Bileşenlerin tek tarafta olduğu iki katmanlı bir PCB'den geçmenin bazı avantajları ve dezavantajları nelerdir?, her iki tarafında bileşenler bulunan dört katmanlı bir PCB'ye?

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

  • 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 montaj 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 (çip dirençler & kapasitörler) 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. Böylece, the user-friendly weight of PCB will suit portable equipment.
