drilling and 2 silkscreen and 2 solder resist will remain the same.

Compared to four layers, double sided

• will allow a significant gain in component density.

Primary side	taller stuff, large scale ICs and connectors
Secondary side	low profile passives (rezystory chipowe & kondensatory) and perhaps low profile ICs and diodes, signal transistors

• That will allow a smaller PCA footprint, so the PCA costs are saved in enclosure and overall size. A zatem, the user-friendly weight of PCB will suit portable equipment.
