¿Cuáles son algunas de las ventajas y desventajas de pasar de una PCB de dos capas con componentes en un solo lado?, a una PCB de cuatro capas con componentes en ambos lados?

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

• 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 montaje 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 (resistencias de chip & condensadores) 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. Así, the user-friendly weight of PCB will suit portable equipment.
