Quais são alguns dos benefícios e desvantagens de mudar de uma PCB de duas camadas com componentes em um único lado, para um PCB de quatro camadas com componentes em ambos os 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 montagem 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 (resistores de chip & capacitores) 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. portanto, the user-friendly weight of PCB will suit portable equipment.
